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.
