...JMV Gómez-Soberón In this work, an experimental analysis is described of specimens of recycled concrete (RC) made with replacement of natural aggregate with recycled aggregate originating from concrete (RCA). An experimental analysis to obtain the shrinkage and creep properties (basic and by drying...

... characterizing workability. KEYWORDS: cement paste, concrete, creep, rheology, set, viscosity, yield stress There have been many studies of the flow behavior of cement paste and concrete since the extensive review some years ago by Tattersall and Banfill 1983. The objective of the present paper is to review...

... included measurements over time of tensile strength, drying shrinkage, tensile modulus of elasticity, and tensile creep. The model's predictions were checked by placing the studied mortars in a simulated repair situation. The influence of polymers on physical properties, the stress developed while curing...

... loads, the top strains increased on 100 pipes by 10% and bottom strains remained unchanged. An experiment has been carried out on site to determine the magnitude of the creep occurring in such pipes. In a period of six months the creep strains have increased by three times the previous strains resulting...

...ZP Bažant; J-C Chern; Y-G Wu An alternative simple formula for the compliance function for basic creep of concrete is proposed and evaluated. It consists of a hyperbolic sine combined with the double power law. For short creep durations it asymptotically approaches the double power law...

...MA Tasdemir; S Akyüz; N Uzunhasanolu In this work, the creep of lightweight aggregate concrete under constant stress is described by a logarithmic function of time, and the variations of the coefficients with age are experimentally determined. Using the relation thus obtained, an attempt is made...

... the shrinkage of the superplasticized concretes is comparable to or less than that of the reference concrete. The Type I portland cement concrete containing the melamine-based superplasticizer exhibits essentially the same creep as the reference concrete. The freeze-thaw durability of the superplasticized...
