The most common concrete mixes ratios by weight are expressed as parts, where the weight of each component is represented in relation to the weight of cement, which is assigned a value of 1. For example, a common mix ratio for general-purpose concrete is 1:2:3, which means one part cement, two parts sand, and three parts aggregate.
The general expression for the proportions of cement, sand and coarse aggregate is 1 : n : 2n by volume. 1 : 1 : 2 and 1 : 1.2 : 2.4 for very high strength. 1 : 1.5 : 3 and 1 : 2 : 4 for normal works. 1 : 3 : 6 and 1 : 4 : 8 for foundations and mass concrete works. ... lesser the water-cement ratio in a workable mix greater will be the strength ...
Concrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. These mix ratios are decided based on type of construction and mix designs. However, building codes provides nominal and standard concrete mix ratios for various construction works based on experience and testing. These types of concrete ...

The ratio of sand to Portland Cement-Lime Mix should be between 1:214 to 1:312 cubic feet. This will produce a mortar that meets the property specification requirements of ASTM C270 (Table 1). What is concrete made of? Concrete consists of cement, air, water, sand, and gravel. It usually follows the 10-20-30-40 Rule for proportions.
Suppose 1 kg of mortar is to be prepared. Cement:sand ratio is 1:3 by volume and suppose w/c ratio is 0.4; Assume bulk densities of water as 1 g/c, cement as 1.4 g/cc and fine aggregate as 1.6 g/cc. So, mass ratio of cement: sand is 1 part * 1.4 : 3 part * 1.6 . This means of 1 kg mortar, 0.4 part is water, 1 part is cement and 3.43 parts are sand.

To make 1 cubic metre of 15 Mpa concrete you will need to mix 5 1/2 bags of cement with 0,75 cubic metres of sand and 0,75 cubic metres of stone.
On this page, you can calculate material consumption viz., cement, sand, stone gravel for the following concrete mix ratios - 1:1.5:3, 1:2:4, 1:3:6, 1:4:8, 1:5:10. Once, the quantities are determined, it is easy to estimate the cost of a concrete block, driveway, patio, yard or any other structure with the price prevailing in your area.
The standard ratio for average mortar mix is 3:1 or 4:1 for bricklaying. If you are using a pointing mix, then you should have a ratio of 1:4 or 1:5 mortar to sand. As for concrete, it depends on the strength you need it to be at. Usually, it is good practice to mix concrete at …
In a mixing container, add no more than 1 part cement to 2 parts sand. For some applications, you may add up to a 1:8 ratio of cement to sand. More cement means more strength and stickiness but less workability. Ratios …
Mortar Cement Mix This mortar mix is the next generation masonry cement. The mixture of mortar cement is similar to masonry cement. The only difference is that the mix is prepared and optimized to reduce the air content in it. Masonry cements are prepacked and they are mixed with water and sand at the construction site.
