Alternative Sand: An Inevitable Resource to River Sand

Many researchers have found that 30% replacement of river sand (RS) with recycled fine aggregate (RFA) is more suitable [15, 16]. However, utilizing RFA produces low density concrete and RFA increases mechanical properties of the concrete with appropriate proportion of superplasticizer. Kou et al. [16] found that 10% replacementEffect of replacement of River sand by M-sand in high,,river sand. M -sand is obtained as a crushing of granite stones in required grading to be used for construction purposes as a replacement for river sand. M -sand has been used in large scale in highways as surface finishing materials and also used in the manufacture of hollow blocks and in light weight concrete prefabricated elements. In this, investigations were carried out to study the,Replacement of River Sand by M Sand Concrete,Replacement of River Sand by M Sand Concrete Dr. M. Kannan HOD CIVIL-PITS Fantin Jesanth.

Alternatives to river sand for construction

14/12/2013· Today researchers world over are in continuous search for the alternatives to river sand. Fine aggregate is one of the important constituents of concrete. River sand is becoming very scarce and sand mining from rivers has become objectionably excessive. It has now reached a stage where it is killing all our rivers day by day so sand mining has to be discouraged by the engineers for all type of,Stone Dust in Concrete: Effect on Compressive Strength,natural river sand for future generations. In the present investigation, an experimental program was carried out to study the workability and compressive strength of concrete made using stone dust as partial replacement of fine aggregate in the range of 10% - 100%. M25 grade of concrete was designed usingIndex Terms IJSER,partial or full replacement to river sand is the need of the hour as a long term solution in Indian concrete industry until other suitable alternative fine aggregate are developed. In the present study, a comparison of the Compressive strengths of River Sand and M-sand is done with the hundred percent replacement of river sand by M sand. Index Terms — M-Sand, Compressive strength, fine,
