The desired concrete mixes for different construction works

 

 

This construction article will focus on the ratios and quantities of desired concrete mixes for different types of construction projects.

 

Concrete is the most vital construction element for developing the buildings, roads and other monuments. Concrete is a combination of cement, water, sand and broken stones (jelly) in a specific proportion that refers to a feasible mass primarily and gets solidified over a period of time.

 

The concrete is generally known with its strength that is the compressive stress necessary to produce a 150mm x 150mm x 150mm cube crack. It is titled as M10, M20, M25 and so on. M20 concrete denotes that this concrete has the ability to bear a pressure of 20 Mega Pascals (applies to 200 kg force over an area of 1 cm x 1 cm).

 

If the produced concrete contains some definite properties (like strength, for specific type of work etc.,), it is named concrete mix proportioning. The strength of concrete is affected by the quality, strength and other properties of the ingredients in concrete like sand, jelly or crushed stones and cement.

NOTES: If grading for both fine and coarse aggregates is done in a unsatisfactory way, the following general rules concerning proper proportioning of these should be followed :-

The provides the following benefits :-

 

1. For utmost size of coarse aggregates as 40mm and over, the quantities of sand must be half as much as coarse aggregates.
2. For utmost size of coarse aggregates as 20mm and over, the quantities of sand must be two-thirds as much as coarse aggregates.
3. For utmost size of coarse aggregates as 16mm, sand and coarse aggregates must be in identical portions.
