Sentence examples for under restrained conditions from inspiring English sources
Autogenous deformation under restrained conditions often leads to cracking and durability problems in concrete structures.
SCC reaches lower values for E-modulus, compressive and flexural strengths but higher values for shrinkage, creep and strain under restrained conditions.
The purpose of this study is to evaluate the performance of using different fibers in reducing the drying shrinkage and cracking under restrained conditions.
It was found that, even under restrained conditions, the threshold alkali level proves to be a suitable reactivity parameter for designing concrete mixes that are not susceptible of deleterious ASR expansion.
The primary objective of this study was to ascertain whether the Threshold Alkali Level (TAL) of the concrete aggregates may be taken as a suitable reactivity parameter for the selection of aggregates susceptible of alkali-silica reaction (ASR), even when ASR expansion in concrete develops under restrained conditions.
The influence of the paste volume and the cement type on E-modulus, flexural and compressive strengths, drying shrinkage, creep and stress development under restrained conditions is investigated on three SCC mixtures and three mixtures of CVC with identical water-to-cement-ratio.
Method of shrinkage cracking assessment is improved when parameters influencing cracking behaviour of repair material under restrained condition are reckoned.
This has given credence to high strength or high dense concrete as being durable, but its field performance under restrained condition and under loading has not always reflected this anticipation.
Concrete mixes made with different alkali contents and two natural siliceous aggregates with very different TALs were tested for their expansivity at 38 °C and 100% RH under unrestrained and restrained conditions.
At the same time, the tendency of ECC mixtures to crack under restrained shrinkage conditions was also investigated using restrained shrinkage rings.
Comparative bulge forming experiments under various forming conditions were carried out with the tooling to validate this project and the results suggest that restrained conditions on the tube ends highly affect the FBF, while the ratio of the two loads dominates the BFAL.
