Asphalt pavement performance depends on the base courses and sub-grate below it. We also provide aggregates and cement
Cement stabilized sand is widely available and cost-efficient; it utilizes less cement for a surface area while maintaining its durability. At Southern Crushed Concrete, our cement stabilized sand contains only lightweight pieces and is free of any organic damaging substance, as required by the City of Houston and Harris County.

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

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.

The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.

Proper calculation and relative proportioning of materials are important to produce a good quality concrete. Let’s see some simple techniques used by engineers to calculate cement, sand, coarse aggregate (gravel or Jalli) and water needed to produce different grades of concrete, like M5, M7.5, M10, M15 and M20.

Portland cement (PC), the most frequently used cementitious material for concrete worldwide, is associated with a large energy consumption and heavy carbon dioxide (CO 2) emissions due to the procedures involved in its production.About 4 billion tons of CO 2 are emitted by PC production every year, accounting for 5–7% of total anthropogenic CO 2 emissions , , , .

Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.

Crushed sand particle though shaped, does not have the spherical shape of natural sand. Hence the crushed sand will have greater water demand than that of natural sand resulting in slightly higher cement consumption. However, if crushed sand is properly graded with adequate fines the mix may have lower water demand when compared to poorly
