Analysis of Workability on Construction of Interlocking Concrete Pavement Blocks (ICBPs) Using Superplasticizer As Admixture

In this experimental study water proofing superplasticizer is used in M 35 mix design with adding it maximum 2 % of superplasticizer by weight of cement in the construction of concrete block pavements. Superplasticizer is added 0.5 %, 1.0 %, 1.5 % and 2.0 % by weight of the cement in construction of the concrete pavement blocks. The effect is shown in the workability of the M 35 mix design considering w/c ratio on 0.35, 0.40, 0.45, 0.50, and 0.55 and slump value considered. The use of superplasticizer helped also in reduction of water percentage in concrete mix with comparison to conventional mix design without using superplasticizer.
