Formula of high workability concrete

Abstract

The invention relates to a formula of high workability concrete, which includes the raw materials including, by weight, 150-300 parts of cement, 40-80 parts of mineral powder, 60-150 parts of fly ash, 800-1200 parts of a fine aggregate, 1000-1500 parts of a coarse aggregate, 150-200 parts of water and 0.2-0.6 parts of cellulose ether. According to the invention, the workability of concrete can be significantly improved, and the concrete slurry is full, has good flowability and is easy to pump and construct.

Description

technical field [0001] The invention relates to the technical field of concrete efficiency enhancement, in particular to a high workability concrete formula. Background technique [0002] With the continuous development of society, the demand for commercial concrete is increasing day by day. After more than ten years of rapid development, commercial concrete has entered a relatively mature stage, and various commercial concrete basically meet the requirements of the project. However, in actual work, we will find that when using pumped concrete, often due to reasons such as poor workability of concrete and unstable sand rate, the pump truck will be blocked, and a lot of time and manpower will be wasted on the construction site and mixing station, which will even affect the quality of the concrete. quality of engineering. Especially low-grade concrete, its workability and pumpability are worse, it is more unstable, and the probability of pipe plugging and explosion is higher....

However, in actual work, we will find that when using pumped concrete, often due to reasons such as poor workability of concrete and unstable sand rate, the pump truck will be blocked, and a lot of time and manpower will be wasted on the construction site and mixing station, which will even affect the quality of the concrete. quality of engineering

Especially low-grade concrete, its workability and pumpability are worse, it is more unstable, and the probability of pipe plugging and explosion is higher. Usually, increasing the sand rate and increasing the cementitious material can improve the above situation, but at the same time it will also increase material cost of concrete
