How many ways are there to mix concrete?

Concrete mixing is the process of mixing cement, coarse and fine aggregates, water and admixtures into a concrete mix of uniform texture and color with a certain degree of fluidity. If the concrete mix is not uniform, you can not get dense concrete, affecting the quality of concrete. Concrete mixing is divided into manual mixing and mechanical mixing. Due to the poor quality of manually mixed concrete, only in a very small amount of work will be used, mechanical mixing is more widely used.
