06/10/2020 The cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. First, density is the ratio of mass to volume. So it can be indicated in terms of kg / m 3 , which is 1440kg / m 3 for cement .
The cement mixed with fine aggregate to have mortar for plaster and masonry, and with sand and coarse aggregate to give concrete. As I said, earlier density is the material’s mass per unit volume. Since we measure mass in kg or lb and volume in litre or cubic meter or cubic feet, hence density is stated in Kg/m 3 or lb/ft 3 .
Cement is rarely used on its own, but to strong bond sand and gravel. Density of cement is 1440kg/m3 or it is measured in other unit- their density is 1.440 in g/cm3, 90 in lb/ft3 and 14.40 in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3 is density of cement. Density of cement in kg/m3. density of ...

Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete
The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). [2] Relative Density of Aggregate [1] The relative density (specific gravity) of an aggregate ...
As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs. per cubic foot. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used. Lightweight concrete has a density of 115 lbs. per square foot.

Density of Cement = 1440 kg/cum (Approx) Volume of 1 Kg of Cement = 1/1440 = 0.000694 cum. Volume of 01 bag (50 kg) of cement = 50 X 0.000694 = 0.035 cubic meter (cum) Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) Volume of Sand required would be = 0.035*2 = 0.07 cubic meter (cum)

Aggregates comprise the greatest volume percentage in portland-cement concrete, mortar, or asphaltic concrete. In a portland cement concrete mix, the coarse and fine aggregates occupy about 60 to 75% of the total mix volume. For asphaltic concrete, the aggregates represent 75 to 85% of the mix volume. Consequentially, the aggregates are not inert filler materials. The individual aggregate ...
Dry aggregate contains 33 to 34% air voids, whereas sand contains 20% air voids and cement contains very fine particles hence it contains negligible are voids so we can ignore it. Now add the air voids of sand and aggregate that are 20% +34% = 54% so this is the reason we have to add 54% for wet to dry volume of materials.

24/08/2020 The void content of aggregates is important in determining the requirement of fine aggregate and cement for a workable concrete, as amount of cement-sand mortar required depends on void contents of aggregate that need to be filled with fine aggregate and cement. Significance and use. Determination of bulk density and void content of aggregate are necessary for use for many

The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate. I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete.
The bulk density values determined based on this test can be used for many methods of selecting proportions for concrete mixtures. Added to that, the evaluation of the percentage of voids between particles in fine, coarse, or mixed aggregates is dependent on the bulk density. It is worth knowing that, aggregates in stockpiles contain absorbed and surface moisture (the latter affecting bulking ...
Specific gravities of concrete materials are as follows: Cement = 3.15. Sand = 2.6. Coarse aggregates = 2.6. The percentage of entrained air assumed is 2%. The mix proportion of 1:1.5:3 by dry volume of materials can be expressed in terms of masses as: Cement = 1 x 1500 = 1500. Sand = 1.5 x 1700 = 2550. Coarse aggregate = 3 x 1650 = 4950.
