An Experimental Study on Partial Replacement of Fine Aggregates with M-sand

Abstract

Shortage of good natural sand due to depletion of resources and limitation due to environmental considerations has made concrete manufacturers to look for suitable alternative fine aggregate. One such alternative is “manufactured sand”. Manufactured Sand is a term used for aggregate materials less than 4.75 mm and which are processed from crushed rock or gravel . Due to booming of construction activities in our country, natural sand resources are increasing depleted and its costs is becoming increasing high. Workability strength and Durability of concrete with manufactured sand as replacement to natural sand in proportions of 0%,5%,10%,15%,20% and 25% is studied. This project was, therefore, conducted to study the influence that manufactured sand having compressive strength, split tensile strength of concrete for 7 days ,14 days ,28 days, and to access the prospects of using manufactured sand as a replacement of natural sand. The experiments were conducted on M30 concrete grade. Slump cone test is conducted to determine workability on fresh concrete. It can therefore, be concluded from the finding of the study that when the availability of natural sand is scarce are in cities where the price of natural sand is as expensive as manufactured one, manufactured sand concrete mix is a viable and better alternative to the use of natural sand.
