Abstract

This study focuses on observing how much damage to concrete in the mixing and maintenance process using brackish water with variations in the type of cement brand and its effect on the compressive strength of concrete K-175 (Normal Concrete) with curing 28 days and knowing the relationship between the modulus of elasticity and strain on the compressive strength of concrete. The results showed that the highest compressive strength of concrete at the design age of 28 days was 253.790 Kg/cm² or 20,447 MPa using brackish water and a mixture of Gresik cement materials followed by Tiga Roda cement of 20.313 MPa, Conc cement of 19,506 MPa and Holcim cement of 17,236 MPa. So that the relationship between compressive strength and modulus of elasticity and strain due to cement variations shows a value of R = 0.9999 or reaches a value of 1 so that it has a very significant effect.

Abstract

In general, the water used for making concrete is water with a pH of 7, as well as the standard testing in the Lab, but in reality sometimes the work of making concrete in the field does not pay attention to the pH of the water used, such as the use of swamp water or well water made around the project site. The use of concrete structures that are in direct contact with sulfuric acid compounds will affect the quality of the compressive strength of concrete because sulfuric acid can corrode concrete. This study observes how much damage to the concrete if in the mixing and maintenance process using acid water with a pH level <7 and the effect on the compressive strength of concrete with curing duration of 3, 7, 14, and 28 days. The highest compressive strength of concrete at a design age of 28 days is 240,196 Kg/cm² or 19,237 MPa using acid water in a concrete mixture using Conch brand cement, followed by Gresik cement at 18,167 MPa, Tiga Roda cement at 16,837 MPa and Holcim cement at 16,837 MPa.
