ANALYSIS OF EFFECT WATER REDUCTION AND ABRASION VALUE OF COARSE AGGREGATE PADA BETON BY USING SUPERPLASTICIZER VISCOCRETE 1050 HE
Abstract
With the rapidity of the construction world , the use of materials will also increase, one of which is the increasing use of concrete. One of the developments is to add additives to the concrete dough to be able to achieve the expected results. This study uses Superplasticcizer Viscocrete 1050 HE which is the latest type of output from PT. SIKA has the advantage of being able to reduce water by more than 30%. The discrete content used is 1% of the weight of cement and the water reduction content is 0% to 40%. The results of the concrete compressive strength test were obtained results with the use of Viscocrete 1050 HE 1% with a reduction of water of 35% having a maximum concrete compressive strength value of 40.2 Mpa at the age of 28 days for coarse aggregates that have a low abrasion value (AK1) and of 39.8 Mpa at the age of 28 days for aggregates rough that has a high abrasion value (AK2).
