Combining values from the two systems may result in non-conformance with the standard. Topfoam foamed concrete can be engineered to deliver tailored requirements for density and end strengths dependent on project applications. These pre-cast panels have hollow cores to reduce weight and gooves so that they interlock. Standard References. BuildBlock CSI Commercial Specification. Research is still required on some aspects of the properties of foamed concrete - for example there is little published data on its long-term properties. The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. This product specifications document allows the specifier to identify Section 03 19 11, Insulating Concrete Forming, for R-22 or greater walls and their installation and finish. which produces a stable foam. 1.1 This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete. Foam concrete is a very fluid, lightweight cellular concrete fill material, produced by blending a cement paste (the slurry or mortar), with a separately manufactured, pre- formed foam. 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. It is a lightweight material with low density and limited strength in most applications. The material is a lightweight, free-flowing, self-compacting, and highly insulating material. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete. Related Products Technical Specifications Wattsmix Foamed Concrete is a lightweight, highly flowable, limited strength mix, also referred to as Flowable Fill Material. Foamed concrete is a lightweight mixture of a cementitious binder, water, a stable preformed foam, and, possibly, fine aggregates. A lot of people think that all poly foam material is the same, but that just isn’t true. It is generally self levelling, self compacting and may be pumped. However, within the UK, there are no national specifications for foamed concrete nor standard tests for measuirng its workability, strength or other basic engineering properties. 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. Description of equipment and placement methods to verify compliance with specifications. 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. A foamed concrete is described as having an air content of more than 25% which distinguishes it from highly air entrained materials. Foamed concrete (CLC) panels can be used to build partition or non-load bearing walls. 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. They are made from 950 kg/m3 foamed concrete so they have plenty of strength, but due to the hollow cores the overall density of the panel is 633 kg/m3. This foam is then. The compressive strength of foam concrete determined at 28 days, ranges from 0.2 to 10N/mm 2 or can go higher. This report provides a conspectus of foamed concrete: covering its constituents, production, engineering properties and use. Compressive strengths range from 1N/mm 2 to 10N/ mm 2 and wet densities range from 800kg/m 2 - 1800kg/m 2. The density of foam concrete generally varies from 800-1600kg/m3. Foamed concrete is a highly workable, low-density material which can incorporate up to 75 per cent entrained air. Foamed concrete is simple to produce but, at present, there is a need to provide close control during its production and on-site supervision during its placement and curing. The foam used in ReddiForm has a flame spread rating of 15 and a smoke development rating of 125 based on ASTME84-87 tests, well below the code requirements. [8 A.A. Hilal, N.H. Thom, and A.R.
