Management control of precast concrete plant for sale

Management control of precast concrete plant for sale include raw materials, mix design and control, production, transportation and concrete pumping process control, delivery inspection and other aspects.

1.Mixing ratio design and control.
The mix design of concrete is a manifestation of the strength of a concrete production technology. The mix ratio can be implemented by the construction unit according to the strength requirements and at the same time according to the strength and particle size of the local raw materials. The technical operators of the precast concrete batching plant are strictly in accordance with the cooperation ratio. At the same time, the design of the mix should take into account the difficulty of the construction site. The concrete production should carefully study the mix design according to the problems reflected by the on-site construction unit, and find the law through the test, to make the mix ratio more scientific and reasonable, to ensure smoother construction. The characteristics of concrete are the diversification of materials and the series of strength. According to the cement strength grade, coarse and coarse aggregate size, admixture type, preliminary design of several appropriate intervals of water-cement ratio, series mix ratio test, preparation strength selection. The water-cement ratio corresponding to the strength of different concretes is adjusted and the mixing ratio is adjusted. After the mixing, the workability of the concrete mixture can meet the requirements as the selected mixing ratio, and the mixing ratio can be controlled in each working class. The concrete mixture was extracted once for each concrete mix ratio, and the concrete mix ratio analysis test was carried out.

2.Control of production and transportation processes.
The technical operator will input the construction ratio of the precast concrete plant for sale operation control computer. For each mixing ratio, the test mixture should be tested, the slump of the concrete mixture should be measured, and the cohesiveness and water retention should be observed. Whether the sex meets the requirements, if it does not meet the requirements, it will be adjusted until it is signed and approved by the operators and technicians.

3.Delivery inspection.
After the concrete is delivered to the construction site, in addition to the type, grade and quantity confirmed by the invoice, the delivery inspection shall be carried out according to the regulations. In order to adapt to the changes in conditions, the slump and retardation time of the mixture should be controlled, and measures such as adding a retarder and adding a water reducing agent according to the conditions should be adopted.
