Research on alternative to replace natural sand in cement stabilized rammed earth blocks

Abstract

Natural Sand, which is being used extensively for all types of construction activities, is getting scarce now and many researchers have been put to task of testing other materials like manufactured sand for their usability in civil works. Present study aims at using the locally available soil for producing earth blocks. The materials like Auto aerated clay waste, manufactured sand are used in different proportions to see the possibility as a replacement for natural sand. Both the materials were used in proportion range of 35-65% along with 8% cement as a stabilizing agent. The cube compressive strength test was performed on soaked samples after 7 days and 28 days. It has been concluded from the result that the manufactured sand is cheap alternative material to replace natural sand.
