With the rapid development of economy in our country, the competition among commodity concrete enterprises is becoming more and more intense. Product cost analysis is an important part of enterprise management. Through cost analysis, to find loopholes in enterprise management, provide cost information for enterprise leaders, so as to plug loopholes, reduce costs, develop corrective actions and make the right decisions. The cost analysis of commercial concrete is mainly divided into two parts: first, the cost control of raw materials, and the two is the management cost control of the company.

1 content of the cost of the product

Main material of commercial concrete. Auxiliary material for commercial concrete. Expenditure on various expenses.

1.1 cost control of raw materials: raw materials into the factory. The components of commercial concrete include cement, sand, stone, water, admixture, pumping agent and admixture. For all the raw materials into the factory requirements: raw materials into the factory to work through the company’s real work. After entry into the plant raw materials such as cement, slag and fly ash to enter into the mixing chamber of commercial concrete station within the crew for micro mixing. The factory opened a single weighing weighing room, to eight the next morning to pay Statistics Department, statisticians material classification statistics. In order to make the cost analysis convenient at the end of the month, we should do a lot of work, and we must master the change of the price of the raw material. Regularly check with the suppliers of raw materials for the supply of materials, if there is a difference in quantity, timely search, try not to wait until the settlement of materials check, for their own inconvenience. Raw material consumption. Eight every morning, when the lab technician will shift according to the production plan and raw materials issued a new mix adjustment notice, dispatch room in customer requirements and technical requirements of commercial concrete strength grade under the condition of dispatch and command, with the stirring member according to the dispatch room instruction and the stirring ratio adjustment notice. In order to understand the consumption of raw materials, to achieve the next morning in the statistician mix according to the mixture ratio of the amount of material, calculate the consumption of materials. Of course, the error of manual calculation is very large, the variety of materials supply complementary swap often mix, each concrete mixing plant there are such problems, the solution is to install a set of mixing station management system software, the whole process of computer command and monitoring of production management. Selection of raw materials. A cement. Cement is the main cementing material in commercial concrete. When cement enters the factory, it is necessary to control the quantity of cement and strengthen the storage measures. Cement is a kind of hydraulic cementing material. It is easy to agglomerate and deteriorate. Therefore, should be based on production, in order to meet the continuous production of the situation to ensure that the positions, according to the needs of the use of the advanced factory. Cement manufacturers are more, mainly from the experimental room to investigate the first trial, choose the quality of stable and reliable, affordable prices, but also to ensure the supply of manufacturers. B sand. Sand plays a role of aggregate filling in the commercial concrete, and the quality of the sand has certain influence on the strength and operability of the commercial concrete. The middle sand is generally used, mainly because of the good gradation of the middle sand. Coarse sand will affect the workability of commercial concrete and reduce the pumping capacity of commercial concrete. If the workability of commercial concrete can be met, the coarse sand will be added to the fine powder, and the amount of cement will be increased. Fine sand and coarse sand are disadvantageous to the strength of commercial concrete and are generally not allowed to be used. Therefore, both the quality and cost considerations should be used in accordance with the requirements of sand in the sand. Most commercial concrete mixing plant require sand mixing. First, the cost is low, and two of them can be separated from the river stone. They are used as aggregate in the lower type of commercial concrete. C stones. Pebble plays a skeleton role in the application of commercial concrete, and plays an important role in the strength of commercial concrete. Stones are divided into rivers, rocks and gravel. The surface of the river stone is smooth and the workability of the commercial concrete is enhanced. Therefore, the river and stone are often used as aggregate in the commercial concrete. But because the river stone gradation is not good, low strength concrete, not suitable for high strength, so the strength of commercial concrete under the condition of lower level requirements such as: C10, C15, C20 commercial concrete strength grade, there are no special requirements under the condition of the river stone as the aggregate. High strength commercial concrete, such as C25, is often added to two. Crushed stone is artificially broken aggregate, the aggregate strength is higher than the pebbles, are used for more than C30 commodity concrete. The size of crushed stone used in general commodity concrete is 0.5 ~ 2.5cm, which is good for pumping. The frost resistance and impermeability of goods or other special requirements of the use of the gravel and mud content should not be greater than 1%, clod content should not be greater than 0.5%. D admixture. The admixture of commercial concrete mainly refers to fly ash and mineral powder. Fly ash and slag can significantly enhance the liquidity of commercial concrete, and can reduce the performance of commodity concrete bleeding and segregation. The fly ash can reduce the hydration heat of the large volume commodity concrete, and it is helpful to control the temperature crack. Because the mineral powder itself has certain active effect, mineral powder
