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 ...

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 ...

Time scale in concrete fracture: a model based on partitions of unity [PDF]

, 2001
Intense research efforts have been put in the formulation of theories for crack initiation and propagation in concrete. Yet, little attention has been paid to the time-dependence of fracture, despite evidence of its significance.

Deflection control of prestressed concrete elements considering uncertainties

, 2019
Excessive deflections can affect serviceability e.g. by causing damage to connecting building components and resulting in problems related to drainage in roof slabs.

Prestress loss of post-tensioned clay diaphragm and fin brickwork [PDF]

, 1994
Unlike calcium silicate and concrete block masonry which undergo shrinkage with time, clay brickwork has been known to expand instead. Expansion of brick units in prestressed masonry will cause an increase in the prestressing force instead of prestress ...

Coupling creep and damage in concrete under high sustained loading: Experimental investigation on bending beams and application of Acoustic Emission technique

EPJ Web of Conferences, 2010
Creep and damage in concrete govern the long-term deformability of concrete. Thus, it is important to understand the interaction between creep and damage in order to design reliable civil engineering structures subjected to high level loading during a

Predicted vs Measured Initial Camber in Precast Prestressed Concrete Girders [PDF]

, 2017
Prestressing of concrete is the introduction of permanent internal stresses in a structure or system in order to improve its performance. Concrete is strong in compression but weak in tension.
