Abstract
This paper aims to investigate the study of strength of fly ash based solid block using M-sand (MS) as replacement of fine aggregate. The cement is replaced by Fly ash (FA) at a constant proportion (10%). River sand (RS) is the commonly used fine aggregate in construction. Due to the high demand and less availability of RS, the cost of RS is increasing. So there is a need to find an alternative for RS. MS is an economical alternative for RS. Therefore, the fine aggregate is replaced by MS in proportions of 0%, 20%, 40%, 60%, 80% and 100%. The workability of concrete is determined by a slump cone test and compaction factor test. The mechanical properties of the concrete such as a compressive test for cube and solid block, split tensile strength, flexural strength and durability test. The concrete is placed in moulds, and they are cured and tested at 7, 28 and 90 days. The machine compressed concrete blocks are cured and tested. The results clearly state that the increasing amount of M-sand affects the strength of the block. From the results, it is found that the solid block mix designSF10MS60 has achieved the maximum compressive strength.
