The Cover Trials
Soil erosion-control covers have been used over closed landfills for years as a means of limiting soil loss and contaminant runoff. Since 1994, the U.S. Environmental Protection Agency...
Relining a Relic
By the mid-1980s most of the Boston Low Service water supply network had been in operation for more than 100 years�with little regular maintenance. Many of the system's air...
Pyramid Power
The pyramids of Giza in Egypt were built with limestone from nearby quarries, not concrete as some have theorized. The three main pyramids of Giza mark a highpoint of pyramid building...
Behavior of Instrumented Model Piers in Manufactured Rock with a Soft Layer
A laboratory test apparatus has been used to study the side resistance of piers socketed into manufactured soft-rock masses. The results of four tests are reported, three of which included...
Study of Three Dimensional Crack Tip Location of Mortar by Acoustic Emission
Plain mortar specimens were tested under three-point bending. Experimental variables include the width of the specimen and the notch-to-depth ratio. The experimental results of 12 specimens...
Reliability-Based Design for Feeeze-Thaw Concrete
Observation of pavements in Iowa shows results from the test for freezing and thawing of concrete, ASTM C-666, is not always consistent with field performance. Similar concrete made with...
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...
Strength, Durability and Creep of Fly-Ash Concrete: Part I
In this paper, strength of concretes and mortars containing various proportions of fly ash were examined. For strength tests four types of Canadian and one type of American ash were used...
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...
Sprayed-On Polymer Mortar Construction
Sprayed-on polymer mortar has been used to construct low-cost, lightweight structures in a variety of locations. The addition of the two-component additive to one cubic yard of mortar...
Los Angeles' Small Main Programs
Large quantities of small diameter mains within Los Angeles' water distribution network has necessitated the development of new main improvement programs. The introduction...
Delamination and Remedial Repair of GFRC Cladding Panels
The construction of a six story, steel framed office structure included an exterior cladding of prefabricated glass fiber reinforced concrete (GFRC) panels. The typical full-size panel...
