Thermal Analysis for RCC?A Practical Approach
Roller compacted concrete (RCC) structures, by nature of the construction method, tend to be monolithic structures or structures with minimal contraction jointing. Recurring questions...
Santa Cruz Dam Modification
Santa Cruz Dam was the first concrete arch dam in the United States to be modified using an roller compacted concrete (RCC) buttress. Innovative techniques included forming the stepped...
Design of the Boney Falls RCC Emergency Spillway
The Boney Falls Emergency Spillway was designed as a mass roller compacted concrete structure. Alternative designs considered include a fuse plug, lowering the embankment and paving with...
Rehabilitating Small Earth Embankments with RCC
The rehabilitation of existing earth dams using roller compacted concrete (RCC) is gaining wider acceptance in the engineering and construction community. Presented herein is a discussion...
Roller Compacted Concrete III
This proceedings,
Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...
Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...
Grouting, Soil Improvement and Geosynthetics
The proceedings of the 1992 ASCE Specialty Conference on Grouting, Soil Improvement and Geosynthetics, addresses advances in the state-of-practice, research and technological developments...
Indigenous Planetary Construction Material Through Soil Modification
This paper will discuss the theory of soil modification and its potentials for producing planetary construction materials. The authors will also present the results of prelimnary experriments...
Mechanical Properties of Compacted Lunar Simulant Using New Vacuum Triaxial Equipment
Mechanical stress-strain-strength properties of Arizona Lunar Simulant (ALS) are investigated by using a newly developed vacuum triaxial device that allows compaction under different initial...
Grouting Against Hazwaste
Grouting has only recently entered the hazardous-waste arena, mainly in the form of positive cutoff slurry walls. At an industrial landfill near Niagara Falls, N.Y., a three sided, single-line...
Better Cover-Ups
Designing the final cover for a solid waste landfill or remediation site is often trickier than designing its lining because a cover will undergo more unpredictable stress and distress...
Glass-Fiber Reinforcing Rod: Characterization and Application to Concrete Structures and Grouted Anchors
This paper presents the physical and mechanical characteristics of a new glass-fiber reinforcing rod which was developed to be used as a rebar for concrete structures or a tendon for grouted...
Mining for Building Expansion
Engineers adapted mining techniques to tunnel under a vibration sensitive manufacturing operation to create new working space below. IBM workers needed more working space at their Vermont...
Cables and Anchorages
The following types of cables are generally used in cable stayed bridges: Parallel bars; Parallel seven wire strands; Parallel or semi-parallel wire cables; Locked coil strands and ropes;...
Freeze-Thaw Effects on Clay Covers and Liners
The properties of clay covers and liners used for containing solid waste materials are highly susceptible to environmental stresses. Even when clay layers are protected from drying, freezing...
Fly Ash Grouts for Subsidence Control
A laboratory investigation was undertaken to examine procedures for evaluating candidate grouts and to develop quality grouts for use in abandoned mines. The objective of this grout application...
Acid Mine Drainage Control Utilizing Fly Ash
Acid mine drainage is a serious environmental problem confronting the Appalachian region. Fly ash, the air particulate residual from the combustion of coal, is also an environmental concern...
Fly Ash in Roller Compacted Concrete Pavement
This paper presents the state of practice on the use of fly ash in roller compacted concrete (RCC) pavements. Placed using asphalt pavers and compacted using asphalt rollers, RCC pavement...
Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....
