Effect of Sand Fines and Water/Cement Ratio on Concrete ...

2019-10-29  concrete consisting sand with fines content of 2%, 4%, 6%, 8%, 10% and 12% with three constant water/cement ratios of 0.55, 0.60 and 0.70 were prepared for the study. The amounts of coarse aggregate used were kept constant for all batches. The concrete were mixed using 1m3 drum concrete mixer. Workability test: Slump measurement was taken

Concrete Aggregates - sand, cement, coarse, fine,

2011-11-15  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.

Aggregates Difference Between Coarse And Fine

2021-5-8  With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.

What is the size of coarse sand, medium sand and fine

2018-5-4  The thickness of sand is divided into 4 levels on the basis of fineness modulus. Coarse sand: its fineness modulus is 3.7-3.1, the average particle size is over 0.5 mm. Medium sand: its fineness modulus is 3.0—2.3, the average particle size is 0.5—0.35 mm. Fine sand: its fineness modulus is 2.2—1.6, the average particle size is 0.35—0.25 mm.

Concrete Aggregates: Why We Grudgingly Love ASTM

2021-4-5  Concrete is something that we take for granted. But, without cement and concrete modern life would not be possible. Even in “modern” 6500 BCE, people living in what we now call Syria knew it was an essential material. The Romans used concrete widely in 600 BCE and by 200 BCE, they used it in almost all their construction.

PARTIAL REPLACEMENT OF COARSE AGGREGATES IN

2017-10-30  In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of Portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates which hardens over time. Mostly used concrete is the lime-based concrete which is the Portland cement concrete.

However there is a limit as too much coarse aggregate make more difficult to compact the concrete and result in lower density. Too rich the cement content also will reduce the density.
