What are the Factors Affecting Workability of Concrete?
What are the Factors Affecting Workability of Concrete?

Water/cement ratio is one of the most important factor which influence the concrete workability. Generally, a water cement ratio of 0.45 to 0.6 is used for ,good, workable concrete without the use of any admixture. Higher the water/cement ratio, higher will be the water ,content, per volume of concrete and concrete will be more workable.

18/1/2016, · Sand accumulation inside the tubing just above the pump is a common problem. It leads to increased pump discharge pressures, reduced fluid rates, and in severe cases, increased potential for sudden pump failure. Sand buildup occurs when the produced-fluid stream cannot carry all the sand up the tubing to surface.
