Embodiment

[0016] Embodiment ①;

[0017] A nano-plasticized self-compacting anti-cracking concrete consists of 140-155 parts of cement, 100-120 parts of calcium sulfate powder, 320-350 parts of sand, 340-370 parts of gravel, 45-50 parts of fly ash, and 30-50 parts of silicon powder 15-20 parts of self-sealing material, 1.2-1.8 parts of water reducer, 0.9-1.5 parts of defoamer and 140-200 parts of water.

[0018] A preparation method of nano-plasticized self-compacting crack-resistant concrete, which comprises the following steps:

[0019] (1) Mix 140-155 parts of cement, 100-120 parts of calcium sulfate powder, 45-50 parts of fly ash, 30-50 parts of silicon fume, 15-20 parts of self-sealing material, 1.2-1.8 parts of water reducer and defoamer 0.9-1.5 parts press

[0020] The ratio is added to the mixer and stirred for 6-8 minutes to obtain a plasticizer;

[0021] (2) Mix 320-350 parts of sand and 340-370 parts of stones in proportion to obtain aggregate;

[0022] (3) Mix the plastic...

Abstract

The invention relates to nano-plasticized self-compacting anti-crack concrete, which is prepared by mixing 130 to 155 parts of cement, 80 to 120 parts of calcium sulfate powder, 300 to 350 parts of sand, 300 to 370 parts of stone, 30 to 50 parts of fly ash, 10 to 50 parts of silicon powder, 10 to 25 parts of a self-compacting material, 0.8 to 2 parts of a water reducing agent, 0.5 to 2 parts of a defoaming agent and 100 to 200 parts of water. The concrete has the advantages of high self-sealing performance, high setting and hardening speed, high early strength, convenience and quickness in construction, high later compressive strength, low possibility of cracking and crack generation, and excellent working performance and durability.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a nano-plasticized self-compacting crack-resistant concrete. Background technique [0002] The continuous development of the economy has driven the rapid development of the construction industry, and concrete is one of the most used building materials in modern construction projects, and its demand in various buildings has increased by leaps and bounds. According to preliminary statistics, the total sales of commercial concrete in my country in 2019 will reach approximately 2.738 billion cubic meters. To enhance the comprehensive performance of concrete, reduce production costs, improve the service life of concrete to develop. Contents of the invention [0003] In order to solve the problem of low comprehensive performance of the existing concrete, the invention provides a nano-plasticized self-compacting crack-resistant concrete. [0004] The technical solution adopted by the present ...
