|a Cement paste is known as type of binder that can be used in concrete structure and pavement development to provide stronger bonding between the paste and aggregates. Quarry dust is a byproduct from quarries activity that is widely used in construction field as an alternative material to replace cement and sand content. The purpose of this study is to evaluate the effect of percentage of cement replacement and particle size of quarry dust towards the mechanical properties on ordinary cement paste design in order to propose an optimize combination between the two parameters. Three different batches of mix design were produced where cement were replaced at 10%, 20% and 30% using quarry dust of 75..m, 300..m and 600..m apart from the control mixture. The mechanical properties like density, water absorption and compressive strength were determined. In this research, the highest average density obtained is 1.748g/cm3 for batch QD20 in 600.... and QD30 in 300.... with same 12.46% of water absorption. The range of water absorption in this project is 11.19% to 14.24%. Furthermore, the samples for batch QD10 in 300..m received the highest compressive strength at 7th and 28th day which is 24.51MPa and 39.32MPa respectively. It reached around 78.66% and 99.02% of compressive strength from the control samples at 7th & 28th day. Besides that, the samples for batch QD10 in 75..m also show high compressive strength start at 14th day and 28th day which is 32.88MPa and 34.89MPa. To achieve the sustainable development goal and reduce environmental issue, granite quarry dust can be introduced in cement paste design as cement replacement which 10% and the particle size of quarry dust in 300..m or less than 300..m is recommended without compromising its quality.
