For mixes M20 and M25, quarry dust concrete with water cement ratio 0.65 showed same slump as that of control concrete with w/c 0.5 [28] In view of the above studies, following observations are
B. Stone Quarry Dust . There are number of Stone quarries in Margalla Hills around Taxila city. For this case study we brought the Quarry dust from one of the Stone Quarries in Margalla Hills. The quarry is known for producing Basic aggregates. The dust of these Quarries is effecting 5-10 Km. 2. surrounding area. The properties of the quarry
This is the "binder" in the concrete and composes 7-15% of the total concrete weight. The rest is aggregate: sand, gravel, etc. When you order concrete delivered by truck, they ask "How many sacks?" This means how many (usually 80 lb.) sacks of Portland Cement do you want mixed into each cubic yard of the concrete.
Stone dust is also known as rock dust or quarry dust, and some products just have the brand name. The stone dust is collected using a screen that keeps the larger pieces of crushed stone above the screen while allowing the rock dust to fall through. This process is the reason why stone dust is often called quarry screenings.

Manufactured sand is produced by the crushing of hard rocks and during this process, about 25% of the stone is converted into fine dust called quarry fines or quarry dust (QD). Most of the quarry dust is formed while devastating, crushing and screening of extracted rock to make fine aggregate and other products.
Most commonly, stone dust is used for paving projects such as driveways, patios, and pathways. Many landscapers prefer to use sand with concrete as the base material and to use stone dust only for between the paving stones.

In one more investigation where natural sand is replaced 100% with quarry dust to study the physical properties, mechanical properties and durability of concrete made by quarry dust with done by R. Ilangovana , N. Mahendrana and K. Nagamanib [7].Mix design has been developed for M20, M30 and M40 grade of concrete for both conventional concrete
Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.
erosion of rocks produce particles of stone, gravel, sand, silt, and clay. Recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. Conven-tional stone crushing equipment can be used, and new equipment has been developed to reduce noise and dust.
Quarry dust a by- product from crushing process during quarrying activities is good alternative during construction projects. It is used as substitute to sand to make quarry dust concrete which is believed to be stronger and more durable than the regular concrete materials. Uses of Quarry Dust. It can be used as substitute to sand wholly or partly.

The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and
(Quarry) Using natural rocks (such as limestone, granite, basalt, etc.) mined as raw materials, aggregates made by physical crushing are called natural aggregates, such as sand, crushed stone, gravel, etc. It is an important part of concrete and is widely used in urban road engineering, bridges, buildings and other infrastructure fields.
In contrast to stone dust, concrete sand provides superior performance over time. It doesn’t eat away at pavers, it affords excellent drainage, and it compacts well. The coarse texture also acts to hold pavers in position, providing a stabilizing buffer that allows the ground underneath to shift without shifting pavers.
Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to 100% in step of 10%.

usage of quarry dust as 60:40 proportion of substitution of natural sand i.e (quarry dust replaces 60% of natural sand) in concrete. Silica fume is added as mineral admixture by 15% of weight of cement and steel fiber used in different percentage (0.5%, 1.0%, and 1.5%) to increase the tensile strength.

found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., 2015). In the present study it is proposed to investigate the optimum replacement of river sand with stone dust for concrete in term of compressive strength performance at 7 days and 28 days. II.

The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price. Thus an increased need to identify a suitable substitute, that is eco-friendly and inexpensive quarry dust being extensively used as an alternative to the sand in the production of concrete. In this paper an attempt has been made to determine the

sand and one of the major materials is quarry stone dust. By the using of quarry stone dust make a proper mix of concrete with a satisfactory strength. In this research paper we use different alternate material of sand and use in sand in different proportions and check their characteristics with sand.
The use of quarry dust is also in concrete is also a measure necessary for improvement of concrete strength. River sand was replaced with quarry dust for different mix designs of concrete for 0% to 25% replacement levels with 5% intervals. The physical properties of river sand and quarry dust were tested and reported and the workability as well
