Abstract

The invention discloses a high-strength foam concrete material for floor heating and a preparation method thereof. The foam concrete material is prepared from, by weight, aluminum silicate cement, chlorinated butyl rubber, polyurethane, phosphogypsum, pulverized fuel ash, fine sand, stainless steel fiber, nano silicon-aluminum powder, calcium sulphate whiskers, sodium aluminate, opal powder, potassium citrate, fumed silica, 2-(3,4-epoxy cyclohexane) ethyl trimethoxy silane, ethyl hydroxyethyl cellulose, a water reducing agent, a foaming agent and water. The foam concrete material has high compressive strength, low water absorption and thermal coefficients, and various performance indicators meet the requirements of the field of floor heating application.

Description

technical field [0001] The invention relates to the technical field of concrete materials, in particular to a high-strength foam concrete material for floor heating and a preparation method thereof. Background technique [0002] Foamed concrete belongs to high-performance concrete and is a cement-based composite material in inorganic non-metallic composite materials. After foaming, foaming agent is added to the slurry made of cementitious materials, admixtures, admixtures and water. It is a light-weight thermal insulation material made by mixing, pouring, and natural curing. Its production process is a mobile liquid phase. After molding, it is mainly a gas phase and a solid phase. It contains a large number of evenly distributed closed pores. Its thermal insulation performance It has good fire resistance and is a new type of building energy-saving material that is environmentally friendly, light in weight, energy-saving and cost-effective. However, foam concrete has defects...
