Freeze-Thaw Resistance of Concretes with BFSA
Abstract—Air-cooled Blast Furnace Slag Aggregate (BFSA) is usually referred to as a material providing for unique properties of concrete. On the other hand, negative influences are also presented in many aspects. The freeze-thaw resistance of concrete is dependent on many factors, including regional specifics and when a concrete mix is specified it is still difficult to tell its exact freeze-th...
متن کاملFreeze-Thaw Bayesian Optimization
In machine learning, the term “training” is used to describe the procedure of fitting a model to data. In many popular models, this fitting procedure is framed as an optimization problem, in which a loss is minimized as a function of the parameters. In all but the simplest machine learning models, this minimization must be performed with an iterative algorithm such as stochastic gradient descen...
متن کاملStreptococcus thermophilus.
Streptocus tmophilus, as a species designation (Orla-Jensen, 1919), has included those members of the nonhemolytic streptococci that possess the unusual combination of characteristics of extreme salt sensitivity, nonobligate thermophily, a rigorous fermentative pattern with respect to certain sugars (Sherman, 1937), and, based upon attempts to culture on synthetic media, a notoriety for nutriti...
متن کاملFreeze-Thaw Durability of Air-Entrained Concrete
One of the most damaging actions affecting concrete is the abrupt temperature change (freeze-thaw cycles). The types of deterioration of concrete structures by cyclic freeze-thaw can be largely classified into surface scaling (characterized by the weight loss) and internal crack growth (characterized by the loss of dynamic modulus of elasticity). The present study explored the durability of con...
متن کاملImportance of Realistic Freeze-Thaw Protocols
The relative effect of a freeze-thaw cycle on photosynthesis, respiration, and ion leakage of potato leaf tissue was examined in two potato species, Solanum acaule Bitt. and Solanum commersonii Dun. Photosynthesis was found to be much more sensitive to freezing stress than was respiration, and demonstrated more than a 60% inhibition before any impairment of respiratory function was observed. Ph...
