Abstract
Grolen HP19R is an additive that can significantly reduce water use on concrete pavements, making it easier to work. The test results show that this system can be used and gives a better value with a total compressive strength value of Mpa.The method in this study, the researcher made a concrete mixture using SNI 03-2843:2000 with Grolen HP19R as an additive to the concrete mixture by 0.4% and then the amount of water was reduced starting from 10%, 20%, 30%, and 40% of the amount of water in normal concrete. The concrete was treated for 3 days and 28 days and then tested to obtain slump values, compressive strength values and concrete fill weight.From the test results, it was obtained that the slump value on normal concrete was 7 cm. Meanwhile, the 5 variations added with the additive Grolen HP19R got the highest slump flow value of 58 cm in the normal concrete variation plus 0.4% Grolen HP19R. In addition, the concrete added by Grolen HP19R has a content weight between 2375.91 kg/m3 to 2351.22 kg/m3. For the results of concrete compressive strength obtained at the age of 3 and 28 days from the concrete added by Grolen HP19R with a reduction in the amount of water, the compressive strength increased along with the reduction of the amount of water and increased the slump value, and workability.
