Due to the continuous usage of natural resource such as river sand in concrete, the demand increases inevitably regardless of usage. The abundant production of quarry dust from stone crushing units as a waste product is becoming problem for its disposal. Due to the scarcity of natural sand is overcome
Aggregates, both fine and coarse, take about 6575% by volume of concrete and are important ingredients in concrete production. The parent materials of aggregates are derived mainly from volcanic activity. The dominant rock for coarse aggregate production in Ethiopia is generally basalt while ignimbrite is most commonly used for masonry stone.
Classifiion of Sand: According to the size of grains, the sand is classified as fine, coarse and gravelly. ADVERTISEMENTS: The sand passing through a screen with clear openings of mm is known as the fine sand. It is mainly used for plastering. The sand passing through a screen with clear openings of mm is known as the coarse sand.

The main objective of this research was to investigate the feasibility of using ground vehicular tyre (GVT) as a partial replacement for sand in the production of concrete pavement blocks. In this study cement, sand, quarry dust, coarse aggregate, and ground ... Save Eastern Network Library 158 PAGES (32718 WORDS) Design and Technology Thesis
Crushed concrete of 520mm in size contain on average % of dust and silt particles while in crushed stone of 4070mm the percentage of such particles increases up to % that corresponds to grade 600. When building materials are reused for production the amount of dust and silt particles increases.
Using quarry waste as a substitute of sand in construction materials would resolve the environmental problems caused by the largescale depletion of the natural sources of river and mining sands. This paper reports the experimental study undertaken to investigate the influence of partial replacement of sand with limestone waste (LSW), as an additive on the concrete .

addition of granite dust as replacement of natural sand may be due to the filling effect of granite dust due to its high fineness as compared to natural sand. Ganesha Mogaveera. G. Sarangapani and Anand V. R.   have studied the effect of Partial Replacement of Sand by Quarry dust in Plain Cement Concrete for different mix proportions ...
· The natural river sand and natural rocks are the other materials in concrete. The design of the building and construction structures depends on the cost, lifespan and performance. The aggregates also contribute 1% of CO 2 emission in a typical cubic meter of concrete structures materials.
In the present investigation we design mix for M30 has been calculated using IS 10262 2009 for both conventional concrete and partially replaced concrete. Tests were conducted on cubes, cylinders and beams to study the strength of concrete by using GGBS and quarry dust and the results were compared with the Natural Concrete.

Following are the tests for sand at construction site: Organic impurities test – this test is conducted at the field, for every 20 cum or part thereof. Silt content test – this is also a field test and to be conducted for every 20 cum. Particle size distribution this test can be conducted at site or in laboratory for every 40 cum of sand.
· For the preparation of concrete, ordinary Portland cement was used with the chemical composition as tabulated in Table river sand having (density of g/cm 3) and gravel (20 mm and 10 mm) having (density of g/cm 3) were used for the preparation of concrete, collected locally from Nagpur, polycarboxylate based superplasticizer .
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at billion to billion tonnes a year for 2012 alone.
· Mortar Mixes. Two control mixes, namely, 1 : 3 cement sand mortar mix, QC series, with 0, 20, 50, and 100 percent partial replacement by weight of natural sand with quarry dust and 1 : 3 cement sand mortar mix with 20% partial replacement by weight of natural sand with quarry dust which was further modified by replacing 0%, 15%, 20%, 25%, .
coarse aggregate in concrete. Its proportions of replacement are 0%, 20%, 40%, 60%,80% and by mass of coarse aggregates. As demolition is the final stage of the life of any construction, this project aims to look at ways the waste materials generated from demolition especially waste concrete can be reused as course aggregates.
Experimental Investigation on replacement of Sand by Quarry Dust in ConcreteMain Paper K. Mamta, Mr. Ahsan Rabbani *** Abstract Now a days the utilization and consumption of natural aggregates and cement as largest concrete component is rapidly and constantly increasing in the production of concrete.
Advance concrete technology can reduce the consumption of natural resources and energy sources thereby lessen the burden of pollutants on environment. We describes the feasibility of using the marble sludge dust in concrete production as partial replacement of cement. Presented by Rahul,Jamsheed, Shanil, Geo, and Jagdeesh, under the guidance of Miss; .
Partial replacement of ingredients by using waste materials and admixtures shows better compressive and tensile strength, improved sulphate resistance, decreased permeability and improved workability. The cost per unit volume of concrete with waste materials like quarry dust is lower than the corresponding control concrete mixes.
