Abstract

Concrete is one of the building materials are very useful in the construction, where concrete is a mixture of
Portland cement (PC) or other hydraulic cement composition includes a mixture determined between fine
aggregate, coarse aggregate and water, with or without the use of additional materials. The study was conducted
to determine the compressive strength of concrete and other specifications that concrete is achieved by the
addition of Conplast SP 337. That is done using a cube-shaped test specimens measuring 15 cm x 15 cm x 15 cm
with 5 (five) variation of mixture B1, B2, B3, B4, and B5, each four (4) specimens. for each test age of 3 days, the
age of 7 days, 14 days, 21 days and 28 days. From the research, it was found that the compressive strength of
concrete with each stir the mixture obtained 1.2: 2: 3 (B5) compressive strength greater of 4.5% of the
compressive strength of normal concrete specimen (B1). And the compressive strength of the mortar 1: 2,5: 3 with
the addition of SP 337 (B5) is lower than the compressive strength of normal concrete specimen (B1) amounted to
23.71%.
