To determine the modulus of rupture of concrete and it's relation to cube crushing strength (Min ratio 1:2:4 & water cement ratio =0.60)

 

OBJECT: To determine the modulus of rupture of concrete and it's relation to cube crushing strength (Min ratio 1:2:4 & water cement ratio =0.60)

APPARATUS: Cube mould (15cm x 15cm x 15cm). Beam mould (10cm x 10cm x 50cm). Trowel, Tamping rod, Plate vibrator, glass jar 1000cc.

PROCEDURE:

1. Mix concrete constituents thoroughly first dry then with water.

2. Fill cube & beam moulds in 3 layers and compact each layer by tamping rod gluing 25 blows. Now compact by plate vibrator.

3. Mark identification mark after finishing.
