Consolidating concrete bridge structure applications

The uniformity of an SCC mixture reduces the permeability and enhances the overall durability of the concrete.This, in turn, enhances the lifespan of the SCC beyond that of conventional concrete (Corinaldesi 2005); thereby reducing the environmental footprint on a unit time basis.Fortunately, this also leads to a durable material because water, precipitation, and aggressive chemicals or ions are shed by the surface skin.Conventional concrete is placed using vibrators to fill the forms.Delivery methods include cast-in-place, precast, and tilt-up, and in every case, good appearance is essential.Achieving good surface characteristics requires thorough consolidation of the fresh concrete and thoroughly filled forms.SCC provides benefits beyond those of conventional concrete in all three aspects of sustainable development: economic, social, and environmental.The most important benefit of SCC is the increase in durability.

Some of its many sustainable properties and applications are further enhanced with the use of self-consolidating concrete (SCC).Self-consolidating concrete (SCC) is a big step forward in fool proofing that procedure.The construction industry has always longed for a high-performance concrete that can flow easily into tight and constricted spaces without requiring vibration.Flowability, passing ability, and stability are three of the most important characteristics of SCC.In 2001, ASTM started development of test methods that would assess these characteristics.
