Concrete mixing plant raw materials and mixture ratio

For ready mixed concrete batching plant coarse and water and admixtures requirements, haomei can give you some suggestions for this production line. The maximum size of coarse aggregate is no more than 30mm which is appropriate to allow a small amount of an oversized high aggregate incorporation, but no more than 2%, coarse aggregate should be a continuous gradation, flakiness particle content of not more than 10%.

After the proportion of fine aggregate are not less than 15 by through mesh 0.3%. Water-cement ratio control in the 0.4-0.6 range, a slump of 14-16 cm, sand ratio should be 38% to 45% within two hours after the completion of concrete mixing pumping. Deviation is too large concrete slump which shall enter hopper, and water was added to the hopper is strictly prohibited.

These two technical indicators are noted in the concrete contract. Concrete used in cement, water, aggregates, admixtures and construction specifications must comply with the relevant regulations, good alkali-aggregate reaction test, and inspect the factory certificate or test report meets the quality requirements. Mixing ratio, measuring raw concrete construction specifications must comply with the provisions. Concrete strength test block sampling, production, maintenance and testing to meet the "Concrete Strength Inspection and Evaluation Standards" (GBJ107-87) regulations.
