Which sand is best to obtain High PSI strength of concrete?
Best Construction Sand in Pakistan
Concrete Sand is a course sand that is washed and screened to a larger grit than Masonry Sand.
Lawrencepur sand is best for the concreting purpose, we generally use it as coarse sand.
The most demanding concrete sand to gain high strength by using small quantity of cement by Ready-Mix Concrete Batching Plants in Pakistan is Sand Lawrencepur, Harrow Sand.
Lawrencepur sand is used in mix of 24.5 MPa (3500 psi), 28 MPa (4000 psi) and 35 MPa (5000 psi) to achieve required strength of concrete.
The Lawrancepur sand comes from Lawrence pur Disttrict Attock, Punjab, Pakistan by Quarry and it is extensively used in Punjab region due to its superior quality and strength.
its size range from 2.36mm to 0.5mm and It is lab proven and all construction material testing laboratories in Pakistan including UET's.
