Abstract :
Concrete is a composite building material, consisting of cement, aggregate, and
water, sometimes also added mixture to produce strong and good quality concrete. Concrete
that has good quality and high compressive strength reduces the risk of structural failure,
the concrete mixture used is usually a chemical substance that is able to maximize the
usefulness of the concrete itself, thereby increasing the compressive strength of concrete
and the durability of concrete. One of them is Master Glenium which is a Polycarboxylate
Superplasticizer Ether developed for high early strength, the use of this innovative material
is expected to improve the quality of concrete compressive strength. The purpose of this
study is to determine the effect of Master Glenium on the compressive strength of concrete,
so that it can be used as a reference in planning the manufacture of quality concrete. This
test uses aggregate requirement test method, slump test and compressive strength and
performs a combination of mixing Master Glenium additives. The results of testing the
compressive strength of concrete with a lifespan of 14 days showed the average result of
concrete compressive strength of 23.33 Mpa and the average percentage of concrete
compressive strength of 107.5%. From the results obtained from the test, it can be
concluded that concrete has a compressive strength value and percentage of more than the
standard target life of 14 days concrete of 19,074 Mpa.Master Glenium Type 8595
Increases the compressive strength of concrete at the age of 14 days. The following shows
the results that the compressive strength of concrete can increase during the treatment
period reaching 14 days with an average compressive strength value of 23.33 MPa.
