Abstract

This study aims to determine the use of corn cob ash as an additive to cement in the production of CLC lightweight bricks according to SNI 03-2156-1991 concerning air flow light brick blocks by autoclaving process. The method used is an experiment in accordance with SNI 03-2156-1991 regarding light brick blocks of air flow with autoclaving process. The test object measures 59 × 19 ×10 cm and uses 45 specimens. The results obtained for dimensional testing exceed the required limits of SNI 03-2156-1991. The compressive strength of lightweight bricks is obtained at variations of 0%, 4%, 6%, 8%, and 10% respectively 3.07 N/mm², 3.68 N/mm², 4.54 N/mm², 4.29 N/mm², and 4 N/mm² with the optimum compressive strength value obtained at 6% variation and non-passing variation at 0% variation with a minimum requirement of 3.6 N/mm². The flexural strength of lightweight bricks is obtained at variations of 0%, 4%, 6%, 8%, and 10% respectively 0.27 N/mm², 0.63 N/mm², 0.81 N/mm², 0.65 N/mm², and 0.76 N/mm with optimum flexural strength values obtained at 6% variation and non-qualifying variations at 0% and 4% variations with a minimum requirement of 0.65 N/mm².
