APPLICATIONS OF DIFFERENT ORDINARY CONCRETE MIXES
DIFFERENT MIXES OF ORDINARY CONCRETE AND THEIR APPLICATIONS
There are different grades of concrete among them there is 3 category's they are
- Ordinary Concrete mixes.
- Standard Concrete mixes.
- High Strength Concrete mixes.
SL | Type of works | Grade | Mix of Ordinary Concrete | Maximum size of coarse aggregate | Water in Litres per Bag of cement | Consistency |
1 | Concrete deposited under water, RCC water retaining structures, well kerbs, platforms, important RC structures, piles, arches etc. | M-20 | 1:1 ½ :3 | 12mm to 20mm | 30 | Medium |
2 | Beams, slabs, columns, retaining walls, roads, pavements, drive ways, bunkers, foundation of bridges, bed blocks, drain linings etc. | M-15 | 1:2:4 | 12mm to 40mm | 32 to 36 | Stiff to medium |
3 | Mass concrete work for retaining walls, compound walls, part of flooring of water tanks resting on ground, machine bases, foundation of bridges etc. | M-10 | 1:3:6 | 12mm to 40mm | 37 to 40 | Stiff to medium |
4 | Foundations under column footings, wall foundations, mass concrete for heavy wall, Plain Concrete, Hearting of abutments & pipes, retaining walls with stone facing in hilly area etc | M-7.5 | 1:4:8 | 20mm to 40mm | 45 | Medium |
5 | Foundations of ordinary buildings encasing pipes etc / of light structures | M-5 | 1:5:10 | 20mm to 40mm | 60 | Medium |
The standard concrete mixes and the High strength concrete mixes are used based on the strength aspects.
