Residual Soil Settlment Related to the Weathering Profile
Residual soils are the in-place residue from rock weathering. They differ greatly from the better understood deposited soils in that their particle arrangements and mineralogy reflect...
Prediction of Movement in Expansive Clays
The movement of expansive soils is usually due to a change of suction near the soil surface. The properties of the soil that govern the amount and rate of movement are the suction compression...
A Study of Alkalinity Leaching and Residual Strength of Alkaline Stabilized Sludge
The addition of sufficient amounts of quicklime or other alkaline earth oxides to dewatered sludge raises both the pH and temperature of the sludge, resulting in microbial inactivation....
Practical Method for Scour Prediction at Bridge Piers
A practical method is presented for prediction of local scour at bridge piers which is based on a comparison of many well known equations and supported by field data. This equation includes...
Comparison of Headcut Advance Testing and Soil Test Results
This paper presents the results of a study conducted in a flume to determine headcut advance rates of two base soils compacted at various compaction moistures and placement energies. The...
Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...
Stiffness of Low Rise Reinforced Concrete Shear Walls

Settlement Analysis
The U.S. Army Corps of Engineers Manual, Settlement Analysis, presents guidelines for calculation of vertical displacements and settlement of soil under shallow foundations. As soil is...
Improving Development Characteristics of Reinforcing Bars
Prepared by the Civil Engineering Research Foundation. Sponsored by CERF, This report describes the development and implications of a new concrete...

Wet Mix Shotcrete Used in Subsea Tunnel Environments
To reject the claim that the use of accelerator in shotcrete reduces the compressive strength with time, lately cored samples were taken from an 18 to 19 years old concrete. A wet mixed...
The Influence of Water Glass on the Technological Parameters of Shotcrete
Shotcrete used in tunneling must follow a clearly defined early strength development in order to comply with stresses from rock deformations and drilling and blasting. Accelerators are...
Shotcrete Tests at the Fish Ecca Tunnel
The Fish-Ecca Tunnel is situated in the Eastern Cape and forms part of the Lower Fish Irrigation Scheme. About 25% of the 5032 m tunnel had to be lined with shotcrete. Between February...
An Identity Chart for Steel Fibers
Improvements in ductility and toughness by adding steel fibers to the shotcrete mix are sufficient to enable steel fibers to be used as replacement for steel mesh reinforcements. Steel...
Steel Fiber Reinforced Shotcrete?For Rock Support and Fire Protection
Rapid development in concrete technology and development of equipment has led to a change from dry hand-operated to wet robot shotcreting in Norway. Shotcrete of more than 100 MPa cube...
ASTM C666 (A) Freeze-Thaw Durability of Air-Entrained Wet- and Dry-Mix Shotcrete
In order to assess the freeze-thaw durability of shotcrete, six samples of dry-mix shotcrete and one sample of wet-mix shotcrete were mixed outdoors at Hydro-Quebec's research institute...
CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...
Seismic Behavior of Weak-Column Strong-Beam Frames
An experimental evaluation of the seismic performance of moment-resisting steel frames using Weak-Column Strong-Beam joints is described. A simulated seismic response is imposed on five...
Seismic Behavior of High Strength Concrete Columns
Information on the ductility of high strength columns in seismic areas has been scarce. The available information is based mainly on small test columns subjected to monotonic concentric...
High-Strength Concrete Joints Under Cyclic Loading
This experimental investigation was undertaken to check the validity for high-strength concrete beam-column joints of recommendations made by ACI-ASCE (American Concrete Institute-American...
