ABSTRACT

In this experimental evaluation utilization of dolomite powder by partially replacement of cement in different percentages on concrete paver block.One of the most essential components of concrete is cement. Cement is responsible for the majority of concrete's properties. Concrete is obtained through burning argillaceous and calcareous materials at a high temperature. As a result of the experience, a significant amount of carbon dioxide is emitted into the atmosphere. Not only will using dolomite powder minimise CO₂ emissions, but it will also reduce CO₂ usage. Dolomite powder manufactured by crushing the sedimentary rock-forming mineral dolomite, it is used as a cement substitute up to the desired amount in concrete. Cement and dolomite powder have some similar features. The use of dolomite powder in concrete can decrease the cost of the concrete paver block while also increasing its strength. By weight of cement, replacement percentages of dolomite powder like 0%, 10%, 20% and 30% were tested. The water cement ratio is 0.36.The concrete mix design M₃₀ is adopted. IS 15658:2006 and IRC: SP:63-2004 have been used to design a concrete paver block mix design. The coarse aggregate size is 10mm.After 7, 14, and 28 days, compressive strength was assessed, whereas flexural strength was recorded after 28 days.

Key words: Paver Block, Dolomite powder, Portland pozzolana cement, Water cement ratio, Compressive strength test, Flexural strength test.
