Lightweight Structural Concrete
When used in lightweight structural concrete mix, Buildex Haydite® offers many advantages. Most importantly, it helps mitigate Alkali-Silica Reaction (ASR).
ASR is of great concern to many Departments of Transportation because aggregates containing certain silica constituents can, under certain conditions, react with the alkali hydroxide developed during hydration of cement. This reaction may cause expansion and cracking in the cement – which shortens the service lives of pavements and structures.
The use of Haydite® lightweight aggregate in concrete saves materials, energy, labor, and construction and transportation costs because it improves the performance and service life of concrete.
