7 Types of Sand Used in Construction - BuilderSpace

Concrete sand consists of granite rock, gneiss, or limestone. This sand has angular granules and works best when mixed with cement. Besides usage in concrete, concrete sand can also be used in bedding pipes. This type of sand is usually crushed in a quarry and filtered severally to remove huge fragments and large rocks.

How Cement, Sand and Aggregate ratios influence Concrete Properties ...

Total Aggregate by cement ratio (A/C) decreases with increase in grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30. Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio.
