Quartz Versus Limestone Which sand is better in concrete

Limestone powder or derivatives of it are used to make powdered portland cement Limestone sand which is used in some decorative concrete is created by crushing limestone rocks to make sand Limestone sand is soft enough that the angular edges of the grains can be easily crushed broken and turned to powder 3 Concrete Sand 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
