In-Service Durability Evaluation of Armourstone
A summary flow diagram for rock evaluation, general to all rock types and engineering applications of rock is introduced. It is then applied to armourstone. Increasing detail within this...

Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...

The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...

The Construction of New Victoria Dam, Australia
The paper discusses various aspects of the construction of the New Victoria Dam, a 52 m high, high-paste content RCC dam constructed near Perth, Western Australia. The mix design and its...

Design of Miel II?A High RCC Dam
Miel II Dam is a 141 m high RCC structure designed for the tropical mountains of central Columbia. Interesting features are its height (considerably higher than any existing RCC Dam),...

Concrete-Faced RCC Dams
In the past 10 years, roller compacted concrete (RCC) has gained wide acceptance as a cost effective material for constructing and rehabilitating dams. Since the first RCC dams had seepage...

RCC Mixes and Properties Using Poor Quality Materials?Concepcion Dam
This paper discusses aggregate studies, mix investigations, and material property tests for the relatively poor quality materials available for use in RCC at Concepcion Dam....

Thermal-Structural Analysis Methods for RCC Dams
Current procedures for evaluating temperature control and the placement of contraction joints in roller compacted concrete dams are not always evaluated with the aid of detailed analysis...

Simulated Field Trials of Non-Destructive Concrete Test Methods for Highway Structures
The data presented results from a two year Strategic Highway Research Program investigation into suitable NDT methods for determining the early age, and residual strengths of highway structures....

Review of NPP Concrete Degradation Factors and Assessment Methods
Degradation of concrete in nuclear power plant (NPP) structures can be an age-related phenomena. Several research programs have been initiated by the U.S. Nuclear Regulatory Commission...

Micromechanics and Effective Properties of Elastic Particulate Composites
A new micromechanical framework is proposed to investigate the effective mechanical properties of elastic particulate multiphase composites. Exact ensemble-volume averaged field equations...

Quantitative Stereology of Concrete Microcracking
Stereological methods enable extrapolation of quantitative microcrack characterization from two dimensions to three dimensional space. However, because these quantifying techniques are...

Experimental Determination of the Relation Between the Damaged Zone and the Aggregate Size in Concrete Through Acoustic and Mechanical Techniques
The size of aggregates in concrete has an influence on the behavior of the material. The width of the localized band can be related to this characteristic. Different experimental techniques...

Mechanical Characterization of the Soft Tissue in Horse Hooves
The laminar corium tissue of the equine distal digit (or horse hoof) has been tested uniaxial tension. The laminar corium tissue lies between the hoof wall and the underlying bone of the...

Random Aspect of the Stress Inside Granular Media
Micromechanics of granular media arose from the necessity of a better understanding of the relationship between the global behaviour of such materials and the physical phenomena which...

Nonlinear Behaviour of Schneebeli Packings
We present some experimental proofs of the influence of the disorder of contacts on the mechanical (non-local) behaviour of packings of cylinders. In particular, this disorder is responsible...

Particle Analysis of Material Behavior?A Note on Continuum Assumptions
Continuum models of materials have dominated our approach to the analysis of material behavior. Recently a number of discrete particle methods have been proposed which offer a different...

On a Micromechanical Basis of Stochastic Constitutive Laws
A procedure for derivation of stochastic constitutive laws is outlined on the basis of graph-representable linear elastic microstructures. Central to the procedure is the concept of a...

Nonlinear Behavior of Thin Slender Free Surface Non-Newtonian Elliptical Rings
This paper analyzes the nonlinear motion of a slender concentric thin elliptical ring of an incompressible, non-Newtonian fluid. This study includes the physical effects of surface tension,...

Laser Interferometric Characterization of Acoustic Emission Transducers
The characterization of the exact response of commercially available, piezoelectric and thin film, acoustic emission transducers is of fundamental importance for the nondestructive evaluation...
