2007-7-19 From Fig. 2, it is found that the compressive strength of mortar is proportional to age of curing. When the quarry dust is added, the compressive strength is increased. This is because the quarry dust is stronger than sand. Moreover the seizing of quarry dust is

2021-7-13 The experimental program involves casting of geopolymer mortar cubes by using GGBFS, Flyash and Quarry rock dust and testing them at 1 day, 3 days and 7 days for compressive strength. Different parameter considered in this study is alkaline fluid to binder ratio Keeping 12-Molarity of the alkaline liquid and the ratio of sodium hydroxide to sodium metasilicate as constant(1:2).

2020-8-1 Table 1 reveals that the compressive strengths for layered were more compared to those of randomly mixed. This shows that compressive strength was directly proportional to mass. The compressive strength of the control sample had 18.67 N/mm2. This strength met the minimum requirements for mortar type M which should have a minimum strength of 17.2 N/mm2 as per ASTM C270. All the layered cubes had compressive strength in excess of 3.6 N/mm2 normally used for making concrete blocks. On the other hand, for random mixing all of them met the requirement except the 50% EPS substitution which had strength less than 3.6 N/mm2. It can be inferred from Table 1, that 40% EPS substitution randomly was the one that had the least density and met the strength requirement. This value is higher than 30% observed by. The difference could be attributed fine aggregate used. This study used quarry dust
