Concrete is a mix proportion of cement, sand and aggregate. sand by artificial sand causes reduction in compressive strength of concrete mixes with increase
river sand which is used as fine aggregate for making concrete becomes scarier and poses environmental problem. Artificial sand used as alternative to natural
12 Feb 2015 Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly
sand and demolished concrete structural aggregates on compressive strength and workability of concrete. Artificial sand is manufactured from crushing of local
The artificial sand produced by proper machines can be a better substitute to river sand. The sand must be of proper gradation (it should have particles from 150
4 Feb 2015 To the author's knowledge, currently there are two brand-named crushed sands: the Advanta® engineered concrete sand produced by Luck
The strength of aggregate will affect the strength of concrete. Due to scarcity of natural sand, it is necessary to find suitable substitute for this valuable material.
For the purpose of experimentation concrete mixes are designed for M20, M30 and M40 grades by 100% replacement of natural sand to artificial sand.
Both concrete made using artificial sand and natural sand are moderate to chloride permeability. III. EXPERIMENTAL INVESTIGATION. 3.1. Cement
Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher
21 Apr 2021 Artificial sand and mixed sand are mainly used in building construction, municipal construction, transportation, and other projects whose concrete
7 Dec 2012 Review of Artificial Sand and Artificial Sand Concrete[J]. Science and Technology of Overseas Building Materials, 2004, 25(3):20–24.
In this paper an attempt is made to utilize recycled concrete aggregates and artificial sand (machine made sand) in concrete, using IS10262:2009 as guideline.
About. 37.5 % volume of concrete is comprised of sand. A good class concrete is produced by cautious mixing of cement, fine and coarse aggregates, water and
KEYWORDS: River sand, Crushed sand, mix design compressive strength of concrete. I.INTRODUCTION. The Main ingredients of concrete are cement, sand, and
An attempt have been made to examine the suitability of replacing the 30% of. Fly Ash and 50% of Artificial Sand for a concrete of grade M35. Examine strength
On this aspect research on concrete with manufactured sand is scarce, green sand, robo sand, poabs sand, sand, pozzolana sand, and artificial sand.
At a same level of strength, the use of crushed sand has shown good results. Concrete with water/cement ratios of 0.55 and 0.60 with a crushed sand content of 60
Artificial sand is a process controlled crushed fine aggregate produced from quarried stone by crushing or grinding and classifiion to obtain a controlled
artificial neural networks (ANNs) to predict the compressive strength of recycled aggregate concrete. ANN model is constructed, trained and tested using 146
Evaluated also was the effect of replacing 5% of the cement by silica fume in the concretes with artificial sand. The only parameter set for grain structure was the
This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune

Crushed sand as replaced materials to natural sand has become beneficial and is common in the world. Different researchers have carried out research to study
Three trials are carried out for each water cement ratio and concrete mix proportion, where Mix 1 is the reference mix with 20% manufactured sand, Mix 2 is with 40
2 Jan 2017 Test results indied that crushed stone dust waste can be used effectively to replace natural sand in concrete. Concrete made with this
24 Dec 2010 Concrete is an artificial conglomerate stone made essentially of Portland cement, water, sand and coarse aggregates. The mixture of the
The strength of aggregate will affect the strength of concrete. Due to scarcity of natural sand, it is necessary to find suitable substitute for this valuable material.
materials is artificial sand (wash/foundry/crush sand). Using. M-20 grade proportion of this wash sand along with sand the required concrete mix can be obtained
Concrete is a composite material composed of fine and coarse aggregate bonded together with Fine and coarse aggregates make up the bulk of a concrete mixture. Sand, natural gravel, and crushed stone are used mainly for this purpose.
