Studi Kekuatan Pasangan Batu Bata Pasca Pembakaran Menggunakan Bahan Additive Zeolit

Abstract

In this research the reseacher used the worst material of soil with additive materials named the
ash of bagasse in purpose to utilize the waste and to increase the strength of the bricks so that it
can produce cheap bricks with good quality that can be an alternative for bricks industries.
Soil samples were tested in this study is derived from the silt soil region Nyunyai road,
Kec.Rajabasa. Variations in the levels of the mixture used is 6%, 8%, 10%, and 12% and drying
for 7 days, with burning treatment and without burning treatment. Based on the results of physical
examination native land, USCS classify soil samples as fine-grained soil and belong to the CL
group.
The results showed that the brick-making post-combustion using zeolite mixture meets the
Indonesian National Standard (SNI) bricks for building materials. In general, the addition of
zeolite material in the soil reduces the value of the density of the soil mixture. For the compressive
strength of bricks without combustion and combustion processes are best shown in the addition of
a mixture of 10%-12%.
