Abstract
This paper presents a study conducted to
determine the suitability of partial replacement of
sand with laterite soil and manufactured sand in
M20 grade concrete. The first phase is to find the
maximum percentage of sand can replace with
lateritic soil and manufactured sand for both M20
grade concrete. Concrete mixes containing
0,10,20,30, 40% sand replacement levels were cast,
with super plasticizer. Split tensile strength,
compressive strength test and flexural strength were
conducted in accordance to the existing standard.
Results show maximum of 20% replacement levels
of sand by laterite attained workable concrete with
satisfactory strength beyond that lateritic concrete
is not workable And 40% replacement of sand by
manufactured sand shows maximum strength. Mix
proportion is taken as 1:1.5:3 based on the design
result.
