Problems solved by technology

[0002] Since our country learned the application of concrete blocks from abroad, it has been rapidly promoted in China in the past few years. my country is a country with a large population. With the rapid economic development since the reform and opening up, the rise of real estate and other construction industries, concrete prefabricated blocks have been widely used. Demand The quantity remains high, and the traditional prefabricated concrete blocks are not environmentally friendly, which brings great pressure to the environment, and has many problems such as large self-weight, low tensile strength, and easy development of cracks.

Abstract

The invention discloses a green lightweight tensile bamboo reinforced concrete precast block. Raw materials of the concrete precast block comprise bamboo sheet fibers, jute fibers, kraft paper, broken stones, recycled concrete, fly ash, perlite and phosphate cement. The green lightweight tensile bamboo reinforced concrete precast block produced in the invention has the advantages of light weight, large tensile strength, great reduction of the self-weight and the cracking probability of walls built by using the concrete precast block and the cracking probability of pavement bricks, good heat insulation property and good noise prevention performance. Materials used in the invention are more environmentally-friendly and economical than traditional brick materials, so the demand for clay is reduced, and the fertile land is protected. Waste concrete is reused, so resources are reasonably used.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and in particular relates to a green lightweight tensile bamboo-reinforced concrete prefabricated block. Background technique [0002] Since our country learned the application of concrete blocks from abroad, it has been rapidly promoted in China in the past few years. my country is a country with a large population. With the rapid economic development since the reform and opening up, and the rise of real estate and other construction industries, concrete prefabricated blocks are widely used. Demand The quantity remains high, and the traditional prefabricated concrete blocks are not environmentally friendly, which brings great pressure to the environment, and has many problems such as large self-weight, low tensile strength, and easy development of cracks. Therefore, be badly in need of a kind of light weight, high tensile strength, the concrete prefabricated block that can greatly re...
