Abstract

The building material can be used mainly for partition walls, stay-in-place formwork and insulating elements.
Description
Building material
The invention relates to a building material, mainly for partition walls, stay-in-place formwork and insulating elements, which is made of cement, water, a granular aggregate and other materials (accelerating, foaming, sealing, fireproofing agents, plastic fibres, etc.) used in the construction industry, as necessary, and which is characterized by containing an organic natural or synthetic binding agent. The building material according to the invention is permeable to gases and steam, it has good heat and sound insulating properties, and is water and fire resistant.
Concrete is one of the most important afterhardening building materials. In the past decades several types of light concrete have been developed. Of these, the most widely used types of concrete are those containing porous, granular thermoplastic plastics (e.g.
polystyrene beads, polyurethane foam).
One of the basic problems of the production of light concretes containing granular polystyrene beads is that it is difficult to mix the light plastic particles homogenously with the cement-water mixture. Another important problem is that cement has no or little binding capacity to polystyrene beads in themselves. Therefore the binding capacity is improved by various surface activation methods and by adding various additives.
According to Hungarian patent No. 162 516 e.g. the granules are coated with a paste made of a surface active aqueous plastic dispersion and cement.
According to German patent No. 1961034 the surface of the granules is coated with epoxy resin.
According to Hungarian patent application No. P8402230 a mixture of coal tar pitch, a phenol-free solution of coal tar and epoxy resin is used as a binding agent.
According to Greek patent application No. 1006369 the flexibility of light concrete is improved by the joint application of polystyrene and a polypropylene copolymer.
According to Hungarian patent No. 203 507 sodium metasilicate is used as a binding agent.
According to international patent application No. WO 2009123760 a special structure is formed to improve the stability properties of light concrete by using modified Portland cement containing a shrinkage-reducing agent in an appropriate quantity, polystyrene beads, crushed stone or mudstone, a water-reducing agent and microfibres.
The aim of the invention was to produce a building material (light concrete) having favourable properties, mainly for partition walls, stay-in-place formwork and insulating elements, that can be produced more simply and economically than those known so far.
The set aim was achieved with an organic natural or synthetic binding agent. The invention is based on the recognition that the molecules of the binding agent enclose, „package" the polystyrene and cement granules. Thereby the binding capacity of cement to polystyrene granules increases, and a building material more stable than those known so far can be produced.
The building material according to the invention contains cement, water, a granular aggregate and other materials (accelerating, foaming, sealing, fireproofmg agents, etc.) used in the construction industry, as necessary, as well as an organic natural or synthetic binding agent.
The binding agent is preferably applied in the form of an aqueous emulsion.
The building material according to the invention preferably contains expanded polystyrene beads as a granular aggregate.
The organic synthetic binding agent according to the invention can be applied not only for polystyrene beads, but by means of it light concretes with different parameters can be produced by using other granular aggregates, e.g. plastic, wood, plant parts, seeds, textile, rubber, etc.
In special cases additives generally used in the construction industry, e.g. accelerating, foaming, sealing, fireproofmg agents, plastic fibres, etc., can also be added.
The stability of the building material according to the invention can be influenced by the quality and quantity of the cement used.
The building material contains 180 - 400 kg of cement, 14 - 21 kg of polystyrene aggregate, water and 2 - 4 litres of binding agent per lm .
According to a preferred embodiment of the invention the building material contains 180 kg of cement, 16 - 21 kg of polystyrene beads, 100 kg of water and 2 litres of binding agent.
The building material according to the invention can be produced with the known construction machinery in such a manner that the water and the cement are placed in a tank equipped with a high rpm mixer, the aqueous emulsion of the binding agent is added to them and mixed at 7-800 revolutions/min. The mixture of materials obtained in this way is transferred to another tank containing the polystyrene beads, homogenized, then the mixture of materials is poured into special moulds and allowed to dry for 8-12 hours. After that the blocks are removed from the moulds and stored for 28-30 days. During that time the concrete reaches its final strength. The blocks with dimensions of 0.8 x 1.2 x 3 m are cut to size with a special sawing machine depending on the individual requirements or the intended purpose.
The waste is ground to an appropriate size and placed in sacks. The ground waste can be used e.g. in foundations.
The raw materials are stored in separate silos. The production line can be automated and, in accordance with the predefined program, from the mixing of the raw materials to the loading of the finished blocks on a truck no human intervention is required.
The building material according to the invention has good heat and sound insulating properties, while it is permeable to air, gases, steam, resistant to flowing water and has the appropriate stability. It is especially suitable for partition walls, stay-in-place formwork and insulation. It should also be noted that as it is permeable to air, it is suitable not only for external insulation, but for internal insulation as well. Thus it can be applied for historic or historically significant buildings, where external insulation is not allowed.
Our invention is described in more detail in the following example, without limiting our claims thereto.
Example 1
Material quantities required for 1 m of the building material:
180 kg of CII 32.5 R cement
3 3
1.2 m of expanded foamed polystyrene beads having a nominal density of 14-17 kg/m and a diameter of 3-6 mm
100 litres of water
2 litres of binding agent
The raw materials are stored in separate silos. The raw materials are placed by an automated machine into a mixing tank equipped with a high rpm mixer in the order of water - cement - binding agent, where they are homogenized at 7-800 revolutions/min. The homogenous mixture of materials is transferred from the mixing tank to another tank containing the polystyrene beads, where it is mixed further with the beads, then poured into special moulds with dimensions of 0.8 x 1.2 x 3 m. After drying for 10-12 hours the blocks are removed from the moulds. After further drying for 28 days the finished building material is cut with a sawing machine, placed on pallets and packaged.
The waste is ground and placed in sacks.
