Frank Greening's paper on "The Pulverization of Concrete in WTC 1 During the Collapse Events of 9-11":
http://www.911myths.com/WTCONC1.pdf

From 6.3 The Pulverization of Concrete by Explosive Blast:

These papers show that explosive blast is not a particularly effective means of
pulverizing concrete especially if the explosive charges are not in direct contact with the
target. Thus, for example, spherical charges of 10 kg TNT-equivalent placed 0.5 m above
a 3 m ? 1.5 m area, 15 centimeter thick concrete slab produce a post-detonation crushed
zone only about 30 cm in diameter. It is for this reason that mining and quarrying
operations generally use explosive charges placed into drilled boreholes to achieve
maximum fragmentation.
