Abstract:
ABSTRACT: The increasing price of light brick and clay brick quality, it is deemed necessary to make bricks
using materials that are cheaper and easier to obtain, namely by utilizing sludge of Water Treatment
Installation 2 PDAM Bandarmasih. For this reason, a study is needed to utilize the abundant sludge waste,
while also aiming to reduce the negative effects caused by the accumulation of sludge.
This study aims to determine the physical and mechanical characteristics of bricks made from sludge of Water
Treatment Installation 2 PDAM Bandarmasih.
Based on this research obtained that most of the visual physical characteristics did not meet the requirements of
SNI 15-2094-2000, because the bricks produced were uneven and cracked. There is no brick size that meets the
SNI 15-2094-2000 requirements because the bricks are experiencing considerable depreciation. The salt crystal
content meets NI-10, 1978 requirements, so it is in the no hazard category. For mechanical characteristics only
apparent density that meets SNI 15-2094-2000 requirements, while compressive strength and water absorption
do not meet the requirements.
