Concrete pumping and its effect on the air void system

Jul 05, 2018 · Background. Pumping is a quick and efficient technique to place concrete in formwork, and it is well-known that pumping can significantly change plastic concrete properties [1,2,3,4].Concrete pumping, typically performed utilizing a dual-piston pump, is an elaborate process that can be, for the sake of simplicity, divided into four distinct phases.

Mar 08, 2021 · The safety of drinking water is constantly being evaluated. In the last few decades, however, many drinking waters sources in the world, including in China, have undergone serious eutrophication and consequently water quality deterioration due to anthropogenic induced stressors such as elevated external nutrient inputs. In this study, we used the state-of-the-art complex, dynamic, …

Justification and refinements of model B3 for concrete

Following statistical evaluation in part 1, this part deals with the improvement of prediction by updating one or two parameters of the model on the basis of short term tests and theoretical derivation of some formulae. The updating of model parameters is particularly important for high strength concretes and other special concretes containing various admixtures, superplasticizers, water
