·Many studies have been performed on the use of waste foundry sand in concrete and concrete related items such as replacement of aggregate fine and bricks blocks and paving stones
grades of concrete by replacement of sand with quarry dust Key Words Concrete Compressive strength Quarry Dust Replacement Sand 1 INTRODUCTION Quarry dust is a by product releases from the cutting and crushing process of stone which is a concentrated material to use as fine aggregates By exploding mountain rock will be crushed to
·General about Stone Dust Stone dirt is a waste cloth acquired from crusher plants It has capacity to be used as partial replacement of natural river sand in concrete Use of stone dirt in concrete no longer handiest improves the fine of concrete however additionally preserve the herbal river sand for destiny generations
dust as a partial replacement of sand by stone dust The present research s aim is to find out the optimum percentage of stone dust while designing a mix of an M20 grade of concrete The sand is
·It was observed that the slump values increased with increase in percentage replacement of sand with quarry dust The compressive strength of cubes at 28 day curing for control mixture of 1 3 6 at
·To accomplish this an experimental programme was planned for cast specimen cubes at an interval of 10 percent replacement of fine aggregate with stone dust in concrete Results shows natural sand
·Using stone dust from 10 50% as a replacement for sand can increase the compressive strength of concrete cubes by 8 27% at 7 and 28 days However workability decreases with higher replacement levels requiring a higher dosage of superplasticizer This increases the cost of the concrete by 5 8% Stone dust meets Indian standards for use as a
sieve is used as cement replacing material and retained by No 100 sieve is used for sand replacement Sand was replaced by stone dust of 15% 20% 25% 30% 35% 40% 45% and 50% by weight of
·Thus a detail investigation is to be needed for evaluation of CSD as alternative of natural sand or fine aggregate This study is focused on the nominal mixes were prepared for grades M 20 and M 30 of concrete basic of Indian Standards codes using natural sand NS and replacement of NS sand with crushed stone dust CSD in different proportions
·Stone dust passing by No 200 sieve is used as cement replacing material and retained by No 100 sieve is used for sand replacement Sand was replaced by stone dust of 15% 20% 25% 30% 35% 40
·Fresh ceramic waste coarse aggregate and quarry dust fine aggregates make concrete less cohesive and harder to deal with than standard concrete [16] Ceramic waste and quarry dust aggregates absorb much of water This technique uses porous ceramic waste and quarry dust aggregates Stone dust can substitute river sand as fine aggregate in concrete
·CEMENT BY FLY ASH AND FULLY REPLACEMENT OF SAND BY STONE DUST Kumar Reddy 1Assistant Professor 2 Professor 3Assistant Professor 1Department of Civil Engineering 1NBKR Institute of Science & Technology Nellore India
·sand and in the same way natural sand is partially replaced by Stone dust from 30% to 50% distance varies from 10% by weight to natural sand 36 mixes test mix control mix and variation mix were made for the M30 and replacement with stone dust by weight of OPC was measured International Journal For Technological Research In Engineering
·alternative material to natural sand Some alternatives materials have already been used as a replacement of natural sand such as fly ash quarry dust or limestone and siliceous stone powder filtered sand copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand Chandana Sukesh et al 2013 [9]
·Equivalent mixes are obtained by replacing stone dust partially/fully Test results indicate effective usage of stone dust with same compressive strength comparable tensile strength and modulus of rupture Workability of 40% replacement of stone dust with 2% Superplasticizer is equal to the workability of conventional concrete Workability is
·He concluded that 25% of granite dust as sand replacement exhibited % to % increase than control mix and it was optimum amount to get favourable strength Even at 100% replacement of natural sand with granite dust the increase in flexural strength observed was % % for various curing ages
·PARTIAL REPLACEMENT OF FINE AGGREGATE WITH SAWDUST FOR CONCRETE Albert M Joy1 Aayena K Jolly2 Anju Merin Raju3 Bobina Elizabeth Joseph4 Dept of CE Amal Jyothi College of Engineering Kanjirapally ABSTRACT The importance of concrete as construction material is increasing every day Sand as a primary fine
2 Stone dust as a part replacement material of sand in concrete Many researchers have done researches to find out the effect of stone dust to replace part of sand in concrete mixture [9 15] Sankh at all [15] found that many alternative materials such as copper slag ground granulated blast furnage slag ggbs washed bottom ash quarry dust
·sand in construction works has assumed greater importance now a days Researcher and Engineers have come out with their own ideas to decrease or fully replace the use of river sand and use recent innovations such as M Sand manufactured sand robot silica or sand stone crusher dust filtered sand treated and sieved silt removed
·However quarry dust has been used as fine aggregate for either partial or total replacement for river sand in concrete and mortar production toward improving environmental sustainability [22][23
