Bulking of Sand – If the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. If we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3 (30% more). The reason for that is the moisture content present in the sand makes it a little bulkier.
Coarse sand has larger particles than fine sand . That is the main difference . Coarse might have a minimum mesh gauge size of say 400 micrometres and a maximum of 3mm where the fine sand might have a maximum mesh gauge size of 300 micrometres . D...
The sand required for mortar and concrete is quite different. Mortar has to provide an even transfer of compressive loads between the bricks by conforming closely to the dips and bumps on the bricks, so the sand needs to be quite fine. In Australi...
Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume
11-08-2018· Sand is the finest aggregate. It comes in different gradations: sharp sand, builder’s sand, and kiln-dried silver sand, which vary from coarsest to finest, respectively. Finer sands are a good aggregate for mortars and grouts. Coarser sands are also a popular aggregate for concrete mixes.
25-09-1970· therefore, desirable to choose a suitable ratio of fine to coarse aggregate proportions of the concrete to allow some fluctuations in the grading zone of the Ane aggregate. 0.31 The four grading zones indicated in this standard are meant to cover the use of the natural sands available in the country.

Coarse and Fine Sand. Coarse sand is washed sand which has small to medium granules. Our coarse sand is commonly used for mixing concrete and leveling paver stones. Fine sand is typically used for concrete mixes. It is the ideal sand to use when filling sand bags and sand boxes.

21-11-2017· The sand which is passing through the 7.62 mm sieve is called gravelly sand. This type of Sand is used in making concrete. Coarse Sand :-The sand which is passing through the 3.175 mm sieve is called coarse sand. This size of sand is mostly used for masonry works. Pit sand is mostly coarse in nature. Fine Sand:-
The Aggregates(fine + coarse) generally occupy 60% to 75% of the concrete volume or 70% to 85% by mass and strongly influence the concrete’s freshly mixed and hardened properties, mixture proportions, and economy. All Aggregates pass IS 4.75 mm sieve is classified as fine Aggregates.

Abstract-Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate).
The Aggregates(fine + coarse) generally occupy 60% to 75% of the concrete volume or 70% to 85% by mass and strongly influence the concrete’s freshly mixed and hardened properties, mixture proportions, and economy. All Aggregates pass IS 4.75 mm sieve is classified as fine Aggregates.
There are different methods for testing of sand quality at construction site for concrete construction. Quality of sand is as much of importance as other materials for concrete.
