This study is based on “Total replacement of cement with natural available raw material such as Lime and silica”, it also can be used as a Cement replacement in concrete. Concrete paving blocks are ideal materials on the footpaths and roads for easy laying better look and finish. In this paper, a parametric review for producing paving blocks using Lime and Silica is presented. Lime and Silica are added with the replacement of cement as a binder material in paver blocks. There are, as there have always been, two critical issues with this type of cement replacement. The change in physical properties with respect to compressive strength and the cost analysis of the alternatives. The first stage of this research looks at the change in physical properties of a standard concrete mix when lime is substituted for cement with respect to compressive strength. The results from this research show a linear decline in strength with a linear increase in the relative percentage of lime to cement. A traditional cost analysis looks only at the first or construction cost, without considering the long term cost to mitigate for the increased global warming emissions resulting from the manufacturing process of Portland cement. The Lime Pavers does not cause pollution and they are Ecofriendly. To achieve high strength levels, block producers generally define Lime mixtures by a trial and error process.
