What is dead load ?
The dead load is a self weight of the beam column and doesn't change position during life of the construction or structure.
What is live load ?
The live load is a weight of the person, furniture and others stuffs which carries some weight on slab and there loads are variable during the life of the structure.
Density of materials?
Cement density = 1440 kg/meter cube
Sand density = 1650 kg/meter cube
Aggregate = 1200 to 1750 kg/meter cube
PPC = 2400 kg/meter cube
RCC = 2300 kg/meter cube
Bricks = 1600 to 1920 kg/meter cube
Concrete block = 2100 kg/meter cube
Mortar = 2080 kg / meter cube
Concrete = 2300 kg/ meter cube
What is the curing time period of construction.
Opc = 10 days minimum
ppc = 7 days minimum
Super sulphate cement = 7 days minimum
Mineral and admixture added cement
= 14 days minimum
De-shuttering time of formwork
Column = 16 to 24 hours
Rcc slab = 10 to 21 days
Rcc footing = 3 days
Rcc beam bottom = 15 to 28 days
What is scaffolding?
Ans. Temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridge and all other man made structures.
