WebAbstract. A previous material model for the increase of creep of concrete caused by simultaneous drying is extended to describe the effect of both drying and wetting, as … WebCreep (Dimensional stability) Creep is defined as the gradual increase in strain with time for a constant applied stress after accounting for other time-dependent deformations not associated with stress, namely, shrinkage or swelling and thermal strain. Hence, creep is reckoned from the elastic strain at loading, which depends upon the rate of ...
WebFeb 1, 2024 · After 900 days of measurements, the drying creep is respectively 35% and 25% of the total creep for CEMI and CEMV concretes. It can be also noted that, even … WebIn this second article, we examine in greater detail the influence of concrete skin micro-cracking, linked with the non-uniformity of water content within the specimen. This cracking is responsible for the drying creep which results from a structural effect, also called “microcracking effect”, and which we prefer to call “structural creep” here.
WebNotably, we use this model and simulation results to demonstrate that the drying creep strain is not linearly dependent on the applied creep stress at the nanopore level. Our …
