quarry dust with cement gives the compressive strength of 41.5Nmm2 and after that it goes on decreasing when compared to conventional without any replacement of quarry dust. It is clearly observed that addition of quarry dust up to certain extent will increase the compressive strength of concrete. Er.

but quarry dust is useful for construction work as sand. If we mix quarry dust in sand then only 65 to 75 of sand replaced by quarry dust because strength of concrete is affected by this process. In other process if we mix quarry dust and fly ash are added together in concrete mix then we replace complete sand by quarry dust and fly ash. The

concluded that the compressive strength of concrete, with 50 Sand and 50 quarry dust Mix 3, under thermo shock and high temperature showed the least reduction in strength. It was finally concluded that quarry dust can be effectively used for 50 replacement of sand in the conventional concrete. Utilization of Quarry Dust as Fine Aggregates

Top Benefits of Using Quarry Dust in Construction Project As compared to sand and cement, the quarry dust is easily available. It requires less processing and it being a byproduct of quarrying, it is very accessible at large quantities for a cheaper cost. Many quarry owners dispose it at very low prices making it almost always available.

Since quarry dust is a waste material from quarries and shows pozzolanic characteristics, it is always encouraged to use quarry dust for stabilization where easily and economically available. Quarry dust is extracted from the quarries is a nonplastic fine silt. Its composition varies according to blasting done in quarries.

to study the effect of partial replacement of fine aggregates by quarry dust and cement by fly ash on cement concrete. 1.2 NEED FOR INVESTIGATION Quarry Dust These residues are generally less than 1 aggregate production in the normal concrete. The introduction of quarry dust for mixing is limited due to its high fineness.

Abstract. This paper presents the results of an experimental investigation carried out to evaluate the compressive strength and transverse strength of 1 3 mortar mixes in which natural sand was replaced with 20, 50, and 100 quarry dust by weight which were further modified by partially replacing cement with four percentages 15, 20, 25, and 30 of low calcium fly ash.
