Problems solved by technology

[0003] With the rapid development of social economy and ceramic industry, ceramic industry waste is increasing day by day, which not only causes great pressure on the urban environment, but also limits the development of urban economy and the sustainable development of ceramic industry; The relatively low degree of utilization and the shortage of funds have resulted in a large amount of waste slag occupying cultivated land and polluting water and air. According to incomplete statistics, the annual output of ceramic waste in the country is estimated to be about 10 million tons. Such a large amount of ceramic waste is no longer simply landfilled. The problem that can be solved, and the landfill of ceramic waste not only consumes manpower and material resources, but also pollutes the groundwater quality, turning waste into treasure, and turning ceramic waste into resources has become a top priority for science and technology and environmental protection departments

preparation example Construction

[0033] The invention provides a preparation method of self-compacting concrete prepared by using modified ceramic polishing powder, which comprises the following preparation steps:

[0034] (1) Weigh each raw material: Weigh cement, modified ceramic polishing powder, fly ash, coarse aggregate, artificial sand, water and polycarboxylate high-performance water-reducing agent by a certain number of parts by weight;

[0035] (2) Mix the coarse aggregate and artificial sand and stir evenly to form mixture A; mix cement, modified ceramic polishing powder and fly ash and stir evenly to form mixture B; mix polycarboxylate high-performance water reducing agent and After the water is mixed, stir evenly to obtain mixed solution C;

[0036](3) Pour mixture A and mixture B into a mixer and stir for 20-30 s, then add mixed solution C and stir for 180-240 s to obtain self-compacting concrete prepared by using modified ceramic polishing powder.

[0037] The formula of the self-compacting con...

Embodiment 1

[0047] In this embodiment, in parts by weight, each raw material composition includes: 300 parts of cement, 150 parts of modified ceramic polishing powder, 80 parts of fly ash, 900 parts of coarse aggregate, 780 parts of artificial sand, 175 parts of tap water, polycarboxylate 7 parts of acid superplasticizer;

[0048] The specific preparation process of the modified ceramic polishing powder is as follows:

[0049] The ceramic polishing powder is ball-milled to a specific surface area of ​​830m by an omnidirectional planetary ball mill. 2 / kg ceramic polishing fine powder; transfer the ceramic polishing fine powder to an ultrasonic cleaning machine, ultrasonic for 1.5h, clean and dry; the cleaned and dried ceramic polishing fine powder is then soaked in 9600g of coupling agent dilute solution For 0.5h, drop 10g of cellulose ether dilute solution and 2g of silicone antifoaming agent, stir for another 1h, filter and dry to obtain modified ceramic polishing powder, which is stor...

Embodiment 2

[0058] In this embodiment, in parts by weight, the composition of each raw material includes: 320 parts of cement, 135 parts of ceramic polishing powder, 75 parts of fly ash, 920 parts of coarse aggregate, 770 parts of artificial sand, 170 parts of tap water, high polycarboxylate 6 parts of performance water reducing agent;

[0059] Among them, the specific preparation process of the modified ceramic polishing powder is as follows: the ceramic polishing powder is ball-milled by an omnidirectional planetary ball mill to a specific surface area of ​​800 m 2 / kg of ceramic polishing fine powder; transfer the ceramic polishing fine powder to an ultrasonic cleaning machine, ultrasonic for 1.5h, clean and dry; the cleaned and dried ceramic polishing fine powder is then soaked in a dilute solution of coupling agent for 0.5 h, dropwise into the dilute solution of cellulose ether and organic silicon defoamer, stir for another 1 h, filter and dry to obtain modified ceramic polishing pow...

Abstract

The invention relates to the technical field of building materials, in particular to a self-compacting concrete prepared by using modified ceramic polishing powder and a preparation method thereof. The self-compacting concrete includes the following raw materials: cement, modified ceramic polishing powder, fly ash, coarse aggregate, artificial sand, water and polycarboxylate superplasticizer; the modified ceramic polishing powder is made of ceramic polishing powder The powder is obtained by soaking treatment in coupling agent solution and soaking treatment in coupling agent solution added with cellulose ether and organosilicon antifoaming agent in turn; the specific surface area of ​​the ceramic polishing fine powder is 800-830 m 2 / kg. The self-compacting concrete mixed with modified ceramic polishing powder can effectively improve the compactness of the concrete, and can also improve the fluidity and water retention of the self-compacting concrete. It can effectively solve the problem of shortage of mineral admixture resources.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a self-compacting concrete prepared by using modified ceramic polishing powder and a preparation method thereof. Background technique [0002] Concrete generally refers to a mixture of cement as the main gel material, mixed with water, fine aggregate and coarse aggregate in appropriate proportions and uniformly stirred. Due to the need to use a large amount of mineral admixtures in the preparation process of concrete, the resource of mineral admixtures has become increasingly scarce. Therefore, it is a challenge to find substances that can replace mineral powder and fly ash to prepare concrete in the field of concrete preparation technology. important question. [0003] With the rapid development of the social economy and ceramic industry, the increasing number of wastes from the ceramic industry has not only caused huge pressure on the urban environment, but also lim...
