Problems solved by technology

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a new concrete production process, optimize the feeding combination and feeding sequence of concrete preparation, and effectively solve the problem of uneven distribution of powdery materials in concrete, and the mixing of cement and admixtures. Poor capacity and other problems, reduce the internal defects of concrete, improve the strength and quality stability of concrete products, and save more cement consumption than the existing process

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the examples.

[0022] The traditional concrete production process is to put sand, stone, cement, admixture, water and admixtures into the mixer for mixing. Discharge after stirring evenly, the feeding combination and sequence are as follows: figure 1 shown.

[0023] The production process of the present invention strictly controls the feeding, batching, stirring and unloading of various materials according to a certain combination, sequence and time, such as figure 2 As shown, it includes the following steps: (1) Primary batching dry mixing slurry: According to the mixing ratio requirements of concrete of different strength grades, the cement, admixture, expansion agent and other powder materials are measured separately and then unloaded into a special fine powder mixer at the same time. After mixing evenly, unload it into the mixer, add sand and part of water according to the propor...

Abstract

A new concrete production technology consists of four steps of primary material preparation of dry mixed slurry, secondary material preparation of rear additive, stirring and discharging; through the optimization of feeding combination and blanking in concrete production, the problems of non-uniform distribution of powdery material in the concrete, bad compatibility of cement and additive and the like are efficiently solved, the internal defects of concrete are reduced, and the strength and quality stability of concrete products are improved; under the condition of maintaining the same mixing proportion, compared with the concrete produced by the traditional technique, the slump constant of the concrete produced by using the technology in the invention can be increased by more than 20mm, the concrete strength of C30 level can be improved by more than 10%; and under the conditions of maintaining the original strength and unchanging the flowability, more than 15Kg cement and 5Kg water can be saved in each square of concrete with the strength of C30 level.

Description

technical field [0001] The invention belongs to a new concrete production technology and relates to the production and application of commercial concrete. Background technique [0002] Due to its irreplaceable advantages of low price and long service life compared with other materials, concrete has become the most widely used building material in the world. The traditional concrete production process is as follows: cement, admixture, expansion agent, sand, gravel, water, and admixture are measured separately, and then put into the mixer together, after mixing, they are loaded into the concrete tank truck and leave the factory. There are some problems in this process, such as: uneven distribution of powdery materials such as cement, admixtures and expansion agents in concrete, poor compatibility between cement and admixtures, and easy formation of water films and air pockets around stones inside the concrete. The defect of reducing the compressive strength of concrete, the s...
