Abstract
A light-weight equivalent of a Portland cement based construction product, such as a brick, kerbstone or paving slab, comprises a mixture of sulfur polymer cement and an aggregate material. The aggregate material preferably comprises a waste material. The construction product may include one or more hollowed or cored sections to further reduce its weight. In a further aspect, sulfur polymer cement is used in the encapsulation of waste.
Description
SULPHUR POLYMER CEMENT CONSTRUCTION PRODUCTS
Field of the Invention
The present invention relates to construction products with lightweight properties, and in particular construction products produced using sulphur polymer cement.
Background of the Invention
Portland cement is commonly used in the production of a wide range of construction products due to its structural properties. Examples of construction products that can be produced using Portland cement are for example, but not limited too, bricks, blocks, kerbstones, chamber rings, culvert boxes, copings, ductings, channels, beams, lintels, paving sets, flags, paving materials, roofing tiles, section panel walling, sea defence blocks.
However the structural properties of Portland cement are such that there are limitations on the types of aggregate which can be suitably used in the production of durable resilient construction products.
Another consequence of the structural properties of Portland cement occurs when the structural requirements of a construction project (e.g. compressive strength) necessitate construction products of a certain size and weight, which in turn has an impact on the construction project with regards to minimal loading bearing structures.
I
Summary of the Invention
: *" The present invention seeks to provide lightweight equivalents of the construction products that are currently produced using Portland cement. The present invention * also seeks to produce construction products with materials that would otherwise be considered waste.
S * *
I
The present invention provides a light-weight equivalent of Portland cement based construction products, such as a bricks, kerbstones or paving slabs, wherein said construction product comprising a mixture of sulphur polymer cement and an aggregate material, such aggregate material being a waste material.
The use of sulphur polymer cement instead of Portland cement removes the need for traditionally thick or solid sections within precast concrete products because of the improved mechanical properties of SPC compared to ordinary Portland cements.
The disposal and processing of waste is also a well appreciated problem. Whilst some waste materials are suitable for re-use and recycling, there are some waste materials that at present are unsuitable and thus must be disposed of at land fill sites
for example.
These waste materials, which are generally either toxic and/or hazardous in nature include but are not limited too: Low level radioactive construction demolition waste, PU foam waste, quarry fines, PF foam waste, calcined sludge, battery waste, leaded glass waste (CRT) , mixed cullet glass waste, calcium fluoride waste, brine mud waste, bed ash, ceramic wastes, shot blast waste, slag waste -from steel rolling operations, low level radioactive waste, rigid PVC waste, asbestos wastes, mixed polymer wastes derived from material recycling facilities (MRF) local collections, low calorific value wastes, castings sands, tire waste, synthetic or natural fibre material wastes, automotive shredded residual wastes, mixed demolition wastes, WEE rejection wastes, pulverised fuel ash (PFA) organic or inorganic wastes or by-products.
By resorted to specialist land fill sites for the disposal of the above mentioned waste types, any party disposing of the waste is liable to incur high disposal costs, not least * because of transportation costs and land fill charges.
* ***** * By utilising SPC to encapsulate the otherwise difficult to dispose of waste materials the present invention provides the dual benefit of constructively disposing of difficult waste whilst at the same time producing construction products with advantages over : ** the commonly used Portland cement based equivalents. *** *
S..... S *
In fact the reduced mass of the SPC based construction products over the Portland cement equivalents provides material savings, which in turn drive the commerciality of such products.
Detailed Description of the Invention
The use of sulphur polymer cement (SPC) as a binder in civil engineering structures, materials and construction products has been known since at least the early 1970's.
The properties of SPC mean that when it is used as a binder with virgin aggregates it can produce a highly chemical resistance composition with superior properties, including enhanced compression strength compared to ordinary Portland cement concrete compositions.
Sulphur polymer cements have thermoplastic characteristics enabling the binder to be heated, moulded, recycled, re-heated and moulded again and again with minimal loss of mechanical properties, further adding to its environmental benefits and carbon reduction properties.
Sulphur polymer cement is derived as a by-product of Gas and Oil production.
However to date, the markets for sulphur polymer cement (SPC) have remained limited, due to the high cost of the material as a binder compared to ordinary Portland cements.
It is well known that access to easily sourced oil and gas fields is falling. As a result oil and gas exploration companies are now seeking to exploit oil and gas fields and reserves that have historically been deemed unattractive to exploit, in particular because of their whereabouts and/or the high sulphur content within them. Over the coming decades this will result in a huge increase of sulphur becoming available for : conversion into sulphur polymer cements (SPC) and for additional uses within : downstream applications.
The present invention sets out the properties of sulphur polymer cement within the encapsulation of waste/s and by-products that are usually destined for specialist landfill facilities. The use of SPC in waste encapsulation will reduce the reliance on specialist landfill facilities and instead provide technically feasible and commercially viable civil engineering structures, construction materials and br products.
From a commercial prospective the generation of gate fees from the diversion from landfill sites of the waste(s), by-products and residues will further assist with the end products commercial feasibility. Furthermore, it will also assist with international government aims of recycling and reuse and ally itself to the carbon reduction targets set out within documents such as PAS 2050 and the Kyoto Carbon reduction policy.
