Effect of Cement Content on Concrete Performance" by

Dec 17,  · Of all the traditional concrete materials, portland cement has the greatest impact on mixture cost and the environment. Cement is in many ways the glue holding concrete together (Weiss, 1999), and as such, it plays a major role in fresh and hardened concrete properties. Without the proper range of cement in the mixture, low strength development or excessive shrinkage may occur leading

Types of Bridges Based on Span, Materials, Structures

Prestressed Concrete Bridge If concrete material is placed under compression before applying the loads, then it is called as prestressed concrete. To construct pre stressed concrete bridge, pre-stressed concrete blocks are arranged as deck slab with the help of girders. These blocks are suitable for shorter span to longer span bridges.

Investgiation into Improved Pavement Curing ... - Iowa

Concrete curing is closely related to cement hydration, microstructure development, and concrete performance. Application of a liquid membrane-forming curing compound is among the most widely used curing methods for concrete pavements and bridge decks. Curing compounds are economical, easy to apply, and maintenance free. However, limited research has been done to investigate the effectiveness

Bridge Basics - A Spotter's Guide to Bridge Design

Jun 03,  · While a typical arch bridge passes its load to bearings at its abutment; a tied arch resists spreading (drift) at its bearings by using the deck as a tie piece. Masonry bridges, constructed in stone and concrete, may have open or closed spandrels A closed spandrel is usually filled with rubble and faced with dressed stone or concrete.
