Density Requirements in Cement, Sand, and Aggregate for better Building Construction
Density is defined as mass per unit of substance volume of a substance i.e. unit weight of that respective substance. Line (p) denotes as symbolic form of Density .It describes as material compactness that means the higher the density of substance more compacted the material is.
Cement Density
1. Concrete density has increased its strength and durability. By doing this process density of cement has got least concern.
2. Cement act as binder in a concrete, knowing its density will be very useful to change the concrete characteristics. The standard density of Cement has 1440kg/m3.
Density of Sand
- Sand comprise in near about 35% concrete volumes. Careful mixing of cement, fine and coarse aggregates, water and admixtures produced to be good quality concrete.
- For the construction use, River sand also known as Natural sand has a bulk density of 1.71 kg/m3.
- M- Sand also known as Manufactured Sand is a prime alternative to Natural Sand which has the bulk density of 1.75kg/m3.
Density of Aggregate
Inert granular materials of non metallic substances such as sand, gravel, or crushed stone clusters in to Aggregates. Concrete obtained in the particles form and processed with water and Portland cement. It has two types, there are fine aggregate and coarse aggregate.
