Well, this is the fundamentals things of Building Estimation that every civil Engineer should go through it. Concrete comprises cement, fine aggregates, coarse aggregates and water in mix proportion.you can also Learn how to calculate the quantities of ingredients in slab
Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.
How to Calculate Cement, Sand and Coarse Aggregate Quantity in Concrete? We have already discussed Nominal Mix of Concrete and Mix Proportions .
In the step 3 of “How To Calculate Quantities Of Cement, Sand And Aggregate For Nominal Concrete Mix (1:2:4)” you have calculated that: 01 cum of concrete will require Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags Sand required = 115/0.167 = 688 Kgs or 14.98 cft Aggregate required = 209/0.167 = 1251 kgs or 29.96 cft
• Important for coarse and crushed fine aggregate these require an increase in mixing water and may affect the strength of the concrete, if cement water ratio is not maintained. • If water content of the concrete mixture is not kept constant, the compressive strength, workability, and other properties will vary from batch to batch.
Coarse and fine aggregate will generally have absorption levels (moisture contents at SSD) in the range of 0.2% to 4% and 0.2% to 2%, respectively. Free-water contents will usually range from 0.5% to 2% for coarse aggregate and 2% to 6% for fine aggregate.
Calculating sand–aggregate ratio according to,and at the same time referring table according to water–cement ratio and the maximum grain size of coarse aggregate, one can get the homologous sand–aggregate ratio. Comparing them with the actual sand–aggregate ratio (as in Fig. 5, the two right lines are the upper limit and lower limit of value obtained by referring table, respectively
Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3). Here, for coarse aggregates, the standard test method has been explained in ASTM C 127(AASHTO) and for fine aggregates

This study was conducted to determine the effect of concrete strength using coarse aggregate 10mm, 20mm and fine aggregate (sand mining) 3mm, randomly purchased from suppliers. These samples were test using with the mixing ratio of 1: 2: 4 and water cement ratio is set 0.5. Cement used was Ordinary Portland Cement. Each aggregate size are casted into three concrete sample of 600mm x 100mm x
12/08/2019· From the Fig. 8, Fig. 9, it is observed that due to 100% replacement of fine aggregate with copper slag excess of water gets stagnant in concrete and leaves more amounts of voids and capillary channels. The formation of this voids and capillary channels effects interlocking bonding between cement and aggregates which results in the loss of
standard weight ratio of sand aggregate in m10 concrete. 7297 USD. Proportion a concrete mix Fine Aggregate sand. Cement. In this case, the ratio implies 1 part (by weight) of cement to 2 parts coarse aggregate to 2 parts fine aggregat...
For example, the ratio 1:2:4 refers to a mix which consists of 1 cubic foot of cement, 2 cubic feet of sand and 4 cubic feet of gravel. Cement and water are the two chemically active elements in concrete and when combined, form a paste or glue which coats and surrounds the particles of aggregate and upon hardening binds the entire mass together.

how you calculate the qty. of cement ,sand,aggregate from proportion 1:2:4 M15.. Answer / sindhumani To find the individual ratio of materials we have to use one
11/08/2018·  COARSE AGGREGATE. Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water
Concrete Information Wiki. Water absorption limits on aggregates. Limits on aggregate water absorption are rare though they may be useful to link to an undesirable concrete property, such as freeze-thaw susceptibility, as water absorption is easily determined.
(Note 1: For every ±0.05 increase or decrease change in w/c, the coarse aggregate proportion is to be changed by 0.01.If the w/c is less than 0.5, volume of coarse aggregate is required to be increased to reduce the fine aggregate content in mix. If water cement ratio is more than 0.5, volume of coarse aggregate is to be reduced to increase the fine aggregate content.
