Time-Dependent Stress-Strain Behavior of Silicate-Grouted Sand
In practical applications, sodium-silicate grout injections are being used increasingly for underpinnings, improvement of bearing capacity of foundations, or as a supporting measure for...

Refined Stress Analysis of Human Aortic Heart Valves
The stress analysis of a human aortic valve is performed with a view toward the design, fabrication, and testing of a new prosthetic trileaflet aortic heart valve. Silicon castings of...

Streamflow Modification by a Silicone Antitranspirant

Alkali — Silica Reaction: A Major Cause of Concrete Deterioration

Lateritic Gravel Evaluation for Road Construction
The influence of geology, topography and climatic conditions on the mode of formation of typical lateritic soil profiles have been investigated, with emphasis on conditions in Ghana, West...

Selection of Chemical Grout for Mattmark Dam
Four chemical grouts, two nearly identical sodium silicates (Algonite and Consonda), and 2 polymers (Bakelite and Polythixon) underwent extensive laboratory evaluation. First, the grouts...

Sulfuric Acid Attack on Concrete Sewer Pipe
Research was performed to determine if selected surface treatments would react chemically with the portland cement and increase the resistance of a mortar to sulfuric acid attack. Four...

Agglomerate Size Changes in Coagulation
A concentric cylinder apparatus utilizing an electronic particle size analyzer was used to study the coagulation of finely divided silica particles by alum and FeCl3...

Physico-Chemical Properties of Soils: Soil-Water Systems
The heat of wetting, the diffusibility of hydrogen and isotopic prothium-deutrium exchange, indicate that a part of the water in a clay-water system should be considered as belonging to...
