Typically used as the compound for joining masonry, stone or ceramic units together, mortar is made by combining cement, lime and sand. Mortar typically has a higher water to cement ratio when compared with concrete which allows greater workability and is required to form mortars bonding properties.
Concrete is a mixture of cement, sand (fine aggregate), small stone or gravel (coarse aggregate) and water. It has many applications, from fence posts to motorway bases and, because of this, there are many different concrete mix ratios that the constituents can be mixed to with each resulting in a different strength of concrete.
What is 1.54 constant in concrete calculation? 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
Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength of concrete. The volumetric mix ratio of M20 concrete is 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume will be taken for preparing concrete. However, above concrete mix ratios may not be accurately followed in
According to IS 10262 (2009), Assuming Water-Cement Ratio for the Concrete as 0.45 Required Amount of Water = W/C Ratio X Cement Volume Therefore, Water = 0.45 X 0.3636 m 3 = 0.16362 m 3 Unit Weight of Water = 1000 litres/m 3

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.
In other words, a concrete mix ratio allows you to reliably add the right amounts of powdered cement, aggregate, and sand when mixing the same type of concrete. A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio.

2. Sand should be clean, well graded, free from excessive clay, organic material and fine silts. 3. The often-used engineering term “water-cement ratio” is a ratio of weights. For example, a typical “water-cement” ration of 0.5 equates to mix ‘mix-by-volume’ ratio of about 0.66. 4.
That means, Cement content for 100 unit of 1:1.5:3 ratio concrete is 28% (unit will be as concrete unit), Sand is 42% and Stone chips is 84%. Now lets calculate the water content of concrete. Suppose, water-cement ratio for concrete is specified 0.45. That means, water/cement = 0.45, or W/C = 0.45.
Quantities of materials for concrete such as cement, sand and aggregates for production of required quantity of concrete of given mix proportions such as 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25) can be calculated by absolute volume method.
