structures are in structural concrete. The functional demands of such high rise structures include the use of durable materials. High Strength Concrete‚ Self–compacting Concrete are gaining widespread acceptance. Apart from the basic structural materials‚ modern projects require a variety of secondary materials for a variety of purposes such as construction chemicals‚ waterproofing materials‚ durability aids etc. The paper highlights some of the recent developments.
