| Abstract | ||
| This study deals with ultrasonic pulse velocity tests done on concrete to find out its compressive strength with different mix ratios, different water cement ratios and in different ages. The cubes used were 150x150x150mm and the batches were prepared using three mix ratios 1:1:2,1:1.5:3 and 1:2:4 respectively. For each batch three water cement ratios were used 0.4,0.5 and 0.6. The concrete cubes were tested at 3,7,14 and 28 days age in the compression machine. Before testing any cube, it was tested by an ultrasonic pulse tester to find out the velocity of the waves through concrete. Ansys software version11 was used to do the analytical work through so many runs to get the compression stresses in concrete and the displacement in z-direction (the direction of applying the load).A comparison was done between the experimental and analytical work through so many graphs in the study. The maximum percentage difference between the results of the two was between (6.4-7.8)% where the results of the Ansys were presented in two ways upper and lower bounds. The difference seems to be reasonable ,but a care must be taken in concrete assessment. | ||
