Robosand Vs. Natural sand: a Trade-Off? – Avisun Properties
'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 …
