An Experimental Investigation on Strength of Paver Block Using Dolomite as Partial Replacement of Cement and Addition of Polyester Fiber in Different Proportions

In this exploration through experimentation partially replacement of cement with dolomite powder and addition of polyester fiber in few percentages on concrete paver block. It is called fiber reinforced concrete paver block. Cement is a grinded material with adhesive and cohesive property that performs as a binder for distinct ingredients. Dolomite powder obtained by the sedimentary rock forming minerals dolostone and some similar features of cement. When dolomite powder used in concrete it lower the price of concrete paver block and enhance the strength of paver block by adding various percentages of polyester fiber. Polyester fiber is a man-made fiber produced from any long-chain synthetic polymer as the fiber producing ingredient. Water cement ratio 0.36 is used. In this experiment using Cement is partially replaced with dolomite powder in various percentages like 0%, 10%, 20% and 30% respectively and also adding polyester fiber in various percentages like 0%, 0.1%, 0.2%, and 0.3% respectively. Mix design M30 concrete grade is used. For concrete mix design paver block using IS 15658:2006 and IRC: SP: 63-2004. Size of coarse aggregate 10mm is used. To implement different test like compressive strength test at the end of 7days, 14days and 28days, split tensile strength test and flexural strength test at the end of 28 days.
