compressive strength properties of different specimens. The compressive strength was obtained as per IS: 516 (1959)by testing on the mortar cube at 3, 7 and 28 days . The 28 days compressive strength of replacement of sand with quarry dust of mortar cube (CM 1:1) was 11.8% higher than the controlled cement mortar cube.
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.
F : Compressive strength of M with %, %, and % replacement for,, and days. quarry dust tested for days, days, and days is studied and the results are presented. With observation of % of quarry dust ( days), the average compressive strength is .N/mm 2 whereas that for natural sand is . N/mm 2.For %quarrydust,the value increased to .
Three replacement levels of 0%, 25% and quarry dust were used in the concrete mixes. The 25% is the optimum replacement percentage achieved by carrying out strength studies for 0%, 25%, 50%, 75% and sand replacement levels. The respective 28-day compressive strengths were 24.49, 27.91, 24.64, 21.33 and 19.40 N/mm 2 [18].
(c) The compressive strength results of quarry dust concrete (cubes) were obtained in the third series, where M20, M25, and M30 grades of concrete with 20, 25, and 30 percent replacement of quarry dust and also workability are studied by varying the water-cement ratio of 0.45 and 0.50 and the results are presented.
comparing the standard cement mortar strength with quarry dust based mortar it gives higher strength but the highest strength is achieved at B3 (106cells/ml) bacterial concentration that is 31.01 N/mm2 at 28 days. 4.2. Water Absorption Test For water absorption, after curing for 28 days put the cubes into oven at 85°c temperature for 24 hours
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 larger than sand and fineness modulus is higher than sand (1). Then adding with quarry
compressive strength is computed after 7, 14 & 28 days curing. At 30% replacement, the compressive strength is found to be higher than the remaining proportions. Hence maintaining 30% of quarry dust, dolomite powder is incorporated to replace cement at 0%, 10%, 20%, 30%, 40% & 50% respectively.
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 ...
Concrete grade C20 showed compressive strength increase of 40.58% for Dangote cement and 35.88% for Elephant cement with 50% quarry stone dust while quarry stone dust mix showed strength ...
The quarry dust and waste foundry sand's mass proportion of 80:20 had been defined as the optimal combination ratio for best compressive strength performance. A related study conducted by Verma et al. (2020), a form of quarry dust referred to as stone dust was utilized as a partial natural sand replacement.

The aim of this study was to compare compressive strength and mass of blocks made when EPS were mixed randomly or in layered manner in cement-quarry dust mortar. The EPS wastes were placed randomly and in a single layer so as to give percentage volume of 0% (control), 10%, 20%, 30%, 40% and 50% EPS of the cube of 150 mm. ...
The compressive strength of concrete with waste quarry dust included as cement replacement was evaluated at 7, 14, 28, 60, 90, and 120 days. In general, lower compressive strengths were obtained compared to their equivalent reference mix, as the waste quarry dust content increased for the constant water-to-binder ratio mixtures.
Fine aggregate was replaced up to 60% Quarry dust and evaluating its compressive and splitting tensile strength of Red mud concrete. The optimum gained after 7 and 28 days curing period was found to be 20% Red mud (for mortar) and for the combination of both Red mud and Quarry dust was found to be 20% Red mud + 40% Quarry dust(for …
quarry dust and fly ash in order to moderate the cost of mortar. The main objective of this work is to study the compressive strength of mortar cubes by various combinations of cement and fine aggregate replaced by Epoxy resin, fly ash, and quarry dust at the age of 7 days.
