Abstract

East Nusa Tenggara province is a region abundant with pumice content. Pumice is a frothy lava composed of compacted glass pyroclastic with very mikrovesikular wall extrusive igneous volcanoes bubbling, very thin and translucent and that is a common product of volcanic eruption and the general shape of the zones of the upper silicate lava They uses of pumice, among others: metal , raw material, lightweight brick, paint, plaster material, ceramics, sand paper raw materials and much more, pumice stone contain silica so that it can be used as a subtitude filler in asphalt mixture. This research was conducted to determine the effect of using pumice stone ash as a substitute filler in asphalt mixture. It will be seen from the value of stability and flow by using Marshall. There are several steps in Marshall’s method need to be done include: testing gravity, aggregate gradation planning, aggregate composition plane, aggregate bulk density calculation, the maximum mixture specific test and the calculations of the parameter values in Marshall’s method. The results of these research are finding higher levels of filler in asphalt mixture, the higher value of the stability while the value of flow decreases with increasing value of filler content in the asphalt mixture. Based on test results, the value of the variation of filler that meets spesifications Marshall’s is 1% and 2%, as only two variations of these filler levels that meet all of parameter value Marshall.

Abstract

The district is an area with the greatest potential pumice in East Nusa Tenggara. Pumice limited usage and the potential availability of the shows that pumice has not been used optimally. Seeing its potential, then another attempt to capitalize on this pumice is used as an alternative to coarse aggregate in normal concrete mix. This will affect the quality of the concrete, so this study aims to determine the compressive strength and split tensile strength of concrete when coarse aggregate in concrete partially substituted by using a pumice stone. Specimens used were as many as 60 concrete cylindrical specimens with 30 MPa compressive strength plan. Pumice stone is used on concrete with substitution of the broken stone. Substitution percentage was 15%, 25%, and 50%. Concrete testing is given 3 different treatment that uses natural pumice stone, pumice stone after the coating as well as the addition of chemicals given in the form of sikafume and sikament Ln. Based on test results, the concrete with substitution levels of 15%, 25%, and 50% lower compressive strength, whereas when given some treatment increases the compressive strength.
