Description. The compressive strength ranges from 1800-2800 psi (13 to 20 Mpa). Density will be approximately 600 to 1000kg/m3 depending on board type. It is the cgs unit of density; to do this, we must first convert the SI unit into the cgs unit, which is 1km/m 3 = 1000grams/(100 100 100 cm 3) = 1/1000 g/cm 3.. 3) 150 is density of cement concrete in lb/ft3. Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. Cement act as binder in a concrete, knowing its density will be very useful to change the concrete characteristics. In Bags = 8.64 bags. Used for determining the expansion of cement. Scratch & Brown Base Coat Stucco (No. Search: Cement, mortar weighs 2.162 gram per cubic centimeter or 2 162 kilogram per cubic meter, i.e. These values for density of some common building materials were collected from sites across the Internet and are generally in agreement with multiple sites. The bulk density of fresh mortar was determined following BS EN 1015-6 (1999). Types Of Plasters Common ratio are: 1 cement: 1 lime: 6 sand for external plasters, below damp proof course 1 cement: 2 lime: 9 sand for external plasters on walls Guniting Plaster: 1 cement: 3 sand which is applied under great pressure - 2.5 kg/cm2 with the use of special gun.
