Polymer concrete - Chemical launches tentacles based construction

What is polymer concrete?

A characteristic feature of this concrete mix is ​​to add in the manufacture of high molecular weight organic compounds.In fact, polymer concrete - a mixture, wherein the binder part may perform various polyester and other resins: polyurethane, polyvinyl, epoxy, methylmethacrylate and the like, in combination with curing agents, catalysts, solvents and so on.

geopolymer concrete, the composition of which differs from mixtures based on portland cement is used for exterior and interior spaces and buildings, landscaping and repair work, the creation of small architectural forms.It can be used on both horizontal and vertical surfaces, depending on the applied technology and its consistency.

Features geopolymer concrete

This material consists of a mixture of slag, fly ash, water glass, and other components that are added in the correct proportions.Polymerization occurring in the mixture forms a monolith, which physico-chemical properties and technical characteristics superior to ordinary concrete.

geopolymer concrete, also known as polymer or composite, has a number of advantages in comparison with mixtures based on portland cement, namely:

• very high level of adhesion to any surface;
• small period of hardening;
• high permeability;
• high degree of resistance to bending and stretching;
• increased strength and durability;
• resistance to temperature extremes and acid resistance.

Furthermore, this environmentally friendly material has a low specific weight.Perhaps the only drawback of hindering the wide dissemination of this type of concrete is its high cost.But scientists believe that this material for the future of the construction industry.

geopolymer concrete with their hands, you can make only experimental way.Since the material is in the development stage, the exact formula is not freely available.

Features a polymer concrete

most often as additives used PVA water soluble resins and various latexes.PVA used in particular consistency, wherein the polyvinyl alcohol acts as an emulsifier.After drying

mixture crystallized on the surface of the solid film that swells by absorbing water, so the production of concrete moisture not recommended mode.Repeated dry strength polymer becomes the same.

The optimum amount of additives should be established experimentally.The key to successfully obtain quality concrete mix is ​​the right balance of polymers and cement.The optimum amount of the admixture is approximately 20% of the total weight of the cement.

water-soluble resin are introduced into the concrete in small doses - about 2% of the total weight of the cement.The most high-quality mixture is obtained by the addition of the water-soluble epoxy resins and polyamide in conjunction with the polyethylene polyamine hardener.

geopolymer concrete mixtures prepared by analogy with the usual, cement mixtures.To do this you will need a mixer.First, it adds a certain amount of water with cement, specifically designed for polymer concrete.

Portland cement can not be used here, as it has other properties and characteristics.So cement followed in equal parts to fill up the slag and ash.All thoroughly mixed, then added to polymers and the entire composition further stirring until cooked.
