Variation Analysis Addition of Admixture Consol N10 MB to Concrete Compressive Strength

One of the efforts to improve the quality and quantity of concrete produced is by providing added material to the concrete mixture. PT. Kimia Konstruksi Indonesia produces cosol which is chemical construction of high quality, durable, easy to apply and more economical price. Consol has various types of products with different advantages such as Consol N10 MB is an admixture for high strength concrete. The purpose of this study is to determine the value of concrete compressive strength with the addition of material variations admixture to the N10 MB consol. Concrete design refers to the DoE and SNI 03-2493-1991 methods with cylindrical molds measuring 150 mm x 300 mm. Concrete quality of the K-300 plan with the percentage addition of Consol N10 MB, 0%, 0.1%, 0.3%, 0.5%, 0.8%, 1%, 1.2% and 1.5% with time testing at the age of 28 days. The test results show that the tendency of the average compressive strength graph has increased with the addition of N10 MB to 0.5%, with the highest average compressive strength obtained at the addition of 0.5% N10 MB consol of 369.48 kg/cm2 and the resulting equation is y = -113.5 x2 + 109.8 x + 327.1
