Modelling the cooling of concrete by piped water [PDF]
, 2009 Large concrete structures are usually made sequentially in a series of blocks. After each block is poured it must be left to cool and shrink for a period depending on its size, but typically for around 1 week, before the next block is poured.

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Recovery from anorexia nervosa involves psychological and social adjustments that extend beyond weight restoration. Online forums increasingly serve as spaces where recovery experiences are openly shared, including accounts of “extreme hunger” during refeeding—a phenomenon that has not been reported in the clinical literature.

Dynamic responses of concrete-faced rockfill dam due to different seismic motion input methods
International Journal of Distributed Sensor Networks, 2018 The concrete-faced rockfill dam valley foundation was considered as an open energy system and a reasonable non-uniform seismic motion input method was applied to the dynamic analysis of a concrete-faced rockfill dam based on the generalized plastic model.

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 ...

International Journal of Concrete Structures and Materials, 2020 This paper proposes an approach to assess and predict the seismic risk of existing concrete gravity dams (CGDs) considering the ageing effect. The combination of fragility function and cumulative absolute velocity (CAV) depending on two failure states ...

The use of FLAC for the seismic evaluation of a concrete gravity dam including dam-water-sediments-foundation rock interaction [PDF]
, 2017 Seismic safety of 65m-high Licodia Eubea gravity dam located in Southeastern Sicily (Italy) has been assessed by means of advanced dynamic analyses of the tallest cross-section of the dam. The analyses were performed with two-dimensional, plane strain,

Residual capability of alkali binding by hydrated pozzolanic cements in long-service concrete structures [PDF]
, 2018 An experimental procedure was developed and applied to cement pastes made with two different pozzolanic cements (CEM IV/B (P) and CEM IV/B (V)) in order to ascertain the existence of a residual capability of alkali binding by long-term hydrated ...
