Casting of Cement Concrete Cubes & it's Procedure...

The following equipment's are needed for the preparation of concrete cubes:
1. Mould for making test cube (150mm*150mm*150mm)
2. Temping Rod (16mm Diameter & 600mm Length)
3. Scoop
4. Steel float or trowel
5. Cleaning rags
6. Curing tank
7. Permanent Marker

Number of cubes:
6 no. of Cubes of 150 x 150 x 150 mm size shall be cast, 3 for 7-days testing and 3 for 28-days testing. A sample consists of 3 cube specimens and their average compressive strength represents the test result of that sample.

Casting of Cubes:
The cube mould plates should be removed, properly cleaned assembled and all the bolts should be fully tight. A thin layer of oil then shall be applied on all the faces of the mould. It is important that cube side faces must be parallel.
The concrete sample shall be filled into the cube moulds in 3 layers, each layer approximately 50mm deep.
Each layer of the concrete filled in the mould shall be compacted by not less than 35 strokes by tamping bar.

Curing:
The casted cubes shall be stored at a temperature 22'C to 33'C for 24 hours.

Marking:
Immediately after initial curing of the cubes they should be marked clearly for testing.
