Fundamentals of Concrete

paste needed to make concrete using the aggregate. For instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is needed to fill voids and cement the particles together than would be needed for a coarser sand. Below is an example of the mechanical sieve analysis results of a fine and coarse

How sand is made

The production of sand for construction purposes grew significantly with the push for paved roads during World War I and through the 1920s. The housing boom of the late 1940s and early 1950s, coupled with the increased use of concrete for building construction, provided another boost in production.

production of concrete sand

Which Sand Do I Need? SoilWorx. Concrete Sand. Concrete sand is a naturally occurring material with a nominal size of generally less than 5mm. Typically washed and screened during the production process, the sand has a larger particle size with aggregrates through it which means it significantly improve drainage and soil structure when mixed through heavy soils.
