concrete mix design as per Nigerian standard code

2a-Concrete Mix Design

Normal Concrete Mix Design 1 Prescribed Mix (Standard Mix) , To design a concrete mix with characteristic strength of 30 MPa, what should the target mean strength be? Given that : defective level 5%, standard deviation 5 MPa , DwActual free water content (per m 3) = (M M Aw) ÷ volume of first trial mixCommon mistakes in concrete floor slab construction can be avoided with proper base preparation, mix design, placement, finishing, and curing If these steps are performed correctly, the owner can expect an attractive, durable product Standard concrete floor slab thickness in residential construction is 4 inch.
