Abstract

Lightweight Concrete is a concrete that weighs below the normal concrete. One way of making lightweight concrete is to replace rough aggregates or gravel using lightweight aggregates. Some examples of mild aggregates include roasted clay, pumice, or artificial aggregates so that the resulting concrete will be lighter than regular concrete. Concrete with an artificial aggregate of newspaper waste, which will be called aggregate concrete this paper is one type of lightweight concrete. This study aims to examine the benefits that can be derived from the use of paper aggregate concrete. In this study, the aggregate used as a concrete aggregate of paper derived from paper waste formed to resemble granules of 10-20 mm granulated size, cement volume ratio: aggregate = 1: 2, with the value of cement water factor of 0.3-0 , 4 as the initial reference in mix design. Paper aggregate variations used were 0%, 25%, and 40%.The variation is based on the percentage of paper aggregate volume of the aggregate overall. The paper aggregate concrete test specimens were made with blocks of length 60cm, width 10cm, and height 20cm, and each variation was made as many as 10 pieces of test specimens consisting of a compressive strength test. Testing of physical properties and mechanical concrete is implemented when the test object is 14 days old. The results showed that the weight value of the unit of paper aggregate concrete with cement mixture: aggregate = 1: 2 and the paper aggregate content of 0%, 25%, and 40% of the overall aggregate were 1,3117,5kg / m3, 1,2013,7 kg / m3, and 1.0926,8kg / m3 with compressive strength value of 6.536341783Mpa, 4.702098166Mpa, 5.478232476Mpa, respectively. This suggests that the paper's aggregate concrete, included in lightweight concrete types that can be used in lightweight structural construction.
