Prediction of concrete service-life | SpringerLink

This paper discusses development of accelerated tests and mathematical models for predicting the durability of concrete. Durability, service life, and degradation factors are defined and accelerated test methods are contrasted to conventional comparative methods. Factors and mechanisms of concrete degradation are reviewed, as are efforts to quantify these phenomena. Deterministic and

Concrete pumping prediction considering different

May 20, 2018 · Choi et al. examined the effects of coarse aggregate sizes on the pumping performance with three different maximum coarse aggregates, incorporating 10, 20, and 25 mm and reported that a high viscosity was required for the acceptable stability of large-sized aggregate concrete, which results in demanding high pressures and concluded that the maximum coarse aggregate size has a significant …

[PDF] Models for Strength Prediction of High-Porosity Cast

A study was undertaken to develop a prediction model of compressive strength for three types of high-porosity cast-in-situ foamed concrete (cement mix, cement-fly ash mix, and cement-sand mix) with dry densities of less than 700 kg/m3. The model is an extension of Balshin's model and takes into account the hydration ratio of the raw materials, in which the water/cement ratio was a constant

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.
