Abstract

Concrete is an important material in the world of construction. Because of the importance of concrete materials in construction, there has been a lot of development or change in knowledge about concrete. In the formation of non-
sand concrete, many voids are produced. One way to fill these voids is filler so that the porosity is reduced. In the formation of non-sand concrete with additional ceramic filler, the size of coarse aggregate and filler content are varied with the aim of determining the effect of coarse aggregate size and ceramic filler content on the strength and porosity of non-sand concrete with ceramic filler. The composition of the mixture used in this research is a combined coarse aggregate size of 5-10 mm, 5-20 mm, and 10-20 mm, filler content used is 10%, 15%, and 20%, water cement factor (FAS) 0 .5 and a cement aggregate ratio of 2:1. The test object used in this research was a cylinder measuring 15 cm x 30 cm using a compression testing machine based on the ASTM C39 standard. The results of the research showed that non-sand concrete specimens with variations in the combined coarse aggregate size of 5-10 mm, had the highest average compressive strength of 22.08 Mpa at 15% ceramic filler content, and
19.06 Mpa at 10% filler content. , and at a filler content of 20% it is 17.74 Mpa. Variations in the combined coarse aggregate size of 5-20 mm, have the highest average compressive strength of 20.57 at 15% filler content, 17.17 Mpa at 10% filler content, and 15.66 Mpa at 20% filler content. . Variations in the combined coarse aggregate size of 10-20 mm, have the highest average compressive strength of 16.80 at 15% ceramic filler content, 15.85 Mpa at 10% filler content, and 14.91 at 20% filler content. Mpa. The porosity value obtained from variations in combined coarse aggregate sizes of 5-10 mm is 16.25% at a filler content of 10%, at a filler content of 15% it is 14.72%, at a filler content of 20% it is 17.39%, variations in size The combined coarse aggregate of 5-20 mm is 17.08% at a filler content of 10%, at a filler content of 15% it is 16.92%, at a filler content of 20% is 18.23%, and the variation in size of the combined coarse aggregate is 10-20 mm, namely 18.53% at a filler content of 10%, at a filler content of 15%,
namely 16.81%, and at a filler content of 20%, namely 19.83%. The greater the compressive strength value, the smaller the porosity value, if the compressive strength value is smaller, the greater the porosity value.
