EFFECT OF DIFFERENT PERCENTAGE OF PLASTICIZERS ON PROPERTIES OF CONCRETE

Abstract

To improve the workability, strength, ability to control during work times and durability of cement concrete,
‘engineers, chemists, manufacturers and others have helped the concrete by adding some additional substances known as
admixtures. There are different kinds of admixtures are available; and each admixture has its own specialty. This paper has
been made an attempt to study the effect of plasticizer doses of 0.25, 0.30 and 0.35 percentage (by weight of cement) on
performance of M15 concrete grade. The tests considered for study are slump test and compressive strength test. The results
show that for the constant water cement ratio, increase of plasticizer dose in Concrete leads to gain of good workability.
Moreover, there is also slightly increase in compressive strength than that of normal concrete mix.
