Control of Early-Age Cracking in Watertight Concrete Structures

Early-Age Cracking in Reconstructed Concrete Bridge Barrier Walls

An assessment of newly reconstructed reinforced concrete barrier walls on a highway bridge near Montreal indicated intense transverse cracking only a few days after concreting. Subsequent inspection of other concrete bridges in urban areas confirmed that such cracking is not uncommon. Analytical models, together with field and estimated data, were used to study the magnitude and roles of the fa...

Evaluating Cracking In Concrete

Cracking Assessment in Concrete Structures by Distributed Optical Fiber

In this paper, a method to obtain crack initiation, location and width in concrete structures subjected to bending and instrumented with an OBR system (Optical Backscattered Reflectometer) is proposed. Continuous strain data with high spatial resolution and accuracy are the main advantages of the OBR system. These characteristics make this Structural Health Monitoring (SHM) technique a useful t...

Effect of Lightweight Aggregate on Early-age Cracking of Mass Concrete

Early Age Shrinkage Behavior of Triple Blend Concrete

The early age shrinkage is responsible for the early age cracking of concrete. It is very critical for durability of concrete. The change in volume of concrete due to evaporation of water or dehydration process is known as shrinkage. To reduce the early age shrinkage utilized the supplementary cementitious material (SCM) in concrete. In present research industrial and agricultural waste byprodu...
