Fineness Modulus of Sand affects Compressive and flexural strength of Concrete. Sand, with higher FM, results in higher strength of concrete. It is evident by cost benefit ratio that overall concrete mix is becoming economical if we use sand with higher FM. The results indicate that with the increase in FM, workability gets affected considerably.

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
Dec 12, 2013· Pit Sand It serves as an excellent material for mortar or concrete work. Pit sand must be made free from clay and other organic materials before it can be used in mortar. A coating of oxide of iron over the sand grains should be removed. 6. RIVER SAND This sand is widely used for all purposes.

Assessing the quality of sand is a great idea to ensure the best construction. Sand is said to have more impact on the strength of the construction. The building may develop cracks or damages with use of improper quality of sand. Like any other material, there are certain features that determine the quality of sand. Good quality sand should not possess more than 4% of silt content.
Take a few minutes to learn about the three most commonly used sand types; Concrete Sand vs. Mason Sand vs. White Sand. Concrete Sand. Concrete sand is and aggregate sand usually composed of either gneiss, trap rock, limestone or granite. This specific type of sand is normally crushed at the quarry and then washed and screened for quality.
Feb 04, 2015· The recent findings have also indicated that varying the properties (flakiness) of coarser crushed sand fractions (0.125/2 mm and 2/4 mm) has much less relative impact on fresh concrete properties, and that the other fine particle (≤ 0.125 mm) characteristics, such as shape, surface texture and mineralogy, could have a similar effect as
Now-a-days good sand is not readily available, it is transported from a long distance. Those resources are also exhausting very rapidly. So it is a need of the time to find some substitute to natural river sand. The artificial sand produced by proper machines can be a better substitute to river sand.
