Abstract

The invention discloses waterproof chemical foaming foam concrete, a preparation method and application thereof. The waterproof chemical foaming foam concrete is prepared from the following componentsin percentage by mass: 45-55% of cement, 8-14% of fly ash, 2-5% of mineral powder, 33-40% of water, and 1.2-1.5% of an additive component, wherein the additive component is prepared from the following components in percentage by mass: 8-14% of hydrogen-containing silicone oil emulsion, 0.8-1.5% of polyether modified silicone oil, 83-89.5% of a water reducing agent, and 1.2-2.5% of sodium gluconate. According to the invention, hydrogen-containing silicone oil emulsion can simultaneously play roles of a foaming agent and a waterproof agent, and can be uniformly distributed in foam concrete to form good adhesive force with the foam concrete, so that the prepared concrete is light in weight, gas-permeable and water-resistant, and the durability is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of chemical building materials, and in particular relates to a waterproof chemically foamed foam concrete and its preparation method and application. Background technique [0002] Foam concrete has excellent properties such as sound insulation and sound absorption, light weight and heat preservation, so it is widely used in various aspects such as building energy saving, sound-absorbing materials and structural weight reduction, especially in today's booming prefabricated buildings. . The common preparation methods of foamed concrete are mainly divided into two types. One is to use foaming machinery, mainly a foaming machine, to prepare a foaming agent aqueous solution into foam, and then add the foam to siliceous materials, calcium materials, water and various The slurry composed of admixtures, etc., is prepared by the physical foaming method of foamed concrete after mixing, pouring and curing; the other i...
