Abstract :
This research aims to determine the effect of time delay variations due to the use of Grolen Hp19R and Sika Plastocrete RT-6 Plus on f'c 40 MPa quality concrete. Concrete with an f'c quality of 40 MPa is usually used for construction projects that require quite high compressive strength, such as multi-storey building structures, bridges, roads and other infrastructure.The method used in this test is to make a concrete mixture using SNI 03-2843-2000 with Grolen Hp19R 0.4% and Sika Plastocrete RT-6 Plus 0.3% as additional ingredients.Therefore, based on the compressive strength test, the compressive strength value for concrete aged 28 days was obtained, for normal concrete the highest compressive strength value was obtained at 32.99 MPa at a time delay variation of 0 minutes, BN+SP 0.3% obtained the highest compressive strength value at 42.04 MPa at a time delay variation of 0 minutes, BN+SP 0.3%+GR 0.4% obtained the highest strength value of 40.48 MPa at a time delay variation of 60 minutes, and BN+GR 0.4% obtained a value The highest compressive strength was 32.20 MPa at a time delay variation of 60 minutes.
