๐Concrete Mix for Ground Floor Slab โ Details
For a 1 mยณ concrete floor slab, the infographic shows a nominal 1:2:3 mix ratio:
Cement: 1 bag of Portland cement (OPC), approximately 50 kg
Fine aggregate: 2 buckets of clean sand
Coarse aggregate: 3 buckets of well-graded gravel
Water: approximately 22โ27.5 litres, depending on the required workability and moisture content of the aggregates
Typical bucket volume: about 0.035 mยณ (35 litres)
Floor Slab Construction Steps
1. Prepare the formwork โ ensure it is properly aligned, level, rigid, and adequately supported.
2. Place reinforcement โ install the steel reinforcement/mesh according to the structural drawings, maintaining the required concrete cover.
3. Pour the concrete โ place concrete continuously where possible to avoid weak construction joints.
4. Spread and level โ use a screed to achieve the required slab level and thickness.
5. Compact properly โ remove entrapped air using suitable vibration/compaction methods.
6. Finish the surface โ achieve the specified finish without adding excess water.
7. Cure the concrete โ keep the concrete adequately moist and protected, with 7 days as a minimum reference where appropriate; follow the project specification and applicable code.
Important Note
The 1:2:3 ratio is a nominal volumetric mix, not a substitute for structural mix design. For structural floor slabs, the required concrete grade, slab thickness, reinforcement, water-cement ratio, aggregate grading, exposure conditions, and curing requirements should be determined from the structural design and applicable local standards.
Good materials + correct proportioning + proper placement + compaction + curing = stronger and more durable concrete.
