Jan 1, 1994 . In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. . For the high cement contents used in the production of high-strength concrete, coarse sand with an FM around 3.0 produces concrete with the best.
mixes As the aggregate for producing concretes, natural sand was used with maximum particle size. 4.76 mm, a particle density of 2520 kg/m3 and Modulus of Fineness of 3.47. The coarse aggregate was a 12.7 mm crushed granitic stone with a particle density of 2698 kg/m3 .The amber waste glass was ground in a jaw.

Since sand bulks in volume when it is damp, the mix ratio table (below) is based on the use of damp bulked sand. If you are measuring dry sand, reduce the quantity of each batch by 20–25 percent. You will also need to add more water to compensate for the lack of water in the sand. The recommended ratios are based on.

Abstract: - Volume of concrete consumed by the construction industry is very large. In India, conventional concrete contains natural sand obtained from riverbeds as fine aggregates. In recent times with a boost in construction activities, there is a significant increase in the consumption of concrete causing the dwindling of.

In today‟s world the use of natural aggregate has increased extensively. We live our lives dependent on an infrastructure created out of concrete. Concrete is a composite material of which 60-75% by volume is aggregates. Out of this volume, 30-40% is constituted by fine aggregates. Although potential sources of fine.

The sand used was confirming to zone 3. Fineness modulus and specific gravity of the sand were found to be 6.59 and 2.6 respectively.
gravity and bulk density have to be assessed to design a dense fine aggregate mix with optimum cement content and reduced mixing water. The sand should be tested properly as it is the ingredient of the concrete that is to be partially replaced in this project. For Fine aggregate we are conducting test like. Fineness Modulus.
Apr 15, 2013 . Locally available river sand with fineness modulus of 2.72 and specific gravity of 2.64 has been used. Crushed granite coarse aggregates of size ranging from 7 mm to 20 mm have been used at the saturated surface dry condition. A combination of sodium silicate (Na2SiO3) solution and sodium hydroxide.
