Abstract

The invention belongs to the field of building materials, and particularly relates to foam concrete and a preparation method thereof. The foam concrete is prepared from the following raw material components in parts by weight: 70-90 parts of cement, 3-5 parts of perlite, 8-10 parts of attapulgite, 5-8 parts of anti-cracking fiber expansion agent, 3-5 parts of light calcium carbonate, 5-10 parts ofactivated sludge, 4-6 parts of natural latex, 0.1-0.3 part of foaming aid, 1-3 parts of surfactant, 0.3-0.5 part of a foam stabilizer and 30-35 parts of water. The foam concrete prepared according tothe preparation method is high in volume stability, does not crack in setting and hardening, is high in water resistance and low in heat conductivity coefficient, realizes integration of light weight, high strength, heat insulation and fire protection, and belongs to an environment-friendly heat-insulated energy-saving material.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a foam concrete and a preparation method thereof. Background technique [0002] With the vigorous implementation of my country's building energy-saving policy, the materials used in modern buildings are required to have properties such as light weight, high strength, heat preservation, heat insulation, waste utilization, and energy saving. Foamed concrete, as a new type of building material, possesses the above-mentioned properties and is widely used in modern construction projects. [0003] At present, lightweight aggregate concrete has been widely used in industrial and civil buildings and other projects to reduce the weight of structures, improve the seismic performance of structures, save material consumption, improve the efficiency of component transportation and hoisting, reduce foundation loads and improve building functions (insulation insulation) heat insul...
