· Best Concrete. In the production of concrete is usually used in the mortar. Sand is crushed into small pieces then it takes into the filtered to confirmation that no massive rock particle is included. After that mixing of cement and water, then that fills the air spaces between the coarse aggregate. Sands can also be used in pipe sand or walkways as a levelling medium and pools, patios

Compared to conventional concrete (made using of river sand), the concrete with 50% crushed sand reduces its slump value, has a lower porosity, and has a compressive strength value of MPa at 28 days, which is very similar to that of conventional concrete ( MPa). Moreover, it was found that the strength of the concrete increased by % and %, respectively, for concrete

· The fines content is usually high in crushed sand which can adversely affect concrete properties. The influence of fines in crushed sand on physical and mechanical properties of concrete has been widely investigated. The results proved that up to 15% of fines content in crushed sand could be used without adversely affecting concrete strength. However, little work has been done so far on

Concrete Sand from Southern Crushed Concrete is a fine aggregate that is used in the production of concrete or mortar. Concrete sand is crushed in a quarry then filtered to ensure no large rock fragments are left behind. When mixed with cement and water, a grout is formed that fills the voids between the coarse aggregate. Though typically used in the creation of cement, concrete sand can

Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are wellrounded and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste is required to fill these voids. Wellshaped natural sands are ideal for workability of mixtures. Natural sand does not require more water to
