The role of laboratory quality control of concrete mixing plant

In the midst of the actual mixing of concrete, commercial concrete mixing plant quality control laboratory to give full play to the role.

1. ensure the correct Proportioning

Prior to the formal mix, the experimenter should seriously meet tie ratio, ensuring the right mix to avoid human error caused by ready-mixed concrete quality defects. Researchers should also comply with the requirements to test the moisture content of sand, and then adjust the ratio in order to ensure the quality of concrete.

2. the control of slump

Ready-mixed concrete quality or not, only through certain standard curing period can accurate data. Feedback is very lag of commodity concrete and just to produce ready-mixed concrete cannot accurately determine its quality, only to slump to determine its quality is good or bad.

As long as the raw materials used are correct, the ratio is correct, stirred out of slump of commercial concrete slump similar to the laboratory for laser and should pay attention to the slump, slump detailed memory and comparative analysis of safeguards to protect the concrete quality of the product.

In the slump test session, it should also be noted the slump loss, during construction in summer, due to the large evaporation, ready mixed concrete more water loss, poor and vulnerable. In order to facilitate water, many construction workers to take water to ensure a smooth water. But add water to concrete without control, makes the water/cement ratio has changed, commercial concrete strength will change. This requires the experimenter by slump test found slump value of timely and correct responses to the problems, and ensure the quality of concrete.
