Jul 01, 1989 The mixes of each series incorporated different percentages of very fine sand VFS as a replacement for fine aggregate. Results indicate that the water demand increases rapidly when the VFS replacement is more than 5 percent in natural sand concrete and more than 15 percent in crushed stone sand concrete.
Feb 12, 2015 The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical. Spherical particles decrease the percentage of voids
