An investigation of laterite as fine aggregate to develop eco-friendly mortar

Major objective of the study was to examine the suitability of laterite as fine aggregate in mortar. Conventional Cement mortar was prepared using river sand for different cement mortar ratios from 1:3, 1:2 and 1:6. Replacing the natural sand by laterite and manufactured sand by laterite for the rep...

Description
Summary:Major objective of the study was to examine the suitability of laterite as fine aggregate in mortar. Conventional Cement mortar was prepared using river sand for different cement mortar ratios from 1:3, 1:2 and 1:6. Replacing the natural sand by laterite and manufactured sand by laterite for the replacement level of 20, 40 and 60 % were cured at room temperature and tested in accordance with IS:2250-1981. Water absorption and durability tests (sulphate attack, chloride attack and acid attack) are conducted after the initial curing of mortar cubes. Compressive strength of masonry was examined by testing masonry prisms. The test result shows that up to 40 % of replacement of laterite in river sand and manufactured sand is suitable for masonry work. The rebound losses, has a moderate impact on the workmanship of the masonry work.
