Pengaruh Penambahan Superplasticizer Terhadap Perencanaan Beton Mutu Tinggi = 60 Mpa
Concrete is one of the construction materials commonly used for building construction. The use of concrete is increasing every day, so it requires that the concrete produced must have high quality. For concrete that has high quality must have a concrete compressive strengthof 40 - 80 MPa. To achieve the compressive strength of the concrete required the addition of materials such as Sikament-NN. The purpose of this experiment is to find the percentage of Sikament-NN used to achieve maximum concrete compressive strength. The method used is concrete with which is varied with 0%, 0,8%, 1,0%, 1,2%, 1,4%, and 1,6% of the weight of Sikament-NN from the weight of cement used. The ready-to-test concrete is measured by the compression testing machine and the slump value is obtained from the slump test method. The results obtained from testing the percentage of Sikament-NN needed in the concrete mixture with a value of FAS 0,33 give maximum concrete compressive strength of the concrete with the addition of Sikament-NN of 1,0% by producing an average compressive strength of 47,06 MPa with slump of 14 cm. The results obtained still meet the high quality concrete standards, The additive of Sikament-NN with certain levels can increase the value of compressive strength of concrete.
