2017 aggregate production analysis
In 2016, crushed stone production reached 1.36 billion metric tons. While overall production of crushed stone dipped in 2017, the average value per metric ton has increased by $1.51 – or 15.2 percent – since 2013. Apparent consumption of crushed stone also dropped by a small margin in 2017, totaling 1.39 million metric tons, compared to 1

In-situ compressive strength of demolished building concrete has been measured by the Non-destructive test (NDT) core testing. In the present research work, recycled crushed sand (RCS) was substituted by natural dune sand (NDS) in the ratio of 40%, 100%, and 80% in mixes 40NDSC, 100RCSC, 80RCSSDC, and 80RCSCRC, respectively.

Testing of Sand Quality at Construction Site for Concrete
Quality of sand is as much of importance as other materials for concrete. Aggregate most of which pass through 4.75 mm IS sieve is known as fine aggregate. Fine aggregate shall consists of natural sand, crushed stone sand, crushed gravel sand stone dust or arable dust, fly ash and broken brick (burnt clay).

Crushed Sand vs. Natural Sand: Make the Right Choice!
Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Crushed sand contains a larger amount of micro- fine particles. This can affect the strength of concrete.

CONCRETE MIX DESIGN USING CRUSHED SAND
From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and 28 days respectively.

Aggregates for Concrete
Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of
