Pinus massoniana lamb leaf thermal-insulation cement brick

Abstract

The invention discloses a pinus massoniana lamb leaf thermal-insulation cement brick, which comprises a pinus massoniana lamb leaf filler, natural sand and cement, and is technically characterized in that the pinus massoniana lamb leaf uniformly filling the cement brick is granular, a base ratio of the pinus massoniana lamb leaf granule to the natural sand to the cement is 40:20:20, and the length of the pinus massoniana lamb leaf granule is 1-5 mm. According to the present invention, the pinus massoniana lamb leaf thermal-insulation cement brick has advantages of environmental protection, light weight, material saving, low cost production cost, low use cost, thermal insulation and sound insulation; the problems that combining of the cement brick and the surface mortar is inferior to the combining of the red cement and the surface mortar, cracks are easily generated on the wall surface and the beauty is affected are solved; and the problems that the foams of the foam cement brick is not uniform, the stress is not uniform, and low strength, cracking, water absorption and other disadvantages exist in the application are solved.

Description

technical field [0001] The invention relates to a thermal insulation cement brick, in particular to a masson pine leaf thermal insulation cement brick. Background technique [0002] Masson pine is widely distributed, from Henan and southern Shandong in the north, to Guangdong, Guangxi, Hunan (Cili County), and Taiwan in the south, from the coast in the east, to central Sichuan and Guizhou in the west, all over South China. Generally, it is distributed below the altitude of 600-700m in the lower reaches of the Yangtze River, above about 1200m in the middle reaches, and below about 1500m in the upper reaches. It is the main timber tree species in southern China. High economic value. [0003] Masson pine is not resistant to decay. The difference between heartwood and sapwood is not obvious, light yellowish brown, long longitudinal fissures, long flaky peeling; wood texture is straight, thick structure; resinous, resistant to water and humidity. The specific gravity is 0.39-...

AI Technical Summary

Problems solved by technology

Foamed cement brick is a new type of energy-saving and environmentally friendly building material. Scholars at home and abroad have done a lot of research and development on it, making it widely used in wall materials, but it still has certain problems, such as low strength and cracking. , water absorption, etc.
