Development of a Plane-Strain Device for Soft Rock
Work is now in progress to build a plane-strain apparatus for 'soft' (unconfined compressive strenghts below 35 MPa) rock and concrete, based upon a passive,...

Combined Compression-Shear Experiments on Mortar-Aggregate Interfaces
Material interfaces between matrix and aggregate particles in cementitious composites such as concrete are considered to be a very important component of the material microstructure, which...

Rate Effects in the Deformation of Rocks
This paper gives a brief review of creep and rate effects on the behavior of rocks, within a wide range of confining pressures and temperatures, and with a special emphasis on the physical...

Premature Failures of Outdoor Masonry Pavements
The authors have investigated and repaired a number of premature inservice failures of masonry paving systems in recent years. These systems have become common, built over underground...

Performance of Latex-Modified Thin-Set Mortars in Applications of Thin-Brick Veneer
The use of field-applied polymer-modified mortars for adhering thin brick or tile to building exteriors has become increasingly common in the last decade. The latex-modified mortars can...

Building Joint Movement
Moisture leakage in masonry claddings occurs not only through copings and facial separation cracks, but also through failed sealant joints in the veneer. The factors affecting joint movement...

U.S. Coast Guard Experience with Commercial FRP Vessels with Respect to Structural Reliability
The U.S. Coast Guard currently inspects over 1000 fiber reinforced plastic (FRP) vessels used in commercial passenger service. The designs include monohulls, catamarans, hydrofoils and...

Three Tools for Design Test Bed Analysis
Three analytical tools are outlined for use in design test bed work focusing on the design/production interface. The tools are substitution analysis, coupling analysis, and value chain...

Water Sensitivity of Asphalt Paving Mixtures
There are two mechanisms by which moisture can degrade the integrity of an asphalt concrete matrix: (a) loss of cohesive strength and stiffness in the asphalt film and (b) the failure...

Early-Time Strength and Elastic Modulus of Concrete With High Proportions of Fly Ash
Compressive strength and elastic modulus data are presented for four concrete mixtures with ratios (by volume) of Class C fly ash to total cementitious materials (portland cement plus...

Parameter Study of Stresses in Mass Concrete Using Two Fly Ash Mixtures
Finite-element modeling of the incremental construction procedure for mass concrete structures has been used to study the effects of three mechanical properties on thermal stresses. Material...

Durability of High-Strength Concrete Containing Fly-Ash and Silica Fume
The durability of high-strength concrete made with local materials were tested with regard to the freezing and thawing resistance of concrete in accordance with ASTM C666 procedure A....

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...

Size Effect in Concrete Structures and Influence of Loading Rate
The size effect law models the influence of the dimensions of the structure or specimen on the failure stress. This model can be used to quantify the brittleness of failure, and determine...

Uni- and Bi-Axial Compressive Fatigue of Fiber Concrete
Fatigue behavior of fiber reinforced concrete is studied under uniaxial and biaxial loadings. The S-N curves and the cyclic deformations of fiber concrete are compared to those of plain...

AE Instrumentation and Deconvolution Techniques
This paper describes the difficulties and solutions achieved in applying advanced Acoustic Emission (AE) signal analysis techniques to fracture mechanics. The test specimen is a double...

Displacement Measurement by Laser Interferometry and Image Analysis
Laser holographic interferometry was used for the evaluation of displacement fields on concrete and fiber reinforced concrete specimens. Transmission holography was used to analyze mortar...

Anomalous Structural Size Effect in Cohesive Materials Like Concrete
This contribution analyses on theoretical grounds the size effect trends in special cases where - unlike most experimental situations in fracture research - the specimen is not precracked...

ASCE Salary Survey 1989
The 20th biennial ASCE salary survey of the engineering profession conducted by the ASCE Committee on Employment Conditions during the fourth quarter of 1989 is presented. It consists...

More Than a Public Hearing
Too often, required community input is reduced to the sometimes dreaded public hearing. Many formal public-involvement programs are comprised of no more than this minimal, yet essential,...
