Concrete Hydrodemolition | Water Jetting Applications
Hydrodemolition, also known as water blasting, water jetting and hydroblasting, is a concrete removal process that works by using ultra high pressure water blasting to cut away damaged or otherwise unsound concrete. The elegance of water blasting concrete using hydrodemolition equipment instead of the older mechanical tools, like the jackhammer ...

State of art of review on bamboo reinforced concrete
S.Y. Kute, M.R. Wakchaure (2013) [5] studied about the reduction of water absorption by bamboo significantly without affecting bond strength in bamboo reinforced concrete at low cost because the main disadvantage of Bamboo in concrete is water absorption. During curing, bamboo has absorbed water and it starts expansion, which results in radial cracking in …
