Abstract: Excessive extraction of raw material for the production of cement causes the depleting of the raw material besides damaging the landscape. Therefore, an alternative solution needs to be looked into in order to reduce the usage of cement in the construction industry. With that in mind, Micro Fine Quarry Dust (MFQD) is a white material which is a buy product from the quarry is introduced to replace cement. In this paper, the replacement of cement by MFQD in concrete mixture seen to be a reliable source in terms of strength and its rate of water absorption. There were five (5) percentages of replacement of cement with MFQD which are 3%, 5%, 10%, 15% and 20% and tested at 7, 28, 60 and 90 days after water curing. The concrete mixture was prepared using 0.6 and 0.3 w/b ratio. The results showed that the replacement of MFQD up to 15% can improved the strength of the concrete, since the mixed from both w/b ratios achieved the targeted strength. While, in term of water absorption, the highest MFQD replacement is at 20% in which the rate of water absorption was below than 10% by mass. From this study, it shows that about 20% of MFQD can be used to replace cement.
