Tests in progress in NBRRI labs and notice how the concrete simply weakly split. If you compute from the crushing load, it is actually 2.3MPa, which is truly criminal. With the spade of the collapse of bridges also, is there not the need for some sort of emergency.
The rods have also been tested and they are better but there were no clear failures of tensile reinforcement in the rubble. The sizes of members have also been studied and some trial design will give confirmations. Ultimately, there is also need for radicality in professional ruling on minimal foundation depths correlated to common spans based on the height of the structure, if it is not piled, and maybe those who have money can immediately set up premixed concrete businesses to save us in Nigeria.
