Abstract
Excessive use of natural river sand causes degradation of river environment scenery and water quality as well as certain flora and fauna in the area. At the same time, continues generation of by-product from palm oil industry and coal power plants namely oil palm shell and coal bottom ash calls for the utilization of these waste in material production rather than disposing it as waste. The present research investigates the mechanical properties and acid resistance of oil palm shell lightweight aggregate concrete containing coal bottom ash as partial sand replacement. Four types of concrete mixes were casted by using coal bottom ash as partial sand replacement from 0%, 10%, 20%, and 30% by weight of sand. All specimens were air cured until the testing age. The compressive strength and splitting tensile strength of concrete were tested at 7, 28 and 60 days. The resistance of specimen against acid attack was evaluated by measuring the mass loss and compressive strength after concrete cubes exposed to sulphuric acid solution. The results show that OPS lightweight aggregate concrete exhibit higher compressive and splitting tensile strength also enhanced acid resistance upon inclusion of 10% of coal bottom ash as sand replacement.
