replacement of fine aggregate by quarry dust in various percentages and also the effect of partial replacement of cement by fly ash at the time of preparation of SCC. Coarse aggregate of size 20mm maximum size and minimum powder content up to 400kg/m. 3. without VMA is used.

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).

utilize. The quarry dust is used as the first fine aggregates. 3. Since sand is much costlier due to reduction of sources IV. Sand: as natural fine aggregate, we need to find a replacement Sand is used as the second fine aggregates. The locally product with less cost.

 · To overcome the difficulties due to excessive sand mining, quarry dust was used as fine aggregate. Quarry dust is the fine material, produced from gravel crushers. Super plasticizers were used to improve workability of concrete. Cement was replaced with 10% of silica fume. The M60 grade concrete used was designed by using a modified ACI method ...

Quarry Dust as a Fine Aggregate in Cement Mortar Shivkumar Srigiri1 Sridhar P Gadwal2 Shrishail Mane3 Shruti kobhal4 Prof. Tanveer Asif Zerdi5 1,2,3Department of Civil Engineering 1,2,3,4, college of Engineering, Gulbarga Abstract— In this experimental work ninetynine cubes has been prepared having dimension mm are

In this study the properties of concrete with quarry dust as fine aggregate is studied to find out its suitability to replace river sand in structural concrete. Furthermore, use of fly ash with 30% of cement replaced by fly ash is explored as means of increasing the performance of the quarry dust .

An increase in compressive strength was observed up to 30% replacement of fine aggregates by Quarry dust and there after decreasing. The maximum compressive strength measured was 26% more than that of reference mix at 28 days corresponding to concrete mix containing 30% quarry dust in place of fine aggregates.

The results were compared for concretes with natural sand to that of quarry stone dust as fine aggregate. COMPRESSIVE STRENGHTS (M25 GRADE): The compressive strength of M25 grade concrete cubes made with natural sand and those made with quarry stone dust as fine aggregate are tested under compression testing machine and results are tabulated in table shown below

Nevertheless, such quarries still need to ensure that the amount of inhalable dust does not exceed 10mg/m3 over an 8hour period and exposure to respirable dust should not exceed 4mg/m3. Anyone operating or managing a quarry is required, under Health and Safety Executive (HSE) guidance, to reduce the exposure of staff, contractors and those living near a plant to silica dust .

2) Quarry dust: Quarry dust an alternative for sand is collected from nearby quarry. Quarry dust was tested as per IS: 2386 (Part 1 and 3) 1963 and IS: 383 properties of quarry dust are tabulated in Table III. Fig. 1: Quarry Dust Table 3: Properties of Sand and Quarry Dust S. No. Properties Sand Quarry dust

The coarse aggregate particles are usually crushed stone or crushed gravel, and the fine aggregate particles are usually natural sand. Crushed Fines Acme Sand Amp Gravel. Crushed Fines and also known as Quarry Dust, is a form of fractured gravel chips and fine dust used to solidify the base under patios and walkways.

An Experimental Study on Replacement of Fine Aggregate with Quarry Dust. Mohammed Arbaz Khan, S. Zubairuddin, Mohd Arfath Khan. Abstract. The rapid growth in development of construction industry is leading to an increase in utilization of natural resources like river sand due to which there has been a much scarcity in availability for construction.

The suitability of quarry rock dust to replace fine aggregate in concrete mix needed to be identified. PROBLEM STATEMENT River sand which being used as fine aggregate in concrete industry are usually washed and graded at the pit or plant. The cost for the river sand treatment are expensive

 · The compressive strength of concrete built with river sand and quarry dust as fine aggregate was examined in this study. Ordinary Portland cement (OPC) was blended with river sand and quarry dust at five levels, namely 10%, 20%, 30%, 40%, and 50%, by partially substituting OPC with river sand and quarry dust.

Index Terms—GGBS, quarry dust, calcium nitrate, compressive strength, durability, corrosion resistance . I. INTRODUCTION Concrete is the most widely used building material in the world due to its versatility, low cost and durability. Fine aggregate is an essential component of concrete. The most commonly used fine aggregate is natural river sand.
