What is CLC block?

Cellular Light Weight Concrete Bricks/ Blocks (CLC) is also called as Foam Concrete Blocks. Advantages: Light in Weight : CLC blocks are very lightweight with density ranging from 300 to 1800 Kg/m3. Three times less weight then clay or fly ash brocks. Eco friendly : CLC blocks are Environment-friendly.

What is the minimum reinforcement in slab?

Minimum reinforcement is 0.12% for HYSD bars and 0.15% for mild steel bars. The diameter of bar generally used in slabs are: 6 mm, 8 mm, 10 mm, 12mm and 16mm. The maximum diameter of bar used in slab should not exceed 1/8 of the total thickness of slab.

What is top and bottom reinforcement?

The bottom mat of reinforcement resists the positive bending moments at the critical sections in the span and is usually continuous over the entire slab area. The top mat resists the negative bending moments at the critical sections adjacent to the supports in the column strips and middle strips.

How do you calculate slab load?

Slab Load Calculation = 0.150 x 1 x 2400 = 360 kg which is equivalent to 3.53 kN. Now, If we consider the Floor Finishing load to be 1 kN per meter, superimposed live load to be 2 kN per meter, and Wind Load as per Is 875 Near about 2 kN per meter.
