replacing the cement and fine aggregate by eco sand the disposal problem of e co sand is prevented and the exploitation and depletion of natural resources such as river sand can be conserved Many researches indicate that the replacement of fine aggregate by eco sand enhances the compressive strength of concrete 2 L ITERATURE REVIE W glass reuse as fine aggregate in concrete Using waste glass in the concrete construction sector is clean river sand with maximum size of 4 75mm conforming to zone II as per IS383-1970 [9] with Experimental Investigation Of Waste Glass Powder As The Partial Replacement Of Sand In Making Concrete Author: Vijaykumar G Sawant

Feasibility study on utilization of marine sand in

Concrete is normally developed using river sand as fine aggregate In this work M30 grade of concrete has been developed by the mix proportion of 1:1 22:2 54 with water cement ratio 0 42 In this proportion 1 22 parts of fine aggregate is partially replaced with sea sand

Properties of Concrete with Coconut Shells as Aggregate Replacement Intell Engineering College Anantapur India Abstract––Properties of concrete with coconut shells (CS) as aggregate replacement were studied Control concrete with coarse aggregate Well graded river sand passing through 4 75 mm was used as fine aggregate The

Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand gravel or crushed stone) a binder (natural or synthetic cement) chemical additives and water Although people commonly use the word cement as a synonym for concrete the terms in fact denote different substances: cement

replacement of fine aggregate for concrete making is need to develop alternative materials for replacing Page 17 natural river sand in concrete [1] For reducing the usage of the raw material large replacement is done using the various

Constituent Materials of Concrete Very fine particles of fly ash can improve the flow characteristics of concrete reduce costs by replacing cement require less water in the mix and make concrete more dense Double-washed sand The maximum size of aggregate should be less than one-fifth of the narrowest dimension between the sides of

Comparative Study on performance of concrete with

Comparative Study on performance of concrete with Natural sand and Robo sand Generally river sand is most used as fine aggregate in concrete for construction River sand is becoming scarce due to the properties of concrete by replacing the fine aggregate with quarry dust M20 M30 M40 grade concrete

The use of quartz sand as replacement for sand is an economical solution for making the concrete resistant to weathering The paper presents a concrete mix design procedure for partial replacement of sand with quartz sand Coarse aggregate consists of rounded river gravel crushed stone or manufactured aggregate with particles of size equal

natural aggregate deposits called pit-run gravel consist of gravel and sand that can be readily used in concrete after minimal processing Natural gravel and sand are usually dug or dredged from a pit river lake or seabed Crushed stone is produced by crushing quarry rock boul-ders cobbles or large-size gravel Crushed air-cooled

Concrete is the most widely used man-made construction material in the world It is obtained by mixing cementing materials water and aggregates and sometimes admixtures in required proportions The use of river sand as fine aggregate leads to exploitation of natural resources lowering of water table
