Abstract :

<p>&lt;p&gt;&amp;nbsp;For many years, sand has been predominantly used as fine aggregate in civil engineering construction. More recently, the source of quality sand has been fast diminishing resulting in ever increasing cost of construction. Laterite is now seen as a possible replacement for sand in concrete mix. In this paper we tried to study the behavior of concrete under compression when fine aggregate that is locally available river bedded sand is partially replaced with laterite sand by 0%, 7.5%, 15%, 22.5%, and 30% to the weight of fine aggregate for design mix of M30 concrete with 0.45 as water cement ratio and the coarse aggregate used is locally available basalt stone. The laterite used is taken from basavakalyan, Bidar District of Karnataka state. The numbers of specimens prepared are 60 and size of specimens is 150mm x 150mm x 150mm. The cube compressive strength is determined at 3, 7, 21, 28 days of curing. These results are compared with the results of normal concrete, and suitability of it is studied.&lt;/p&gt;</p>
