LIGHT WEIGHT FOAM CONCRETE Light weight concrete is a mixture of cement, water and special foam, which produces a strong a lightweight building material combining good mechanical strength with low thermal conductivity. Thus it could be thought of as a free-flowing, self-setting fill. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Foamed concrete is a lightweight mixture of a cementitious binder, water, a stable preformed foam, and, possibly, fine aggregates. Spray Polyurethane Foam Specifications. Topfoam foamed concrete can be delivered as a base mix to specialist contractors if a lower density is required. [8 A.A. Hilal, N.H. Thom, and A.R. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates. This is accomplished by using the foaming agent in making a standard cellular concrete test batch (see Test Method C796) from which test specimens are cast. The air is created by the introduction of a preformed foam manufactured using Propump Engineering’s custom foaming agent (Propump 26), encapsulating bubbles of 0.3-1.5mm diameter. Both materials have high flowability, low self-weight, minimum consumption of aggregate, controlled low strength, and excellent thermal insulation properties.
