Abstract

This research aims to process additives as additional ingredients for concrete mixtures, which aims to maintain the quality of concrete. In this research, the researchers tried to change the composition of the concrete by adding the Grolen HP19R additive to the compressive strength test of FC 25 Mpa concrete to obtain further results in accordance with the compressive strength determined as a reference material. The concrete mixing method uses Grolen HP19R additives using a job mix design fc 25 Mpa which is added to the concrete mixture with variations of 0.4%, 0.6%, 0.8% and 1% of the weight of the cement used. The concrete is cured for 3 days and 28 days then tested to obtain the slump value, compressive strength value and unit weight of the concrete. From the tests carried out, it was found that the maximum slump value was found in the concrete added with 0.8% BN+Grolen HP 19R compared to normal concrete with a value of 612.50%. Grolen HP19R can increase the density of concrete with a maximum weight at 28 days, namely the BN+GR 1% variation with a value of 2809. Grolen HP 19R also increases the compressive strength value of concrete aged 28 days with a maximum value found at BN+GR 1% with a result of 414.66 %.
