Kediri Regency is a government area in East Java Province, which is currently developing infrastructure development. In general, infrastructure development in Kediri Regency often utilises the function of concrete in its reinforcement. The Brantas River is a source of fine aggregate mining products used as concrete constituents, where the quality of the Brantas River sand is quite good. The coarse aggregate often used in Kediri Regency comes from the Kedak area. Unlike the fine aggregate, the quality of the coarse aggregate originating from the Kedak area has different wear values. The tests carried out were to carry out aggregate, slump, and compressive strength tests when the curing age of concrete had reached 28 days. The method used in this study was experimentally by making concrete according to the SNI 03-2834-2000 method with sampling conditions of coarse aggregate wear under the criteria and using a combination of additives master sure 1007 and master glenium ace 8595. This type of additive is a superplasticiser of concrete paste and is believed to improve the quality of the compressive strength of concrete. The concrete compressive strength target can be achieved using a combination of 0.35% master sure additives and 0.25% master glenium from the percentage of a binder. The results of the average compressive strength of the three specimens obtained were 15.52 MPa from the design target of 15 MPa. The use of additives master sure, and master glenium in manufacturing concrete with a wear value of coarse aggregate exceeding the standard effectively maintains the compressive strength of concrete according to the planned target so that the coarse aggregate condition that does not pass the aggregate wear test can still be used as a concrete constituent material, of course, by using a combination of master sure and master glenium additives.
