Boron mud/loess ceramsite concrete hollow insulation block and preparation method thereof

Abstract

The invention discloses a boron mud/loess ceramsite concrete hollow insulation block and a preparation method thereof. The block is prepared from the following raw materials by weight: 125 to 145 parts of ordinary Portland cement grade 42.5, 540 to 580 parts of stone chippings, 28 to 32 parts of boron mud, 12 to 16 parts of loess, 8 to 12 parts of paper pulp waste liquid, 3 to 5 parts of straw ash, 4 to 6 parts of light calcium carbonate, 20 to 30 parts of soluble glass, 8 to 12 parts of straw powder, 3 to 4 parts of a foaming agent, 1 to 1.5 parts of foots, 2 to 3 parts of an asbestos fiber, 0.6 to 1.2 parts of a redispersible latex powder and 160 to 210 parts of water. The boron mud/loess ceramsite concrete hollow insulation block produced in the invention has the advantages of high strength, low density, good heat insulation performance, good impact resistance, small possibility of water absorption, fire resistance, flame retardation, good weatherability, environment-friendliness, energy conservation and the like and has great market space and development prospects in the application field of building energy conservation in China.

Description

technical field [0001] The invention relates to a boron mud / loess ceramsite concrete hollow thermal insulation block and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Wall materials are an important part of building envelopes. With the promotion of building energy conservation and the continuous improvement of people's demand for living environment comfort, wall insulation materials have attracted more and more attention. At present, the widely used wall materials mainly include concrete blocks, aerated concrete blocks, and sintered porous bricks. When ordinary concrete hollow blocks are used for thermal insulation and energy-saving external walls, the thermal insulation and energy-saving effect is poor. In use, composite and efficient thermal insulation materials must be attached to the inner or outer surface of the wall, which is costly and difficult to construct; Due to its good thermal insulation performance, h...

Problems solved by technology

When ordinary concrete hollow blocks are used for thermal insulation and energy-saving external walls, the thermal insulation and energy-saving effect is poor. In use, composite and efficient thermal insulation materials must be attached to the inner or outer surface of the wall, which is costly and difficult to construct; Due to its good thermal insulation performance, high refractoriness, and low density, the block is widely used in the inner partition wall of the frame structure, but its water absorption rate is rela
