Abstract
The invention discloses a preparation method of an active glass powder mixture material and belongs to the field of building materials. In the invention, active glass powder in the grade of 50 [mu]m is used for replacing cement in a concrete mixture material, and with proper additives, concrete satisfying corresponding standard is prepared by means of material blending of the active glass powder with other sand, pebble and water reducing agents according to a reasonable ratio. The method can consume domestic waste glass at large quantity with the addition amount being 1:(3-7), so that performances of concrete are improved, thereby turning the waste glass into useful resources. The method can save cost and protect environment. Strength of the prepared concrete can satisfy national standard completely and satisfy the requirement in C15-C40 grades. The concrete is excellent in durability. The preparation method is simple, is low in cost, allows large-scale production at various regions and different weather conditions, and is greatly improved in operability and reduced in enterprise cost.
Description
Technical field
The invention belongs to building material technical field, specifically a kind of preparation method of activity glass powder compound.
Background technology
Concrete is the base mateiral of society widespread use, and its development be unable to do without the progress of society, and the civilization degree of society determines concrete development degree.Building trade and building material industry have been listed in the mainstay industry in this century.From the not destroyed prerequisite of physical environment of making rational use of resources and the energy, the protection mankind depend on for existence, how to make concrete can meet the strategy of Sustainable development, development GHPC is the requirement in epoch, is also the certainty of concrete development.Cement is concrete important raw and processed materials, therefore, reduces the CO that manufacture of cement is brought
2discharge, improves the consumption of industrial residue, improves concrete weather resistance, and extend the life-span of buildings, the road walking the green of Sustainable development is concrete developing direction and future.In China, the scrap glass in annual city, ground is about 450-750 ten thousand tons, and every year in increasing trend, the scrap glass 600,000 tons that Taiwan is annual, Hong Kong produces nearly 120,000 tons of cullet every year.Nearly 90% be transported to stacking and fill out buried regions and discard, processing costs is quite high, only reclaims the expense of a link just up to 300 yuan/ton.Owing to polluting, the reasons such as cost and color complexity, the glass only having small part to reclaim can for the production of new glass, and this just causes a large amount of scrap glasses and cannot recycle, define the waste of huge social resources, acid test be also form to day by day rare land resources.Thus glass waste is dealt carefully with imperative.
Glass is unbodied, and containing a large amount of silicon and calcium, as long as granularity reaches a certain size in theory, will possess pozzolanic activity, even gelling, in concrete, can be used as mineral admixture.And improve concrete performance, and become valuable commodity, be not only conducive to cost-saving, also can protection of the environment, in current harmonious society, there is earth shaking meaning.
Summary of the invention
The object of the present invention is to provide a kind of method simply utilizing glass powder to prepare concrete mixture.Research proves that the glass powder of certain particle size has Pozzolanic feature, and portland-pozzolan cement reaction refers to active SiO
2, active A l
2o
3in isoreactivity component and silicate cement, grog aquation generates Ca(OH)
2reaction, the main Calucium Silicate powder (C-S-H) generating aquation.In order to achieve the above object, the present invention adopts following technical scheme:
(1) by discarded life glass classification removing foreign material, and after glass tap water is cleaned up drying, the block broken into pieces and obtain 3-5cm diameter is put in encloses container, then drop into pulverizer to pulverize, pulverizing number of times is 3 times, and each 30s, obtains glass powder weight ratio and reach more than 90%.
(2) by the glass powder ball milling 30min in step (1), more than 95% is reached to glass powder even thickness degree.
(3) step (2) is obtained glass powder, adopt sizing analysis method, particle size range at 10-50 μm, specific surface area is at 500-800m
2the glass powder of/kg, as one of concrete mixed raw material.
(4) concrete mixture ratio prepares by following weight ratio: cement 0.7-0.8 part, glass powder 0.08-0.12 part, sand 0.8-1 part, gravel pebbles 0.08-0.15 part, water reducer 0.01-0.04 part, water 0.15-0.2 part.
(5) glass powder step (3) obtained and according to the cement in step (4) pour into normal agitation machine stir 2-3 minute, then add sand and stir 1-2 minute again, add again gravel pebbles stir 2-3 minute, finally add water and water reducer stir within 5-8 minute, obtain concrete mixture.
(6) concrete mixture of step (5) gained is prepared into the concrete test block of standard, and takes natural curing method to carry out maintenance.
Glass powder in foregoing invention can be used as concrete gelling material.Be 1:(3-7 with the blended ratio of cement), because in glass, soft silica basic active is higher, Alkali-silica reaction can be there is in concrete, its structure is damaged.But the present invention is the glass powder of particle below 50 μm, and can be evenly distributed in concrete base material, pozzolanic reaction can occur, and thus can not damage.Meanwhile, levigate glass powder can also bring following benefit:
(1) provide a kind of recycling approach of scrap glass, avoid waste, save land resources, decrease scrap glass handling.
(2) glass powder in the present invention partly can replace the cement in concrete, reduces and produces concrete cost, decrease the loss to natural material, can also energy-saving and emission-reduction, meets the theory of the strategy of sustainable development and green energy conservation.Also can improve concrete intensity and workability simultaneously.
(3) the glass powder acquisition methods in the present invention is simple and convenient, and cost is low, is applicable to the scale operation of most of region.
