Anchored curtain wall being constructed to a height of 25 m and length of 150 m, completed to 15 m height
(Joao Monlevade, M.G., Brazil). The wall, of maximum thickness of 50 cm, is constructed in sections 1.5 m high
from the top down, with each section anchored to provide continuous support. Geologic Section is shown in
the inset. (From Hunt, R.E. and Costa Nunes, A.J. da,
