Low Porosity, High Strength Concrete for Bridge Decks

IN TR O D U CTIO N -TH E PROBLEM A few years ago a problem that previously had been a modest highway maintenance concern suddenly became a major source of dif­ ficulty and expense to highway departments in many areas of the coun­ try; including Indiana. In brief, concrete bridge decks, some new, started to spall, then delaminate, then come apart in relatively large chunks. The problem was quick...

Evaluation of Autogenous Shrinkage in High-Performance Concrete

Recent tendencies in concrete technology have been towards to high- performance concrete with a low water-cement ratio. However, high performance concretes have some problems. One of the problems is early-age cracking due to autogenous shrinkage. This study presents the results of an experimental investigation carried out to evaluate the autogenous shrinkage of high-strength concrete. Accordi...

An Investigation on Transversely Prestressed Concrete Bridge Decks

This study is concerned with the development of design specifications for the use of transverse post-tensioning in concrete bridge decks. The ultimate goal behind this proposal is to improve the durability of concrete bridge superstructures. Experimental results from previous studies are used to validate the analytical models implemented in the development of the design specifications. It is fo...
