The frequent maintenance required on asphalt concrete (AC) pavement sections has made reconstruction with portland cement concrete pavement (PCCP) a feasible alternative. However, many constructability issues need to be addressed in order to realize

The fiber contribution to the ultimate limit state capacity of precast and cast-in situ tunnel linings is analytically investigated. By means of a numerical model, capable of computing the interaction curves of reinforced concrete cross sections subj

Bayesian Statistical Framework to Construct Probabilistic Models for the Elastic Modulus of Concrete

The commonly used Pauw’s formula to predict elastic modulus of concrete is very general and does not address the complexity of modern concretes, such as high-strength concrete, use of different types of aggregates and admixtures, etc. This paper de

Summary: A special experimental technique has been developed that enables the preservation of the compressive stressinduced microcracks in concrete as they exist under applied loads. This technique involves injecting a molten-metal alloy into the ind

To study micromechanical behavior of concrete, stereological measurements were conducted,i.e., crack orientation, length, density and other features. A special experimental technique was developed which made possible the preservation of the compressi

The experimental technique described in this paper makes it possible to preserve the compressive stress-induced microcracks in concrete as they exist under applied loads. The results can be used to better understand and quantify the general relations

Two different investigations on the scaling properties of damage in concrete have been carried out. In the case of uniaxial tensile tests, a laser profilometer was adopted to scan the post-mortem fracture surfaces. In the case of compression tests, a

The cement paste in the interfacial transition zone (ITZ) around aggregate particles has a significantly higher porosity than bulk cement paste. This elevated porosity will effect the transport properties of concrete. The penetration of Wood's metal
