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...
Roller Compacted Concrete Mix Design
This paper presents a concise and proven mix design process. It covers all the steps necessary to produce a good roller compacted concrete (RCC) mix design for mass and structural applications,...
RCC Test Specimen Preparation?Developments Toward a Standard Method
As there is no widely recognized standard for the preparation of laboratory test specimens for roller compacted concrete (RCC) mixtures, criteria for developing such a standard are listed....
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....
Design of Pena Colorada Tailings Retention Dam
This paper discusses the details involved in the design of a 66 meter high RCC dam to be used to create storage for slurry from an iron ore mining operation located near Manzanillo, Mexico....
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...
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...
Hydraulics of Stepped Spillways for RCC Dams and Dam Rehabilitations
Stepped spillways are natural extensions of roller-compacted concrete (RCC) placement techniques. Stepped spillways were first used with concrete dams, and designers are eager to use the...
Final Design and Construction of Gibraltar Dam Strengthening
The results of a 1983 safety evaluation of Gibraltar Dam indicated that the dam did not meet seismic safety standards. A remedial scheme involving the addition of a roller compacted concrete...
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...

Principles of Holistic Medicine Applied to Infrastructure Maintenance: A Test Case
A humorous consideration of the question of whether holistic medicine�that is, the treatment of the entire physical and emotional configuration of the patient instead of the solely medical...
Learning to Love NDT
Sometimes overblown claims and the practical limitations of early nondestructive tests for concrete have left many civil engineers leery of NDT methods. While some are aware that NDT has...
Tomorrow's Schools
While what's wrong with education looms as a national concern, many communities are doing something positive about it. They're constructing new schools designed...
Small Systems Struggle
Across the U.S., small communities are caught in a bind. Local governments bear the primary day-to-day burden of caring for public works, responsible for 70% of the nation's...
Rail Revival
Rail transit appears to be on the upswing. More than 30 cities are building, extending or seriously considering new rail-transit systems, according to a recent report from the Regional...
Designing Reinforced Rock
The reinforced rock arch design method has been used to stabilize coal mine excavations for 40 years, but so far has been applied to only a few tunnels. The use of rock reinforcement develops...
