Sea sand and robo sand are the alternate material for exhausting river sand. Sea sand is very cheap in cost and easily available in coastal area but it contains alkali matter and impurities which are not good in concreting. This sea sand can get washed and used for many constructions. Robo sand is the one of the alternate material for river sand.

As a substitute to river sand, Robo sand has been used. In this present experimental study a comparative study has been carried out to check the usability of Robo sand in place of natural sand. This study involves determination of some major properties of concrete like compressive strength, split tensile strength, flexural tensile strength and ...

The properties of particle shape, consistent gradation and zero impurities are the reason for the preference by structural consultants and concrete technologists. The imperative need for clean sand, eliminating the constraints of river sand like availability, price fluctuation etc, have made manufactured sand the perfect substitute for river sand.

These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary. Thus required grade of sand for the given purpose helps the concrete fill voids between coarse aggregates and makes concrete more compact and dense, thus increasing the strength of concrete. ...

This document discusses different types and properties of sand. It describes sand as a mixture of small rock and mineral particles between 0.06 mm and 2 mm in size. The main components of sand are quartz and feldspar. Sand comes in different colors depending on its mineral composition, and there are various types including river sand, sea sand ...
