On the causes and solutions of insufficient concrete strength produced by concrete mixing plant

Author: admin Release time: December 17, 2017 Number of visits:

Concrete mixing plant equipment In this paper, the quality of concrete produced is more concerned by users. The quality of the whole construction is directly determined by the quality of the concrete. However, in the actual operation, the quality of concrete is not so perfect, the strength of concrete has high and low. Therefore, it is necessary to analyze the causes of insufficient concrete strength and find out the solutions, so as to fundamentally solve this problem.

The reasons for the insufficient strength of concrete produced by concrete mixing plant are as follows:

1. The metering equipment of the concrete mixing station fails, the concrete mix proportion is improper and the measurement is not accurate. The concrete has large slump and out of control.

2. Problems of raw materials: Cement expired or damped, reduced activity; sand, stone aggregate grading is not good, large voids, large mud content, many impurities, improper use of additives, dosage is not accurate.

3. Manual operation problems: the concrete feeding sequence is reversed, the mixing time is not enough, and the mixing is uneven.

After finding out the cause of insufficient concrete strength, corresponding solutions should be taken

1. It is necessary to strengthen the maintenance of the metering equipment of the concrete mixing station, ensure the accurate feeding and control the slump of the concrete mixture out of the machine.

2. Looking for excellent raw material suppliers. Cement shall be provided with factory certificate, fresh without caking, and expired cement shall be used only after passing the test. The particle size, gradation and mud content of sand and stone shall meet the requirements. The mix proportion of concrete shall be strictly controlled to ensure accurate measurement. Concrete shall be mixed in sequence to ensure mixing time and even mixing.

3. Strengthen the concrete batching plant The skill training of operators ensures the orderly input of raw materials to produce ideal concrete.
