there is no doubt that cement is one of the most important raw materials in batching plant. Do you have a good mix of concrete? The general operator is in according to instructions on the mix, but this is limited, according to the specific circumstances of the adjustment, otherwise why recruitment of experienced operators, because for many years with batching plant operating experience Of people, according to experience can quickly select the appropriate ratio, reducing the waste of raw materials, saving costs.

1. Cement dosage and transport resistance and concrete pump volume efficiency must be properly the relationship between the cement dosage.If the cement dosage is insufficient, the pumping volume efficiency is lower, conveying resistance increased significantly, and the concrete water retention is very poor, easy bleeding, segregation, and the clogging;If cement dosage is too large, can make the viscosity is too large, concrete conveying resistance increases, but the efficiency of the pumping volume changes.

2. With the same particle size, graded pebble aggregate and gravel aggregate compared to the larger amount of cement concrete concrete. For fine aggregate, the use of artificial broken sand than natural sand and cement.

3. Pipe diameter is smaller, the longer the pipeline, the demand of concrete fluidity, lubricity, the higher the water retention, so the cement dosage should be increased.
