Quizzical Pursuit - The Architecture Puzzler
by Dave Guadagni
Answer for Last Week's Puzzler
In older buildings with thin-stone anchorage systems using carbon steel shims and anchors, the sealants occasionally fail and the steel can corrode.
Which statement correctly explains this?
a) The corroded steel is greater in volume than uncorroded steel, and joints inadequate to accommodate this volume increase sometimes fail.
b) The corroded steel is lesser in volume than uncorroded steel, and connections become loose due to the volume decrease and sometimes fail.
a). Corroding steel expands in volume and can put pressure on joints.
