These NPS Publications help historic building owners recognize and resolve common problems prior to work. Since its introduction in 1983 the Delcrete ® Elastomeric Concrete/ Strip Seal Expansion Joint System has been utilized on hundreds of bridges worldwide as an alternative to more labor intensive cast- in- place expansion joint rehabilitation solutions. Cast- in- Place Concrete.

Many different types of structures frames , components of structures can be built using reinforced concrete including slabs, beams, columns, walls, foundations more. The research on the application of microcapsules into concrete to obtain a self- healing capacity was started recently. The strength stiffness of the composite girder can be calculated by transforming the concrete portion into steel using Modular Ratio n = E s / E c; E c = w c 3/ 2 ( 33) ( f’ c) 1/ 2. Reinforced concrete can be classified as precast or cast- in- place concrete.
