Mixing of Concrete is a very complex process. For making good quality concrete, we just have to follow some standard process of mixing its ingredients. It just does not up to making concrete, but making good quality concrete is important.. Production of good quality and bad quality of concrete includes the same material, but the proportion and mixing method can be a differentiating factor.

Feb 09, 2017 Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. The main objective in transporting concrete is to ensure that the water-cement ratio, slump or consistency, air content, and homogeneity are not modified from their intended states. Concrete produced from a mixer is required to be transported to the
