The results reflected that workability slump increased with increasing aggregate size.The concrete made from the 9.5 mm 13.2 mm and 19.0 mm aggregate sizes had workability slumps of 10 mm

This may be due to the difference between the maximum aggregate size of silica sand 0.5mm and that of sand from the fluorite mine 0.3 mm since especially in cement-richconcrete.

For M20 30 liters of water per 50kg cement . Total amount of water required = 30 x 403.2/ 50 = 241.92 litre. 8.064 bags of cement required for 1 cu.m of M20 grade concrete. 630kg of Sand required for 1 cu.m of M20 grade concrete. 1260 kg of 20mm Aggregate is

On the other hand in smaller size aggregates the surface area is increased whichincreases w/c ratio and lower strength is achieved. In general for strength upto 200kg/cm 2 aggregates upto 40 mm may be used and for strength above 300 kg/cm 2 aggregate

The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the mostcommon size of aggregate used in construction is 20mm. A larger size 40mm is morecommon in mass concrete. Larger aggregate diameters reduce the quantity of cement and

Calculate the concrete quantity required in cubic meter and then multiply the quantitywith the cement sand and aggregate for 1 cubic meter of concrete. In your case Volume ofconcrete = 1.7 x 1.7 x 0.5 = 1.4 cu.m It looks like you are using m20 grade mix with

Size of column = 300 mm x 300 mm. Height of column = 3 meter. In this column we will usethe M20 grade of concrete which Ratio is 1:1.5:3 sum of ratio become = 5.5. where : 1is Cement 1.3 is Sand and 3 is aggregate. M20 grade of concrete compressive strength

Consider concrete with mix proportion of 1:1.5:3 where 1 is part of cement 1.5 is partof fine aggregates and 3 is part of coarse aggregates of maximum size of 20mm. The watercement ratio required for mixing of concrete is taken as 0.45. Assuming bulk densities of

2. The larger sizes will require less mixing water and hence for a given cement factorwill produce concrete of lower water-ratio than the smaller sizes. 3. The advantage ofsmall aggregate in the water-ratio strength relationship may or may not be sufficient to

The graded coarse aggregate is defined by its nominal size i.e. 40 mm 20 mm 16 mm12.5 mm etc. For example a graded aggregate of nominal size 12.5 mm means an aggregatemost of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to
