Concrete is one of the most widely used materials in construction engineering, mainly composed of cement, aggregate, sand, water, etc. At the construction site, concrete can be divided into two types: commercial concrete and ready-to-mix concrete according to different use requirements and site environment. Commercial concrete is concrete that is produced on a large scale by concrete manufacturers and mixed according to standard proportions, and is usually transported to the construction site for direct use. Ready-to-mix concrete is concrete that is configured and mixed on site at the construction site. Concrete is an indispensable material in construction projects, and its performance is directly related to the quality and performance of the project. The following is a detailed introduction to the difference between commercial concrete and ready-to-mix concrete.
1.The way of production is different.
Commercial concrete is manufactured in a concrete production plant, and its production process is screened and mixed many times to ensure that the concrete quality meets the standards. In contrast, ready-to-mix concrete is made by on-site proportioning and mixing at the construction site. There are a variety of factors that need to be considered when making concrete on site, such as weather, environmental conditions on the construction site, etc., which can affect the quality of the concrete.
2.The raw materials are different.
The raw materials of commercial concrete and ready-to-mix concrete are also different. The raw materials of commercial concrete are relatively uniform, usually made of cement, aggregate, sand, water, etc. in accordance with the standard ratio. Ready-to-mix concrete, on the other hand, is proportioned and mixed on site, and its raw materials are sometimes affected by the environment and site conditions, such as weather factors, road traffic conditions, etc.
3.Concrete quality is different.
Due to the different production processes, the quality of commercial concrete is relatively stable. Due to the manufacturer's repeated screening and mixing, the quality of the commercial concrete meets the standards and is stable. The quality of ready-mixed concrete may be affected by environmental factors and human factors, such as improper proportioning and uneven mixing, resulting in unstable concrete quality.
4.The scope of use is different.
Commercial concrete is mainly suitable for large-scale construction projects and occasions that require a large amount of concrete. Due to the large scale of production of commercial concrete, a large amount of concrete can be produced in a short time, so it is suitable for the use of large-scale construction projects. Ready-to-mix concrete, on the other hand, is mainly suitable for small construction projects and occasions that require high flexibility. Because the ready-to-mix concrete can be proportioned and adjusted on site according to the actual needs, it is suitable for the use of small construction projects.
5.The production efficiency is different.
The production efficiency of commercial concrete is relatively high. Since it is manufactured in a concrete manufacturer, it can produce a large amount of concrete in a short time, which is suitable for occasions that require a large amount of concrete. Ready-to-mix concrete, on the other hand, needs to be proportioned and mixed on site, and its production efficiency is relatively low, which is suitable for small construction projects and occasions that require high flexibility.
The ** of commercial concrete and ready-mixed concrete varies depending on the region, quality and other reasons. Generally speaking, the ** of commercial concrete is relatively high, because it is manufactured in concrete manufacturers, and factors such as production costs and transportation costs need to be considered. The ** of ready-mixed concrete is relatively low, because it is made by on-site proportioning and mixing at the construction site, and the production cost is relatively low.
Specifically, the ** of commercial concrete usually fluctuates according to market supply and demand, quality and other factors. In some large cities or economically developed areas, the ** of commercial concrete may be higher. The first grade of ready-to-mix concrete is relatively stable, and generally does not fluctuate significantly.
