The utilization of concrete masonry units for skyscraper stack bearing development has made a requirement for concrete block with high compressive strength. To accomplish high strength levels, block makers for the most part characterize concrete mixtures by an experimentation process. The most widely recognized system is to create some trial mixtures having diverse cement content utilizing the hardware accessible in the block plant and test the strength of blocks. This approach is exorbitant, tedious and by and large prompts costly answers for utilizing a lot of cement. Also, it makes hard to test new mixes of aggregates and admixtures once aggravates particularly the plant schedule. In this paper is displayed a mix design strategy for auxiliary concrete blocks in light of research center tests. At first a reference mixture is considered. In this stage it is conceivable to differ the sort and extent of aggregates, admixtures and water content to accomplish a reasonable face surface with lower energy of compaction. From that point onward, a few mixtures are created changing the cement content and density. Tube shaped examples was delivered with these mixtures and tried in compressive strength. With the outcomes, it is expounded a mix design outline where the coveted compressive strength can be acquired by differing the total/fastener ratio and density. The last stage is trying some chosen mixtures in real block machine, deciding both density and compressive strength. With the outcomes it is conceivable to make the last changes in the mix proportions. The utilization of this technique in a block plant of the south of Brazil prompted agreeable outcomes demonstrating that is conceivable to estimate of the mechanical opposition of the concrete blocks beginning from research center examinations in round and hollow examples and likewise exhibited the significance of the control of a few parameters identified with the productive process for the compressive strength of the units.
