Impact of Vibration on Curing and Strength of Concrete

14 Aug 2017 31 Aug 2017

3 (931 )

Scope Research Need: During its setting process, fresh concrete transforms from a flowable state, via a plastic state, to a final solid state that includes a large number of crystalline domains formed by ionically and covalently bonded atoms. Early-age concrete thus is vulnerable to vibration damages if the formations of the chemical bonds and crystalline domains are negatively affected, leading to reduced early and ultimate ...
