How much sand required for 1000 sq ft rcc roof slab? The amount of sand required for a 1000 square foot RCC (Reinforced Cement Concrete) roof slab depends on the thickness of the slab and the mix ratio of concrete being used. Typically, for a standard 4-inch (0.33 feet) thick slab, you would need about 0.018 cubic yards or approximately 0.49 cubic feet of sand per square foot. So for a 1000 square foot slab, you would need approximately 490 cubic feet of sand.
When we are planning of new house construction there is a lot of questions arises in our mind how much unit of sand required for 1000 sq ft house. Looking around your budgets and plan to estimate. Construction of your house estimate consist of all direct and indirect cost of building materials such as sand, fine aggregate or stone, sand, cement and steel.
Sand weight is calculated on the basis of density of river sand and M sand (manufactured sand), natural sand is obtained from river Basin and artificial or manufactured sand is is obtained by crushing of stone in Crusher mill into fine particles.
The sand which are collected from river basin known as river sand, it is find sand. And the sand which are collected by crushing of stones are known as M sand (manufactured sand). Sand is not only required for preparing RCC, mortar and plaster but also used for filling and flooring too.
Generally density of M sand is more than compared to River sand. 1 CFT sand weight in kg generally depend on many factors like wet, dry, loose & packed sand condition.
One unit of sand is equal as 100 cubic feet or 1 brass. One unit of sand = 1 brass which is equal to 100 cubic feet volume and it is also used as measuring of surface area of 100 square foot. 100 cft is equal to 1unit of sand hence 100cft = 1unit
The terms “unit” is used locally in tamilnadu for measuring majorly for sand, 20mm aggregate (mukka jally), 40mm aggregate(1.5″ jally). Usually lorry suppliers use this term often because they supply those above said materials. Lorries comes with 1 unit, 2 unit ,4 unit lorry, 7 unit, 8 unit capacity.
Generally roof slab thickness is kept about 4 inch thick at general a standard used for residential building and thickness of 5 to 6 inch for commercial use, in this article we calculate cement required for RCC roof slab at 4 inch, 5 inch and 6 inch thickness.
Roof slab casting is process of laying and putting concrete mix in horizontal direction and structure over brickwork. Cast of roof slab reinforcement main bar and cross bar in distributed over shuttering areas of roof slab and then we put concrete mix of M20 or m25 grade of concrete that is known as roof slab casting.
