Novel light anti-cracking concrete and preparation method thereof

Abstract

The invention discloses novel light anti-cracking concrete and a preparation method thereof. The novel light anti-cracking concrete is prepared from the following ingredients in percentages by weight: cement 22.51%, pottery sand 22.69%, bentonite 20.307%, flyash 16.43%, durafiber 0.097%, a foaming agent 0.083%, a water reducer 0.26%, an air entraining agent 0.056% and water 17.567%. The prepared concrete is light in weight, high in compressive strength and good in thermal insulation property, and is environmentally friendly and energy-saving; a wall structure poured by the novel light anti-cracking concrete can be formed well, and is high in surface perpendicularity and flatness, therefore, processes of plastering and the like of interior walls and exterior walls are omitted, and common quality problems such as hollowing, cracks and leakage caused by plastering are avoided.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a novel lightweight crack-resistant concrete and a preparation method thereof. Background technique [0002] According to the basic national policy of saving resources and protecting the environment, vigorously develop low-carbon, energy-saving, and environmentally-friendly buildings, and change the traditional extensive and labor-intensive production models of bricks, tiles, ash, sand, and stones. [0003] At present, the industrialization level of housing construction in advanced countries is as high as 70%, and the industrialization level of our country is less than 10%, especially in the construction of the main body of the building, the industrialization level is less than 5%, and it still stays in the multi-channel construction process and manual construction in sequence. In terms of the way (that is, the main structure and wall structure of the existing traditional housi...

Problems solved by technology

[0004] In addition, conventional concrete currently on the market is heavy, and its compressive strength, tensile strength, and flexural strength are all very low. Therefore, when using it to build walls, only brick-laying structures can be used, which means that there are technical problems mentioned above. For this reason, foam lightweight concrete has appeared on the market, and adopt this foam lightweight concrete to pour the wall structure, but compressive strength, tensile strength and flexural strength are still low, and the molding surface is rough and needs secondary plastering , the cost is relatively high
