Keeping the water cement ratio at and and using super plasticizer (at 15ml per kg of cement) the slump values were determined for both M20 and M25 mixes using river sand and Msand as fine aggregate.
May 2 2022The main aim of the study is to determine the degree to which dredged offshore sand can be used as a substitute for river sand by testing its physical chemical and structural characteristics. Experimental investigation on the use of offshore sand as a partial substitute for river sand in concrete AIP Conference Proceedings 2463 020025
The use of crushed rock sand as a partial replacement of river sand in concrete production was and for 0 to 100 natural sand replacement. The slump ranged between 49 and 60 mm for 0 to 100 natural sand replacement.
Seawater and sea sand are used in concrete to reduce the consumption of freshwater and river sand. To improve the mechanical properties and cracking resistance of concrete polymer fiber is commonly used. In this study polyoxymethylene (POM) fiber was innovatively applied to seawater seasand concrete (SWSSC) and the workability earlyage cracking behavior and mechanical properties of

AlJabri et al. 41 stated that up to 40 substitution of sand by copper slag shows a diminishing in the surface water absorption and after that the water absorption quickly increases. U. 2016. Isand An environment friendly alternative to river sand in Reinforced Cement Concrete constructions. Construction and Building Materials. 125
Sand (MSand) and Quarry Dust Sand as a substitute for river sand become inevitable. To overcome from this crisis fully many areas maintain practical option for concrete river sand. Physical Properties of Fine Aggregate PROPERTIES TEST VALUES RS MS QS 1 Specific gravity
The results exhibits that 6080 replacement of FeCr slag against normal river sand in cement concrete is the optimum substitution considering compressive strength. This shall add to safe disposal
Difference Between M sand and River sand. Concrete with m sand has very poor permeability as compared to river sand. But when river sand is used in concrete the permeability of concrete is less poor as compared to river sand. It has more water absorption 2 to 4 . Whereas water absorption of river sand is less to 3 .
Manufactured Sand or Crushed Sand is the environmentalfriendly solution that serves as a perfect substitute for the fast depleting and excessively mined river sand. Msand has crushed aggregates produced from hard granite stone which is cubical shaped with rounded edges. The appropriate quality of rock suitable for construction is used for
Mar 24 2016 River Sand Substitutes for Concrete Production and Cement Sand Mortar Production (Phase One) Final Report (Phase One Final Report) in April 2013 identifying suitable river sand substitutes for practical applications in the local construction industry. After completion of Phase One study four new standards were published.
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 microns to mm in proper proportion). Demand for manufactured fine aggregates for making concrete is increasing day by day as river sand cannot meet the rising demand of
Overall M Sand is 30 cheaper than the river sand. Ecofriendly Use of M Sand in replacing with river sand avoids environmental disasters like groundwater depletion water scarcity a threat to natural life etc. Growing concern for environmental protection M Sand is the best alternative to the river sand.

Aug 10 2017· Re Substitute Material For Construction Sand There has been such a demand for sand down here companies have sprung up in Mexico that have been going into the arroyos and canyons and stripping them of all of their sand which has had horrible consequences turning these places
Oct 7 2022Quarry dust has some potential as a fine aggregate substitute for river sand in the construction of concrete. It is essentially a byproduct of stone crushers created during the coarse aggregate crushing and screening process. The compressive strength of the concrete is somewhat improved when quarry dust is used in place of river sand.
The percentage passing 150 microns of manufactured sand is relaxed to 20 (while that of natural sand is limited to 10 ). As per design and economics crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.
a. Concrete Sand. For use in concrete pavements bridge decks precast pavers or any other item used in concrete highway wearing surfaces sand (natural or manufactured) must contain at least acidinsoluble residue in the plus 600 µm size fraction and in the minus 600 µm size fraction. Sands may be blended to meet this requirement. b.
