In threu years we have accuwulated a large tacklog of failure conditicns wnen entrained gases occur within concretes and costings.

Failures in the integrity of the exposed surfaces of concretes cause essive clean-up proolems at the very least.

I mule like to discuss this situation further with ycu es;:ccially in view of the 'Jaterfcrd prof, acts going up outsica of =atru ?.cw Orleans.

If you nave any cuestions concerning the sinulation, we can sup;ly detailed materials and engineering infor=stica.
