Abstract

Concrete for buildings, roads and bridges was very widely used in 2020. The development of concrete construction requires experts to improve the quality and workmanship of concrete in a modern, fast and strong way. Normal concrete without the treatment of any additives will make the quality and compressive strength of concrete around the standard standards. To answer this problem, the research objective is to add Betonmix additives to improve concrete performance and increase the compressive strength of concrete structurally. Normal compressive strength value of concrete at the age of 7 (seven) days is only 249.21 kg/cm2. The compressive strength of normal concrete at 28 (twenty eight) days is 260.75 kg/cm2. The composition of the addition of the right additive will increase the compressive strength of the concrete as planned obtained addititve Betonmix addition composition of 0.20% at the age of 28 (twenty eight) days concrete samples amounted to 300.26 kg/cm2.
