Concrete is no stranger in our life. Concrete is the raw material for making ceramics, ceramic tiles and other articles. In the delivery of concrete, we often find that concrete is transported by small concrete mixer. The mixer can is wrapped in cloth. There's nothing strange about manufacturers. Some users still don't understand why? In fact, there are reasons for this. It has something to do with concrete.
1. The reason why the tank of small-scale concrete mixer needs to be covered with a layer of canvas can coat is mainly used for heat preservation, heat insulation and noise reduction. Especially in the cold north, when the outdoor temperature is relatively low, the concrete temperature in the tank truck can be kept within a certain range for a certain period of time, because once the temperature is too low, it is not conducive to uniform mixing, and if the temperature is too high Low and frozen, can not be used for construction, so it must be covered with a layer of canvas can, play a role in insulation.
2. In the large tank of small concrete mixer truck is the cement concrete being mixed. If the temperature is lower than freezing point, the water will freeze, and can not fully react with cement, resulting in the decline of concrete quality.
3. It can also play a dust-proof role to prevent some dust from falling into the concrete and affect the quality of concrete.
So we need to spread a layer of cloth on the small concrete mixer to prevent the concrete being mixed from freezing. In addition, the cloth can be used for heat preservation. The performance of concrete will decline at low temperature. Especially in winter when using the mixer, don't forget to cover the jar with cloth.
