Experimental Study of the Creep Effect on the Mechanical Properties of Concrete
Advances in Civil Engineering, 2019 Available researches regarding the effect of a sustained load on concrete are limited and sometimes contradictory. In the specific context of prestressed concrete and more generally for all other concrete structures, the effect of creep on the residual ...

New insights into epileptic spasm generation and treatment from the TTX animal model
Epilepsia Open, EarlyView.Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

, 2018 Uniaxial compressive creep of a 90+% Al(,2)O(,3) and 50+% Al(,2)O(,3) refractory concrete was investigated. The creep behavior was evaluated as a function of aggregate packing, cement composition, and time at temperatures up to 2200(DEGREES)F and stresses up to 2500 psi;Refractory concrete crept more when heated the first time than on subsequent ...

Energy Science &Engineering, EarlyView.Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...
