M25). We all know that water cement ratio will directly affect the strength of concrete. Either it increases the strength if used in correct proportion or decrease it. But have you ever think about it . If we need to calculate Water quantity for concrete, first find the cement content for the volume. If we Assume the required cement.
Dense and homogeneous concrete. II. Economy a) Economy in cement consumption. It is possible to save up to 15% of cement for M20 grade of concrete with the help of concrete mix design. In fact higher the grade of concrete more are the savings. Lower cement content also results in lower heat of hydration and hence.
