Xonotlite reinforced and foamed cement and production method thereof

Abstract

The invention discloses xonotlite reinforced and foamed cement which comprises 10-20wt% of xonotlite slurry and 80-90wt% of foamed cement and is produced by uniformly mixing the xonotlite slurry and the foamed cement and then foaming the mixture. According to the invention, by using the xonotlite active slurry is used as a reinforcing material and by combining the inherent characteristics of the foamed cement material, and the xonotlite reinforced and foamed cement with high compressive strength and low heat conduction coefficient is produced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a xonotlite reinforced foamed cement product and a production method thereof. Background technique [0002] Building energy conservation has become an important link in the implementation of energy conservation strategies in China. Building energy conservation is reflected on the wall, which is to insulate the wall enclosure structure. At present, the popular building external insulation materials in China's market are mainly EPS (molded polystyrene board ), XPS (extruded polystyrene board) and PU (polyurethane), in fact, EPS, XPS and PU are all organic insulation materials, the biggest advantage is light weight, good heat preservation and heat insulation, the biggest defect is poor fire safety, It is easy to age, easy to burn, produces a lot of smoke when burning, and is very toxic. Due to the occurrence of many building insulation fire incidents in recent...

[0002] Building energy conservation has become an important link in the implementation of energy conservation strategies in my country. Building energy conservation is reflected on the wall, which is to insulate the wall enclosure structure. At present, the popular building external insulation materials in my country's market are mainly EPS (molded polystyrene board ), XPS (extruded polystyrene board) and PU (polyurethane), in fact, EPS, XPS and PU are all organic insulation materials, the biggest advantage is light weight, good heat preservation and heat insulation, the biggest defect is poor fire safety, It is easy to age and burn, and produces a lot of smoke when burning, and is very toxic. Due to the occurrence of many building insulation fires in recent years, the fire performance of insulation materials has attracted unprecedented attention from all walks of life in the industry.

[0003] Foamed cement insulation board is currently the most ideal insulation material for wall insulation and wall insulation fireproof isolation belt. Its advantages are: no burning, strong adhesion with the wall, no toxic radioactive substances, environmental protection, economy, and easy construction , fast, its disadvantages are: low strength, brittle, poor toughness, brittle, and the flexural strength can only reach above 0.1MPa, which cannot be compared with foam glass, foam ceramics, phenolic foam board, polystyrene particles, polystyrene board, extrusion Compared with wall insulation materials such as boards
