Factors Affecting Workability Of Concrete

workability of concrete - types and impact on concrete,workability of concrete can be classified into 3 types as follows. 1. highly workable concrete. highly workable concrete is very easy to mix, pour, consolidate due to the high water content in mixed concrete. transportation and placing of concrete can be a bit difficult due to the high amount of water present in the concrete mixture..all about workability of concrete - structural guide,a workable concrete is a must to do construction work without much difficulty. therefore, it is much important to study the factors affecting workability of concrete. factors affecting workability of concrete. water cement ratio; mix proportions; size of the aggregates; shape of the aggregates; grading of aggregates; surface texture of aggregates.
