Quantity Surveying:
In this quantity survey topic learning about manhole following component calculation starting calculation from excavation (Earth work), Bed Concrete, Manhole wall concrete, Manhole canopy concrete (cone volume), Riser concrete and benching Concrete. in all calculation using following formulas related to civil engineering formula as well as We can use these formulas as practically on the site. pipe laying 8" Dia PE pipe. ratio of concrete 1:2:4 mixing of fiber. using fiber 300 gm per cement bag. below picture show it. 👇👇👇👇👇👇
there are types of fiber?
Type of fiber using in Construction.
1) Carbon fiber concrete for high strength and chemical resistance
2) Steel fiber concrete for durability and crack-resistance
3) Blends of fiber concrete for a mixture of attributes
4) Glass fiber reinforced concrete (GFRC) for a light weight and strength
5) Plastic fiber concrete for flexibility and freeze-resistance
6) New anti Crack fiber.
