ABSTRACT:
Improved polymer bonded concrete is disclosed wherein the amount of polymer binder used may be reduced to amounts as low as 3 to 10% by weight of the concrete. The concrete has however high strength and other improved properties such as high modulus of elasticity, low thermal expansion and contraction, better fire resistance, low shrinkage on curing and the like and also very importantly, the cost is reduced. Preparation of the concrete is disclosed using an in situ polymerization process together with intense vibration of the monomer component-solids mix.
