Creep Behaviour of Fly Ash-Based Geopolymer Concrete
Civil Engineering Dimension, 2010 Fly ash-based geopolymer concrete is manufactured using fly ash as its source material and does not use Portland cement at all. Beside fly ash, alkaline solution is also utilized to make geopolymer paste which binds the aggregates to form geopolymer ...

Tensile Creep of High-Strength Concrete
Journal of Advanced Concrete Technology, 2006 Tensile creep tests on high-strength concrete have been performed. Besides up-to-date creep data which have been generated a new phenomenon has been discovered, i. e. shrinkage of loaded specimens is larger than of non-loaded ones. It seems that this phenomenon is in agreement with Powers' creep theory.

Experimental Study on a Prediction Model of the Shrinkage and Creep of Recycled Aggregate Concrete
Applied Sciences, 2019 The significant difference between recycled aggregate and natural aggregate is the content of the attached mortar layer. With the increase of the replacement rate of recycled aggregate, the shrinkage and creep of recycled aggregate concrete is ...