The present invention set outs the steps necessary to encapsulate waste and by-products material into compositions, blends and recipes that can produce technically feasible and commercially viable civil engineering structures, construction products and/or construction materials with the ability to utilise toxic and/or hazardous waste, by-products or residues, such as, but not limited too; Low level radioactive construction demolition waste, PU foam waste, Quarry fines, PF foam waste, calcined sludge, battery waste, leaded glass waste (CRT) , mixed cullet glass waste, calcium fluoride waste, brine mud waste, bed ash, ceramic wastes, shot blast waste, slag waste -from steel rolling operations, low level radioactive waste, rigid PVC waste, asbestos wastes, mixed Polymer wastes derived from material recycling facilities (MRF) local collections, low calorific value wastes, castings sands, tire waste, synthetic or natural fibre material wastes, automotive shredded residual wastes, mixed demolition wastes, WEE rejection wastes, pulverised fuel ash (PFA) organic or inorganic wastes or by-products.
Certain aggregates are deemed unsuitable for use within ordinary Portland cement compositions. In fact certain aggregates would give a definite acidic reading but there are some granite and other aggregates that are classed as reactive. Here reactions such as alkali silica reaction (ASR) apply. Blast furnace slag can be acidic and some may react with Portland cements to give alkali silica reaction (ASR) type reactions.
: *.* The use of PSC rather than Portland cement allows for the use of finer sized *S..
particulate material which in turn increases the waste material types that can be : used in the production of construction products.
When powdered some of these reactive materials become pozzolans and their * incorporation offers protection from alkali silica reaction (ASR) type attack. Typical examples of these materials include meta-kaolin and ground granulated blast furnace slag. In normal Portland cement concretes additional sulphate should not be added as this can cause various sulphate attack problems. Whilst the formation of ettringite is probably the best known form of sulphur attack problem, Thaumasite formation can also be a problem in some areas.
However, Portland cement is often used in formulated systems with other cements such as Calcium Aluminate cements and in these mixes additional sulphate is actually added to give shrinkage compensation. Some of these mixes can contain quite significant amounts of sulphate but since they are in formulas (like self levelling mixes) the effects are known and carefully monitored by the blender.
The main restrictions to the types of aggregates used relate to need for high aggregate crushing values and lowered risks of ASR and Thaumasite Ca3Si(C03)(S04)(OH)61 2(H20) formation.
These restrictions are defined by amongst others EN standards. Generally silica based aggregates; limestone aggregates; and most crushed igneous rock are suitable. What this means -in effect -is that there are some aggregates i.e. acidic or sulphate containing-which are unsuitable for Portland cement, but could be used with SPC The majority of the wastes identified herein would be deemed as waste(s), by-products or residues and could contain elements of heavy metals, such as, cadmium, lead and mercury plus toxins and other hazardous chemicals within their make-up. Such would therefore be classified as hazardous and as a result would generate a high level gate receipt for disposal. These materials could be presented/supplied within numerous forms, including, but not limited too; blocks, :h pulverised, shredded, granulated, agglomerated, ash, granule, pellet, mulch, : composted, castings, crushed, they would then be converted into a suitable form for downstream processing with Sulphur polymer cement (SPC) into inert civil : engineering structures, materials and/or construction product.
The use of sulphur polymer cement (SPC) when bound together with these waste, by-products or residue materials can result in stabilising or preventing these materials from leaching because of sulphur polymer cements hydrophobic properties, be it, into the atmosphere, substrate or water table.
For example, use of materials such as bed ash and quarry fines within a desired construction product composition, has demonstrated greater material performances, because of their finer particulate material dispersion compared with traditional construction material. Also sulphur polymer cement will encapsulate the heavy metal content of the bed ash from leaching into the substrate/water table during its in-situ service life as a civil engineering structure or as a construction material or product.
It is also a key requirement to focus upon the use of more recycled material within these proposed construction products, while also focusing on lowering carbon emissions which, in turn, these compositions can achieve while also eliminating the need for water as a key element within the binding of ordinary Portland cements.
The below tables provide a non-exhaustive list of waste materials, together with their respective sources, that can be utilised within the sulphur polymer cement (SPC) waste material compositions.

While processing the sulphur polymer cement material blend make sure to be taking the required adequate steps to vent off any undesired gases, vapours or moisture.
After thorough mixing is complete pour the desired material blend within a mould to set. If so required, the material can also be compressed or vibrated within the mould, after setting release from the mould. Understandably, there would be variations on this process that could change but still keeping within the original scope of the : present invention.

A principal feature of the use of sulphur polymer cements within material composition for civil engineering structures, products and materials, is the light weighting properties. Because of the added advantage of the increased structural and mechanical performance of sulphur polymer cements, compared to ordinary Portland cement compositions, the amount of material required in walls sections within the desired structures, products or materials can to be reduced, possibly facilitated by hollowed or cored sections. The improved structural/mechanical performance can also reduce the required wall section thickness.
Light weighting civil engineering structures, products or materials would provide invaluable in the entire lifecycle carbon emissions of such structures and products, by reducing the need for the amount of materials being deployed within such structures, products or materials, while also benefiting, for example, within reduced load bearing with the added benefit of addressing manual handling constraints on certain construction products and materials, which could duly assist constructors, builders, designers and architects addressing key legislative constraints, such as, Construction Design Management (CDM 2007) and the Health Safety Executive's Better backs Campaign" in compliance with current policy outlined within documents CIS 57 and the Manual Handling Chart (MAC 1992) Another advantage that SPC construction products have over their Portland cement equivalents is their frost resistance properties which are much better than is possible using ordinary Portland cement.
As mentioned SPC can be used to produce hollowed or cored products whilst still retaining a high structural strength. It is appreciated that in applications where products are required to have a high weight, for example sea defence blocks, the blocks can be produced in the form of hollowed or cored bricks. In order to give the bricks the required weight they can be filled with cheaper heavy materials that would * not normally be suitable on their own due to their weaker structural properties. * * S *,* * ** 4. * **.*. * S
