Spectral Techniques for Serviceability and Durability Assessment of High-Performance Construction Materials
Using spectral techniques, one can obtain the frequency content of a material specimen. Spectral measurements were made on specimens of Portland cement and a polymer based materials. In...
An Extended Mixture Approach for Modeling of Fiber Reinforced Cementitious Materials
A rate-independent, anisotropic model for Fiber Reinforced Cementitious Materials (FRCMs) is presented. A continuum damage/plasticity model for the concrete and an effective fiber model...
High Performance Fiber Reinforced Cement-Based Composites
Fracture of cement-based composites reinforced by the relative high fiber volume is studied. Crack propagation and damage distribution were examined by laser holographic interferometry....
High Strength, High Denier Discrete Polymer Fiber in Cementitious Composites
A series of 3-point beam tests were performed on the cementitious composites specimens reinforced with high strength, high denier discrete polyester fibers. The fiber length, fiber volume...
Brittleness Index of Cementitious Composites
Series of direct tension tests were conducted to observe the softening response of different types of cementitious composites, namely, mortar, plain concrete, high strength concrete, normal...
Environmental Degradation of Concrete Pore Structure
This paper illustrates how Conductometric Phase Transition Porosimetry can be used to monitor changes in the pore structure of Portland Cement Concrete which result from repeated freezing...

Recent Development of Cement-Based Materials
Development of advanced techniques has enhanced the capability of more accurate characterization of engineering materials at both the microscopic and macroscopic levels. Through better...
Chloride Diffusion Constant for Concretes
Reinforced concrete exposed to chloride ions rapidly deteriorates once the chloride concentration level exceeds the corrosion threshold limit. The diffusion of the chloride ion through...
Sulfate Attack on Concrete Containing Fly Ash
The use of fly ash as a portland cement replacement in concrete may provide many technical and economic advantages. One such technical advantage is to improve the resistance of concrete...
Freezing and Thawing Durability of High Strength Silica Fume Concrete
Specimens from 27 batches of concrete with a water to cementitious (cement plus silica fume) ratio of 0.25 to 0.32, with and without entrained air, were tested for freeze-thaw durability...
