Types of Concrete Mix Ratio Design and their Strengths
Concrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. These mix ratios are decided based on type of construction and mix designs. However, building codes provides nominal and standard concrete mix ratios for ...
What is the Right Water-Cement Ratio for Mix Design?
A right water-cement ratio for concrete design will influence the compressive strength, permeability and the overall durability of the concrete structure. The idea of w/c ratio is that more the value, greater is the water content in the concrete and ...
