Abstract

Concrete is one of the most commonly used constructoin materials in infrastructure developmen.t concrete has high compressive strenght, is resistant to loads, and has good resistance to weather and the environment. One thing that influences the quantity of concrete is water concrete mixture. This research aims to analyze the effectof water content on the compressive strength of 25 MPa quanlity concrete using the master rheobuild 6 additive. The research method used is laboratory experimental. The test object is a concrete cylinder with a diameter of 10 x 20 cm. The variations in water content used were a reduction of 5%, 10%, 15% and an addition 5%, 10%, 15% with a Master Rheobuild 6 additive dosage of 1,5 of the cement weight. Compressive strength tests were carried out at 7 days, 14 days and 28 days of concrate. The reseearch results show that the higher the water content, the lower the compressive strength of the concrete produced. At 10% water reduction, the compressive strenght of concrete reaches 33,22 MPa. Meanwhile, at 5% and 15% water reduction, the compressive strenght of concrete is 17,11 MPa and 30,31 MPa respectively. Meanwhile with the addition of 5% water, the compressive strength of the concrete reached 24,16 MPa, while with the addition of 10% and 15%, the compressive strenght of the concrete was around 31,82 MPa and 15,38 MPa respectively. The use of the additive Master Rheobuild 6is able to maintain the slump of the concrete without increasing the water content excessively.
