Check sand quality
While taking up construction and ordering for material in the process, do keep an eye on the quality. Sand is a key construction material and it is imperative that the load that is dumped at the construction site is a quality one.
Good sand is one that is clean and coarse and free from either organic or vegetative matter.
Sharp and angular grains are what you should go for. Experts suggest that the sand should be well graded and does not come with silt and clay. It should also be free of salt that attract moisture.
The varieties available include pit sand, river sand and the one brought from seashore.
Pit sand is coarse with normal reddish yellow colour and is usually used in concreting.
Obtained from river beds, the river sand is considered to be fine, consisting of rounded grains and is used for plastering.
