Abstract

The invention provides truss type ceramsite foam concrete and a preparation method thereof. The truss type ceramsite foam concrete is prepared by filling a ceramsite truss structure material with a foam filling material and curing the foam filling material, wherein the ceramsite truss structure material comprises components in percentage by mass in a formula of the truss type ceramsite foam concrete as follows: 7%-18% of a cementing material, 40%-60% of ceramsite, 3%-15% of fine aggregate, 0%-0.3% of a water reducer and 3%-10% of water; the foam filling material comprises components in percentage by mass in the formula of the truss type ceramsite foam concrete as follows: 10%-20% of a cementing material, 0.05%-5% of an activator, 0.02%-0.3% of a foaming agent, 0%-0.3% of a water reducer and 5%-12% of water. The truss type ceramsite foam concrete simultaneously has higher bearing capability and excellent thermal insulation performance.

Description

Technical field [0001] The invention relates to a new wall material in the field of building materials, in particular to a grid-type ceramsite foam concrete and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of wall materials, more and more functional wall materials for the purpose of energy saving and heat preservation have appeared in the society. Among them, foam concrete and polystyrene foam board ( EPS board), concrete hollow block, ceramsite block, sintered porous brick, etc. Thermal insulation wall materials can be divided into organic thermal insulation wall materials and inorganic thermal insulation wall materials according to their materials; they can be divided into thermal insulation wall materials and structural thermal insulation wall materials according to their use. [0003] Organic thermal insulation wall materials generally have low density and good thermal insulation performance, but low compressive s...
