Analysis on Standardization of Material Management in commercial concrete mixing plant

2017-05-02

The quality of the raw material of the commercial concrete mixing plant determines the quality of the concrete. The material management of the commercial concrete mixing plant should be done: to keep the source, the quality is qualified, the quantity is correct, the position is accurate and the supply is guaranteed. Here, Lianhua to analyze the next concrete mixing plant material management rules are what?

Because the same material of different manufacturers have different physical and chemical properties, the experimental department selected material combination is compatible, so the material should be selected once the stability; the other hand, the material short positions, Concrete mix of chaos; the above factors will directly affect the workability of concrete, strength and durability requirements, so the material staff must check the material acceptance: First, to ensure that the source is not chaos, the second is to ensure the quality of qualified before put into use, three Is to ensure that the position is good, the fourth is to ensure that the number is sufficient, five is to ensure that the original documents of various materials collection and proper custody.

For a large volume of concrete components with continuous casting requirements, it is necessary to confirm that all the material requirements are ready for arrival and after passing the test, the material can be prepared for dispatching the material.

Acceptance of sand and gravel material: commercial concrete mixing plant should be sent to the gravel supply yard, for each car gravel material confirmation (in the "waybill" on the sign). When the entry agent is responsible for the audit of each car gravel material, to confirm the source material field is correct, visual specifications, quality qualified, asked the driver to rinse the transport vehicle wheel attached to the soil after weighing, accurately guide the material to the silo Unloading; vehicle back skin, the Secretary of the staff and the receipts together on the invoice to sign, retained a "waybill", the vehicle release.

Cement, admixture, admixture acceptance: response to the car "waybill" specified on the manufacturers, name, variety specifications, label, batch number, product certification to check, correct after weighing, accurately guide the vehicle to the corresponding position Unloading; vehicle back to the skin, the Secretary of the staff and the receipts together on the invoice to sign, retained a "waybill", the vehicle release.

Water: should be drinking water or natural water, are not allowed to use oil, sugar or harmful impurities and other waste water, the use of tap water to consider the standby water to prevent water production caused by shutdown.
