Spalling
 Q:
I heard that there is an admixture for concrete to reduce the effects
of salt-induced spalling and general deterioration of concrete.
Is there such an admixture?
A: While there are a
number of chemical admixtures and supplementary cementitious materials
that can improve the quality of concrete, there is no substitute
for quality concrete when the issue is spalling or scaling. The
most important factors in achieving durable exterior concrete surfaces
are appropriate cement content, air-entraining admixture (to produce
the proper air content for the aggregate size), and proper placement,
consolidation, finishing and curing. For more information read:
