Concrete Mix and Strength Guide
Concrete Strength Usage
- M10 (1:3:6): Non-load bearing floors, lean concrete, base for paving blocks.
- M15 (1:2:4): Most commonly used for residential slabs and floor screeds.
- M20 (1:1.5:3): Where moderate strength is required (e.g., water tanks, retaining walls).
- M25 (1:1:2): High-strength structural elements like columns, beams, and highly loaded structures.
What is Slump?
Slump measures the workability (consistency/fluidity) of concrete. It is the distance (in mm) the concrete cone slumps after the mold is removed.
- 80mm or less: Standard reinforced concrete for foundations and slabs.
- 120mm or more: Used when concrete is pumped (Pumping Car) to prevent blockages.
- 150mm or more: For narrow walls or structures requiring very high fluidity.
DIY Screed/Pouring Tips
A mixture of only cement and sand is called 'Mortar'. 'Concrete' includes gravel (aggregate) which gives it strength. When paving a yard yourself, lay down wire mesh before pouring to prevent cracking. Do not add all the water at once; monitor the consistency and add water gradually. Too much water reduces the final strength.
