Abstract

Concrete is a commonly used construction material. The need for concrete mix materials is also increasing, one of which is sand. If sand continues to be takenit will have a negative impact on environmental conditions. For this reason, othersolutions are needed, one of which is by reducing the use of sand, resulting in a new innovation known as non-sand concrete. This research aims to determine thecompressive strength and porosity values of non-sand concrete with quartz filler. The composition of the mixture used in this research is a variety of combinedcoarse aggregate sizes of 5-10 mm, 5-20 mm and 10-20 mm, variations in thecement water factor of 0.4: 0.45: and 0.5 with the addition of 15% filler and A Cratio 2:1. The test objects used were cylindrical with a diameter of 15 cm and aheight of 30 cm. The number of test objects was 48, with details of 24 forcompressive strength and 24 for porosity. Testing the compressive strength of non-sand concrete uses a Compression Testing Machine based on ASTM C39 standards.
The results of the research show that variations in the combined coarseaggregate sizes of 5-10 mm, 5-20 mm, 10-20 mm, variations in the cement waterfactor of 0.4, 0.45 and 0.5, the highest compressive strength is obtained in thecombined coarse aggregate size of 5- 10 mm, variation of water cement factor 0.4,AC ratio 2:1 and filler content 15% amounting to 25.67 Mpa. For the porosity test results, variations in the size of the combined coarse aggregate were 5-10 mm, 5-20 mm, 10-20 mm, variations in the cement water factor were 0.4, 0.45 and 0.5. The smallest values were obtained for the combined coarse aggregate size of 5-10mm, variation of water cement factor 0.4, AC ratio 2:1 and filler content 15% witha value of 13.66%. The compressive strength of the non-sand concrete specimen without filler was 14.44 Mpa and the smallest porosity was 21.26%. The differencein compressive strength and porosity between non-sand concrete using filler andnon-sand concrete without filler is 11.23 Mpa and 7.5%. The results of the researchshow that the size of the combined coarse aggregate and the cement water factorwith the addition of 15% quartz filler greatly influence the compressive strengthand porosity of non-sand concrete.
