Abstract
The costs of building materials constitute about 60%-65% of the total cost. It is desirable to economize the cost of material to be used in the structure. An analytical study has been attempted to compare the economical viability of using rubbercrete blocks for the benefit of mankind by reducing environmental pollution also. In This study, rubbercrete blocks cast with 5% of tyre chips replacing fine aggregates and 20% coal ash replacing cement. It is found the rubberized concrete blocks of M10 grade produced were having satisfactory strength. Cost wise also they were found to be economical as there is a reduction of the cost by8% to 10%.
