Abstract

Abstract. The problems of uncontrolled water use in the application of additive use as
an additive havebeen significant impact on the strength of concrete and the workability.
This paper describes an experimental study of the use of additives, Beton mix, as
additive to normal concrete with certain level. Specimens have been made without
reduced of water and also by reduced of water. This study focuses on the workability
and also the compressive strength of specimens. The results of the compressive strength
test at 28 days, showed that the specimens without reduce of water increased for
specimens with composition of Beton mix 0.15%, but the specimens that use less 0.15%
showed decreased the strength of the concrete linearly. In additional, the slump also
increased. In contrast to the specimens by reduced of water, a slump showed decreased
with a maximum reduction limit of 20%, and the strength of concrete showed an
increase of 5%.
