(
Qatar Univesrity Press
, 2020 , Conference Paper)
In an ever expanding world, our constant need to construct and to support a constantly
growing population is resulting in significant increase in construction waste. Rapid
expansion is a trend that can be seen throughout ...
High and Ultra-high Performance Concretes: A Solution to Reinforced Concrete Durability under Harsh Climate of Arabian Gulf
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Reinforced concrete (RC) infrastructure in the Arabian Gulf region deteriorates under
severe environmental conditions after only short service life. To overcome this problem,
it is imperative to employ high-quality concretes ...
