SV Technocrats India’s Concrete Cube Mould is used in construction and laboratory testing to cast concrete cubes for compressive strength testing. It ensures that concrete samples are uniform in size and shape, allowing for accurate strength measurements.

Specifications of Concrete Cube Mould

1. Standard Sizes:

o 150mm x 150mm x 150mm (most common for compressive strength testing)

o 100mm x 100mm x 100mm (used for smaller specimens or lower strength concrete)

o 50mm x 50mm x 50mm (used for specialized tests)

2. Material:

o Made of cast iron or mild steel for durability.

o Must be rigid, non-deformable, and resistant to rust.

3. Construction Features:

o Comes with bolted or welded joints to ensure proper shape.

o Smooth internal surfaces to prevent adhesion of concrete.

o Detachable base plate for easy removal of concrete cubes.

Usage of Concrete Cube Mould in Testing

1. Preparation

o Clean and oil the inner surfaces to prevent sticking.

o Assemble the mould on a level and firm surface.

2. Filling the Mould

o Fill in three equal layers with freshly mixed concrete.

o Compact each layer using a tamping rod (25 strokes per layer).

3. Curing

o After 24 hours, remove the cube from the mould.

o Submerge in water for 7 to 28 days for proper curing.

4. Compressive Strength Test

o The cured cube is placed in a Compression Testing Machine (CTM).

o Load is applied gradually until failure.

o The compressive strength is calculated as:

Compressive Strength=Maximum Load (N)Cross-Sectional Area (mm2)\text{Compressive Strength} = \frac{\text{Maximum Load (N)}}{\text{Cross-Sectional Area (mm}^2\text{)}}Compressive Strength=Cross-Sectional Area (mm2)Maximum Load (N)
