Mixing station management process:
In order to ensure the quality of concrete production, our mixing station must follow the following procedures:
The production and transportation of concrete shall be managed by the project leader. When the project needs pouring concrete, the site builder will put forward a plan to the project leader, and notify the laboratory at the same time, and the laboratory will provide the actual construction mixture ratio according to the climate of the day. Deliver the mixture ratio to the person in charge of the mixing station (stationmaster), and the stationmaster will organize personnel and equipment to produce concrete in time, and distribute the concrete transportation record form (attached table) to the concrete truck. After the production is completed, sign and recognize the specific issue sheet in time according to the transportation record form.
Mixer operators must produce in strict accordance with the concrete mixture ratio, and make production records of the day. If there is any operator change, make a handover record in time. (Attached to the Handover Record Form)
The stationmaster should fill in the statistics of raw material consumption in time according to the specific production situation of the day.
4) Purchase and sale of materials
1, concrete production and consumption of ground materials and cement.
Consumption of ground materials, cement, etc. Should be based on the production of concrete quantity accounting, and compared with the construction mixture ratio, monthly inventory.
1# mixing station officially produced concrete in May, 20 10, and by February, 20 10/952 cubic meters of concrete had been produced. No.2 mixing station was put into production, so no detailed statistics were made.

2, steel procurement and recipients
The unit price of steel bar in XXXX bid section is low and the unit price of steel bar is high. As far as the steel bars currently entering the site are concerned, the average unit price per ton of steel bars is as high as 1 000 yuan higher than the average unit price in the bidding budget, which is the main component material of the project engineering entity. Therefore, Comrade Luo, the project manager, put forward a refined management system of total project cost control.
Up to now, 288 tons of first-class rebar, 874 tons of second-class rebar and 82 tons of third-class rebar1/kloc-0 have been purchased, with a total amount of11547,000 yuan. See the attached table 1 for details of the procurement, consumption and inventory of steel bars.
3, cement purchase and consumption
Up to now, 4408 tons of 42.5 cement (bulk) have been purchased, with a total amount of 2.38 million yuan and a consumption of 4280 tons.
4. Procurement and consumption of ground materials
Up to now, the cumulative cost of purchasing ground materials is 6.5438+0.0434 million yuan.
5. Oil purchase and consumption

Taking the concrete output in 20 10 as an example, the total output is 1 1952 cubic meters, and the total consumption of 0# diesel oil is 18667.73 liters, so the fuel consumption of each concrete is 1.562 liters, and the concrete consumption is from/kloc-0.
Generally speaking, Mechanical ministry of materials and equipment well controlled the cost of materials and equipment this year, and the actual consumption did not exceed the design quantity with the same progress, and it was able to organize the required materials to enter the site in time according to the construction progress of the project, which achieved the expected requirements. But at the same time, the quality of local materials is not completely satisfactory, so despite the continuous efforts of the mechanical materials department and the laboratory, the quality of materials can not be controlled in the best state, which is what we need to improve in the next year to make the work of the mechanical materials department of the project better.
