In the construction process, generally need to use a lot of concrete, but there are many kinds of concrete on the market, such as ready-mixed concrete, commercial concrete and so on, many people are not clear, so what is called ready-mixed concrete? The following and Xiaobian together to see it.

What is ready-mixed concrete
1, the so-called ready-mixed concrete is actually refers to the mixing station after measuring the proportion of cement, aggregate, admixture, water, materials such as mineral admixtures fully mixing together, and sell them to the construction team, and then use truck within the prescribed time, transportation to the scene of the construction of a concrete mixture.

2, ready-mixed concrete is generally sold as a commodity, so it is one of the commercial concrete. In the transport of ready-mixed concrete, it is generally necessary to use tower cranes or trucks to carry out horizontal or vertical transport on the construction site and floor.

3, ready-mixed concrete from out to pouring and tamping this period of time is generally can be properly controlled, when the temperature is relatively high, mixing personnel can slow down the speed of the material, so that even when pouring and tamping will not lead to high temperature concrete temperature.

4. When mixing ready-mixed concrete, 350 or 500 type mixer is generally used for mixing, so the amount of mixing will be less each time. In the process of mixing ready-mixed concrete, it is necessary to use while mixing, and the time from feeding to pouring is controlled in a very short time, so the slump is generally relatively small.

5, ready mixed concrete used by the material and distribution will be better, so the compactness and plasticity of self-mixed concrete will be better. However, the strength of ready-mixed concrete is not very stable, because when mixing ready-mixed concrete, it is generally affected by the artificial and material of each kind of weight, so that the strength of each mixing concrete uneven phenomenon, so the strength of ready-mixed concrete is not very stable.

The above is a detailed introduction of what is called ready-mixed concrete, hoping to help you answer the doubts in your heart. Ready-mixed concrete is generally sold as a commodity and needs to be transported to the construction site within a specified time using transport vehicles, so it is also one of the commercial concrete.
