Abstract:
Q. According to Provision 1.6.4.2 of ACI 301-16,1 a
rebound hammer cannot be used for in-place
strength testing. Does ACI recommend any other
nondestructive testing (NDT) method for in-place strength
evaluation?
Q. My company will be placing a concrete slab
foundation designed to directly support the base
of a steel tank. Does ACI have any documents that
discuss tolerances for elevation of such slabs after placement?
