Abstract :
This research aims to determine the behavior of using Polyneva HE in concrete mixtures. Polyneva HE is an additive that has a dual function to reduce the amount of water used in concrete mixtures with a certain consistency, so that the mixture will be easy to work with or the mixture will become plastic (easily formed). The results of this test show that the use of Polyneva HE as an additional ingredient in the concrete mixture has good compressive strength. The concrete mixing method uses Polyneva HE additives using job mix design K-300 which is given additives to the concrete mixture with variations of 0.4%, 0.8%, 1.5% of the weight of the cement used. The concrete is cured for 3 days, 7 days and 28 days and then tested to obtain the slump value, compressive strength value and unit weight of the concrete. From the tests that have been carried out, it is known that for the slump value obtained, the more Polyneva HE added, the higher the slump value or workability value, the maximum slump value for concrete that added 1.5% Polyneva HE to normal concrete was 545.78%. Polyneva HE increases the density of concrete with the maximum weight found at 28 days, namely normal concrete + Polyneva HE 0.8% with a yield of 3.114%. Polyneva HE also increases the compressive strength value at 28 days with a maximum value for normal concrete + Polyneva HE 0.8% of 13.333%. Polyneva HE also increases the density of concrete with the maximum weight found at 28 days, namely normal concrete + Polyneva HE 0.8% with a yield of 3.114%.
