In this study researchers investigated the influence of fineness of locally available basaltic volcanic ash (VA) and its blend with other potential supplementary cementitious materials (SCMs) on compressive strength of mortar. Local quarry sites and steel making industries in the eastern province of Saudi Arabia produces tons of wastes …
Itcan be due to the extra fineness of quarry dust. Increased fineness require greater amount of water for the mix ingredients to get closer packing, results in decreasedworkability of the mix. ... The test is carried out on 150x150x150 mm size cubes, as per IS: 516-1959. The test specimens are

Quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement (Balamurgan et al., 2013). While using crushed stone dust as fine aggregate in concrete it is found that there is increase in compressive, flexural and tensile strength of concrete (Nagpal et al., 2013). It has ...

To test sand on site, a glass of water with the sample of sand can be stirred and left to settle. After an hour, if coal dust in the sand has settled, it indicates good quality without silt or clay particles. Another test involves mixing the sand with sodium hydroxide solution to check for organic impurities which may cause a color change to brown.
