The production of manufactured sand also generates high percentages of microfines (namely stone dust), particles that pass the 75 μm sieve, ranging from 5% to 20% . Previous researches , , , , , have shown that good quality concrete can be made using manufactured sand with high amount of microfines. Generally the compressive strength, flexural

Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete. We are also using M-sand for current project.

Manufactured sand is defined as a purpose-made crushed fine aggregate produced from a suitable source material. Earlier users of manufactured sand have raised concerns about the effect of the shape and grading on water demand, the deleterious clays on both the water demand and early-age performance of hardened concrete and mineralogy on the

Manufactured sand provides an opportunity to control the particles'' mineral content, in contrast to natural sand, which often contains undesirable minerals and clays whose effects on concrete quality can be very harmful. Another reason for using manufactured sand is the growing shortage of natural sand.

Manufactured sands tend to be used in mixtures in areas where natural sand is not available or not cost effective to be hauled to the needed location. MFA tends to be more angular and flaky due to the crushing process. Highly angular particles tend to increase the paste content of concrete because additional lubrication is required for

First, manufactured sand is more uniform in structure compared with natural sand. It also has an advantage when it comes to concrete production, because manufactured sand is less needed in the concrete mix by a margin of 5 to 20% compared with natural sand to fill the voids volume between the particles. Even though the mechanical manufacturing
