(PDF) THE EFFECT OF QUARRY DUST WITH CEMENT . Usage of quarry dust also reduces the cost of concrete (economical) because it is a waste from the .
· Therefore, this research was to observe the possibility of quarry dust to be included in a concrete mix. The quarry dust has been used as a partial replacement for cement proportion at different levels of replacement (25%, 30% and 35%). Quarry dust was used as the main material in this project to measure the effectiveness of concrete performance.
concrete using industrial waste such fly ash, quarry dust, polymer and silica. One of the methods is to mix the quarry dust with the concrete. In this research, a quarry dust waste was added in the different proportion by weight of cement. The effect of quarry dust as a sand replacement in concrete were investigated 36 numbers with
