Abstract

This study aims to determine the effect of using type E admixture by reducing the amount of water content on the slump value and compressive strength of concrete in quarry Ex. noisy. The mixture used in this study was a normal concrete mix, a mixture with the addition of Type E admixture 1%, 1.5% and 2% taken from the weight of cement, by making cylindrical test objects measuring 15 cm x 30 cm with a total sample of 12 pieces and concrete compressive strength test plan at the age of 7, 14 and 28 days. The results of this study for normal concrete mixtures obtained a slump value of 60 mm, whereas for mixtures using type E admixture, the slump value was between 62 – 67 mm. From this study, the ideal mix was produced for a mixture using 1.5% E type admixture with a compressive strength of 22.64 MPa, while for normal concrete mixtures with a compressive strength of 20.38 MPa, for a mixture using E type 1 admixture % obtained a compressive strength of 21.23 Mpa, and the mixture with the addition of 2% type E admixture obtained a compressive strength of 21.79 Mpa. However, the mixture with the addition of 2% E type admixture experienced a decrease in compressive strength compared to the previous mixture, namely with the addition of 1.5% admixture.

Abstract

This study aims to analyze the aggregate properties for concrete mixtures on the compressive strength of concrete and compare the aggregate material between quarry Ex. Cikeruh (which is used in the project), quarry Ex. Cideres, and quarry Ex. Cilutung. Tests carried out in accordance with SNI and Bina Marga specifications. The results of testing in the laboratory were obtained. From the three quarry, all of them were suitable for use as mixed concrete materials because they met the specifications required by SNI and Bina Marga. Judging from the results of the concrete compressive strength test, the quality plan fc'20 28 days old, Mixed Quarry Ex. Cideres has a higher compressive strength value so it gets a quality yield of 24.34 MPa while Quarry Ex. Cikeruh obtained 22.08 Mpa, and Quarry Ex. Cilutung gets 20.38 Mpa.
