Two Methods of Compressive Strength Testing Cube Test The cube test is the most common method for determining the compressive strength of concrete in the UK. This test involves casting concrete into cube moulds, curing them under controlled conditions, and then crushing them in a compression test...
Cube samples measuring 150 × 150 mm2 were used for this test, which was conducted at both 28 and 56 days of age. Preparing SCC disc shape specimens and testing fracture toughness As previously mentioned, Aliha et al. developed ENDB samples to calculate the critical stress intensity ...

The existing 'strain column' method for preventing non-uniform straining by testing machines is compared to a proposed new procedure in which the amount of strain non-uniformity that occurs in the course of normal cube testing is measured, then the effect it has had on the cube's strength ...
The variability of results is also assessed in relation to the above factors, and an estimate made of the accuracy of predicted actual cube strength that is likely to be achieved from testing cores of this size. (TRRL) 展开 关键词:

Once the required consistency was achieved, the fresh concrete was poured into 150 mm × 150 mm × 150 mm cube moulds for testing. These samples were allowed to cure under controlled conditions, with testing performed at 7, 28, and 90 days. 2.2.2 Preparation of beam samples Beam...
3. Test results and discussion 3.1. Summary of experimental results Bond strength (τb,max) was calculated by dividing the load (Fult) recorded with the load cell of the testing machine by the shear surface (Eq. (1)). Uniform bond stress distribution was assumed along the bond length (lb...
To study the flexural strength of the prepared concrete mixtures, rectangular cube specimens with the dimensions of 100 mm × 100 mm × 400 mm were prepared and then a three-point flexural test was done according to BS EN 12390-5 standard35. The condition of flexural testing was ...
