Question

Polymer concrete is most suitable for 
1. Sewage disposal works
2. Mass concreting works
3. Insulating exterior walls of an air-conditioned building
4. Road repair works

Answer 1

Correct Answer - Option 1 : Sewage disposal works

Polymer concrete: Polymer concrete is a composite material in which the aggregate is bound together in a matrix with a polymer binder. The composites do not contain a hydrated cement phase, although Portland cement can be used as an aggregate or filler.The impregnation of monomer and subsequent polymerisation greatly improves some properties of the concrete.

Properties:

1. High tensile, flexural, and compressive strengths
2. Resistance to oil, grease, abrasion and good adhesion to most surfaces
3. Good long-term durability with respect to cycles of freezing and thawing
4. Low permeability to water and aggressive solutions
5. Light weight.

Applications:

1. Most suitable for sewage disposal works because of its high sulphate and acid resistance properties.
2. In the production of prefabricated elements and prestressed concrete.
3. In ferro-cement products and marine works.
4. In nuclear power plants and industrial applications.
