1.1 This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete. They concluded that the mixed proportion of foam concrete used in this research could not be used for structural purposes because the 28-day compressive strength of the foam concrete is less than 17.0 MPa. It requires no compaction, but will flow readily from an outlet to fill restricted and irregular cavities, and it can be pumped over significant distances and heights. specifications. Both materials have high flowability, low self-weight, minimum consumption of aggregate, controlled low strength, and excellent thermal insulation properties. These pre-cast panels have hollow cores to reduce weight and gooves so that they interlock. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. The test batch shall conform to the physical requirements prescribed such as density, compressive strength, tensile splitting strength, water absorption and air loss during pumping. Cellular concrete is a mixture of cement, water, and preformed foam. ). Abstract Foamed concrete possesses characteristics such as high strength-to-weight ratio and low density. 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. This report provides a conspectus of foamed concrete: covering its constituents, production, engineering properties and use. Technical Specifications Wattsmix Foamed Concrete is a lightweight, highly flowable, limited strength mix, also referred to as Flowable Fill Material. Foamed concrete, also called cellular light weight concrete is produced by the mixing of Portland cement, sand including or alone fly ash, water and preformed stable foam. The foaming agent being tested shall be used in making test specimens required. Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar.
