Robo sand is sand manufactured in stone quarries and it is a substitute for the river sand which is used in construction. Certain manufacturers are openly claiming that robo sand is a better alternative when compared to river sand. Listed below are few of the advantages of manufactured sand or robo sand:

Sand & Tray; Test Procedure. First, we have to fill the measuring cylinder with 1% solution of salt and water up to 50 ml. Add sand to it until the level reaches 100 ml. Then fill the solution up to 150 ml level. Cover the cylinder and shake it well (as shown in video) After 3 hours, the silt content settled down over the sand layer

Say, for example, sample sand that we are going to use has 30% bulkage of sand then we need to take 30% more sand that is 1.3 times of sand while volume batching in order to get 1 m 3 of sand for concrete. If we take 1 m 3 sand without adding bulkage then the sand volume lessen to 70% after adding water this is known as bulkage of sand.

The addition of Robo sand can reduce construction cost and also increase the strength of the concrete. Rice husk is by-product from crop growing waste and it is burnt to form Rice Husk Ash (R.H.A) which is used as partially substitute material for cement in concrete. In this study the concrete is prepared with RS as partially substitute ...

By substituting the fine particles with robo sand by percentages of weight, it is possible to assess the workability properties in terms of slump for M30 grades of concrete, i.e. (0 …

5. Robo Sand (RS): Robo sand is the sand manufactured in the stone quarries. Robo Sand is collected from crushing unit.(ABM PLANT). Robo sand was used as a replacement material for fine aggregate in the current experiment.The test results of Robo sand is tabulated in table 5. Table 5: Test results of Robo sand Colour Off white

B.Saleem basha et al /International Journal of ChemTech Research, 2017,10(4): 345-351.346 Usage of robo of sand as the remedial measure to the river sand, robo sand will give the good results in terms fluidity and strength is nearly same to both up to some percentages [12].

ROBO sand: ROBO sand or crusher dust obtained from local granite crushers was used in concrete to cast the cubes and cylinders. The bulk density of ROBO sand or crusher dust is 1768 kg/m3. The specific gravity and fineness modulus of ROBO sand are 2.66 and 2.88 respectively. Sieve analysis results are shown in Fig. No. 2

'River sand' has been used for concrete mason work, and requires very little water. River-sand or natural-sand has better texture, is smooth and round in shape with extremely low 'silt' and 'clay' content. 'Silt' is super fine material that is not good for construction. 'River sand' contains very less of silt making it an ideal raw material for …

Parameters: M Sand: River Sand: Process. Manufactured in a factory. Naturally available on river banks. Shape. Angular and has a rougher texture. Angular aggregates demand more water.
