Good Quality M Sand is manufactured through a specific process of Crushing and gradation as per IS standards and free of all impurities like silt etc. Only few manufacturers have the required infrastructure to produce quality M Sand. Third Party testing can be done to check the quality of M Sand.
M sand can be adulterated in case when silt or fines are mixed to save cost and using this can lead to weak compression strength in case of concrete and can develop cracks when used for plastering.
Quarry Dust is a residue which is considered as waste. It is used only for manufacturing concrete blocks or post asphalting roads, they are of less than 2 mm thickness and not recommended and kind of construction activities. However it is sold as M sand and it appears similar.
The concrete mix proportions are same as river sand.
Not Required, however some professionals mix river sand with M sand.
If the plastering sand is between the range 0 to 2.36 mm, graded cubical and is free of dust and silt, then the cracks or any other problem will not arise.
M sand is sold in Metric Tonnes units. (MT) i,e 1000 Kgs.
The truck once loaded with M sand will be weighed in Manufacturer's calibrated Weigh Bridge. The load shall come with weightment slip along with the Delivery Note, however the weight can be cross checked at any closest weigh bridge near the site before unloading and after unloading to get the net weight, there could be a variation( +/-) of less than 3 % from weigh bridge to weigh bridge.
No, since the minute microns are washed away, the load weight of water wash M sand will be lesser than Dry M sand.
