Construction Control precast concrete batching plant

1, raw material weighing deviation should meet the specification requirements.

2, priority concrete materials used to heat the water heating method , when the hot water can not meet the requirements of the aggregate should be further heated to ensure the concrete into the mold temperature must not be lower than 5 ℃.

3, plus antifreeze portable concrete batching plant, when antifreeze is powder , the required dosage directly sown in the cement and cement while investing . When the antifreeze liquid formulation should be prescribed concentration of the solution , then according to requirements , preparation of construction solutions , admixtures class should be used once dubbed , mixing time should be extended 1min.

4, preparation, adding antifreeze , you need to hold people accountable and make a record , in strict accordance with the incorporation of the dose required .

5, cement shall not directly heated before use should be placed in greenhouses for storage.

6, mixing concrete , aggregates shall be with snow and ice and frozen groups.

7, should be removed before pouring concrete in the snow and dirt on the template and steel .

8, precast concrete batching plant  transport , pouring , and the entire time interval shall not exceed the initial setting time of concrete, concrete construction segment should be the same continuous casting , and shall, prior to the initial setting of the bottom layer of concrete pouring is completed , transport and pouring concrete containers should be used there insulation measures.
