It is necessary for Zhongke Jufeng concrete mixer: Although there is an automatic metering device for the metering concrete mixer, the use of loader feeding cannot be ignored. Because the loader bucket is large, the batching bucket is small, and there is no baffle, sand and stone will be mixed in the loading process, resulting in inaccurate measurement, affecting the pumpability and strength grade of concrete, and easy to cause pipe blockage. The solution is to increase the ratio of cement to sand, which increases the cost. The mixing time of pumping concrete with double mixing technology shall not be less than 120 seconds. Necessary matters shall be carried out by machinery, but they can not be achieved in actual operation, which will reduce the workability and pumpability of concrete and easily block the pipeline. Pouring concrete is a kind of heterogeneous material. In practice, stone cutting points are often caused along the concentrated feed at a specific point, while cement mortar or floating mud in other areas are used to meet the design strength of concrete mixing and some areas, some of which do not reach the design strength, which solves the lack of strength and increases the amount of cement.
1. Cost control of other production costs: Based on the correct handling of raw material accounts and actual labor costs, the departments and relevant personnel of the project department shall, according to the division of business, Timely, accurate and complete accounting of all other expenses in the specific production process (including: depreciation, amortization and maintenance of mixing plant equipment, temporary facilities, rental of equipment, water and electricity expenses, concrete quality inspection expenses, etc.), and timely submit invoices and documents listed in the current concrete production cost to the financial department. Finally, the control of concrete mixing current can not be settled or the settlement cost is insufficient. The relevant departments and personnel are responsible for providing the information according to the contract price and the actual use (degree of water and electricity or mechanical shift) cost accrual, and submitting it to the financial department in the current concrete production cost to ensure the integrity and accuracy of production cost accounting.
2. Accurate control of material cost: during the accounting period (quarter) of the concrete mixer, the material Department of the project department shall specify the quantity of materials easy to measure and distribute. According to the principle of "when to use and when to record", fill in the material list according to the actual consumed materials in time, and enter an expense in the material entry procedure. The mixer cost method is at the end of the quarter, based on the inventory method of the remaining materials.
Curing concrete shall be cured in time after pouring. Early water loss not only hinders the normal growth of concrete strength, but also reduces the ultimate strength of concrete. Therefore, it is necessary to take corresponding measures to ensure the temperature and humidity according to the change of seasons to meet the demand of concrete strength growth.
