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.
Advice: One of the most common errors made when hand mixing concrete is adding too much water. Add a little water each time, the mix will suddenly be at the right consistence. By keeping part of the dry mix to one side, this can be added into the heap if it does appear to be too wet.
