Abstract
This study analyzes the effect of using variations of Grolen Hp19R and Sika Plastocrete RT-6 Plus additives in normal concrete of F'c 25 MPa. The resulting effect of mixing these two substances is where the Grolen Hp19R substance has high workability and to maintain the workability, Sika Plastocrete RT�6 Plus is used which can slow down the hardening process of concrete. The method used in this test is to make concrete mixture using SNI 03-2843-2000 for concrete quality 25 MPa. The study used cylindrical specimens measuring 10 x 20 cm with a percentage of soaking time at the age of 28 days. The results showed that the slump flow value generated from the percentage of Sika Plastocrete RT-6 Plus 0.3% substance added to Grolen Hp19R ranging from 0.2% to 1% ranged from 385 to 610 mm. It can be concluded that as the percentage of Grolen Hp19R additive use increases in concrete using Sika Plastocrete RT-6 Plus, the greater the slump value obtained. The results of the concrete content weight test show that the increasing percentage of the use of Grolen Hp19R additives in concrete using Sika Plastocrete RT-6 Plus, the smaller the value of the resulting content weight. The average compressive strength of normal concrete was 25.29 MPa, BN+SP 0.3%+GR 0.2% was 26.05 MPa, BN+SP 0.3%+GR 0.4% was 28.08 MPa, BN+SP 0.3%+GR 0.6% was 24.94 MPa, BN+SP 0.3%+GR 0.8% was 20.19 MPa, and BN+SP 0.3%+GR 1% was 17.93 MPa. The highest compressive strength value was found in the combination of Sika Plastocrete RT6 Plus 0.3%+Grolen Hp19R 0.4% which amounted to 28.08 MPa.
