A concrete mixing plant is a joint installation for the central mixing of concrete, also known as a concrete pre-production plant. In large construction projects, a large amount of concrete is required and the advance mixing of concrete mixing plants can significantly increase the efficiency of concrete production and allow the production of large quantities of concrete of the same quality at the same time. The management and cost control of a concrete mixing plant is related to the quality of the construction work and the final cost of the construction work, so it is necessary to improve the management and maintenance of the concrete mixing plant.
1. The importance of managing concrete mixing plants
Due to the wide range of factors affecting the quality of concrete, special attention needs to be paid not only to the admixtures and the proportion of water and ash added to the concrete when mixing, but also to the maintenance of the concrete after it has been poured. A concrete mixing plant is where the various raw materials for concrete, including cement and ash, water, sand and aggregates, are mixed according to the mix list issued by the test laboratory. The concrete mixing plant is equipped with complete mechanical equipment and mature technology to mix the raw materials for the production of concrete on a large scale, which greatly increases the production speed of concrete.
The management and planning of a concrete mixing plant is conducive to improving the efficiency of the plant, the service life of the plant and the use of the various concrete materials. In addition, the management of the concrete mixing plant facilitates the production of stable concrete, which facilitates the maintenance of the concrete after it has been placed. The stable chemical nature of the concrete also has an impact on the hydration within the mass concrete, which reduces the risk of cracking of the mass concrete.
2. Issues to be noted when carrying out concrete mixing plant management
Before the concrete mixing plant is set up, during the concrete mixing process and during maintenance are all issues that should be faced in the management of a concrete mixing plant. The management of a concrete mixing plant can be carried out under the following conditions.
2.1 Management at the time of setting up a concrete mixing plant
Before setting up a concrete mixing plant, careful consideration should be given to the location of the plant, which should be conveniently located by the roadside, as well as to the water sources in the surrounding environment, in order to reduce the cost of transporting raw materials to the plant and to reduce transport costs. Secondly, the mixing equipment should be adjusted according to the construction needs and suitable mixing equipment should be selected.
2.2 Daily management of the concrete mixing plant
During the work of the concrete mixing plant, there should be staff to ensure that the relevant materials and tools are placed in an orderly manner. The aim is to ensure that the passages around the mixing plant are unobstructed and to reduce the time costs incurred by transport vehicles staying in the mixing plant. In terms of personnel management, the mixing plant needs to be equipped with relevant management and technical personnel but also needs to control extraneous personnel from entering the mixing plant to avoid safety problems. In addition, there is a need for maintenance personnel to overhaul and maintain the plant equipment in accordance with the regulations. As most of the equipment in a concrete mixing plant is of high value, it is important to monitor and repair the equipment to improve its service life and productivity.
2.3 Daily maintenance of the mixing plant
There are several aspects that need to be done in the daily maintenance of a concrete mixing plant. Firstly, the cement slurry, sand and gravel materials in the tank should be cleaned up in time after the production of the concrete mixing plant so as not to affect the future work. Secondly, monitor the operation of the equipment, check the wear and tear of the blades, check the wear and tear of electrical contactors, bolts, belts and other parts, and carry out relevant operations on the parts that need to be replaced and maintained. Thirdly, let the relevant operation and management personnel establish the awareness of safe production, to reduce the risk of accidents.
The cost of a concrete mixing plant consists of several parts, including the labour costs of management and technical personnel, equipment costs, raw material prices, transportation costs, etc. The cost components affecting a concrete mixing plant can be considered from three aspects: before, during and after production, and thus the cost of a concrete mixing plant can be controlled from various details.
3.1 Cost control before production
The costs of a mixing plant before ready-mixed concrete mainly relate to the cost of labour at the plant as well as the cost of equipment. Concrete mixing plants are selected according to the specific needs of the construction project, based on the use of the concrete to be produced, the number and type of mixers and the supply capacity. When staffing a mixing plant, a reasonable management system can be developed to improve the utilisation rate of staff and control the labour costs of workers, and different settlement methods can be adopted for different projects to improve the efficiency of workers and reduce labour costs. In addition, the cost of a concrete mixing plant can be further reduced by selecting the location of the plant to reduce the transportation cost of raw materials such as aggregates and water. At the same time, the cost of concrete can be controlled by comparing the unit prices proposed by multiple raw material suppliers and selecting the right supplier with the right price.
3.2 Cost control at the time of production
Cost control at the time of production is mainly a matter of raw materials and their proportioning. Before mixing, it is necessary to ensure the scientific nature of the concrete ratio to ensure the quality and economy of the concrete. Secondly, the raw materials purchased at the site should be controlled to ensure the quality of the raw materials.
The right cement should be used in the operation to avoid high cement temperatures when entering the tank, otherwise the cement will clump together and affect the mixing effect and the quality of the cement. When adding other conditioning agents, attention should be paid to the quality and order of addition to avoid lumping and high temperatures inside the concrete caused by irregularities in the addition, and to ensure the quality of the concrete.
3.3 Cost control after production
The main aspect of cost control after production is the transport of concrete. In the concrete mixing process, attention should be paid to the mixing speed of concrete, control the mixing speed and loading speed of concrete, avoid the waste of resources due to idle equipment, and ensure that equipment and labour resources are fully utilised. In addition, we should also strengthen the material accounting work, make detailed statistics on the use of materials and the purchase of materials to minimise the waste of raw materials and reduce the cost of concrete.
As an essential building material in the process of building construction, the quality of concrete determines the structural quality of a whole building, but if you want to ensure the quality of concrete, then you need to focus on the construction and management of concrete mixing plant for reasonable planning. In the entire production process of a concrete mixing plant, management and cost control are the focus of the planning and construction. They determine the input-output ratio of the entire concrete mixing plant, because only if the input-output ratio reaches a certain value can the quality of the product be guaranteed. The whole construction process is very important.
