Concrete Aggregates - sand, cement, coarse, fine, gravel ...

For a rich mortar—that is, one relatively rich in cement—a coarse sand is best. For a lean mortar, a small admixture of fine sand with the coarse is beneficial. If very fine sand is the only kind available, the mixture must be excessively rich in cement, and a smaller quantity of the sand in proportion to the gravel or stone may be used. To secure great density and practical water-tightness of concrete, a larger

Effect of Fineness of Sand on the Cost and Properties of ...

Sand has been sorted in three categories i.e. Fine, Medium, and Coarse. These were mixed with coarse aggregate in different proportions so as to keep the combined Fineness Modulus (all-inaggregate) more or less the same. Various proportions of such aggregate are mixed in preparing M 30 grade of Concrete

Sieve analysis of fine and coarse aggregate for concrete ...

19/04/2020  Gradation is usually specified for each engineering application it is used for. For example, foundations might only call for coarse aggregates, and therefore an open gradation is needed. Gradation is primarily a concern in pavement mix design. Concrete could call for both coarse and fine particles and a dense graded aggregate would be needed. Asphalt design also calls for a dense graded aggregate. Gradation

How To Calculate Cement, Sand And Coarse Aggregate For ...

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.

30/04/2020  The ratio of fine aggregate to coarse aggregate to be used in concrete is 1:2, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete.

Aggregates are frequently applied as the raw material in concrete mixtures. Sand, gravel or crushed stone are considered as the most vital materials in the concrete mix and cover roughly 60% to 75% of the total volume of the concrete. The main objective of aggregate is to unite the concrete. There are two types of aggregates like fine and coarse aggregates. Both can be applied to develop ...

Importance of Gravel and Sand for Concrete Hunker

Smaller gravel particles equals a "fine" grade of concrete. Use the fine aggregate for concrete slabs or other smooth surfaces. A "coarse" aggregate means using larger pieces of gravel. Coarse concrete is helpful for sturdier projects. Concrete with a coarse aggregate doesn't produce a smooth look or feel but is stronger than a finer grade.
