Abstract:
Post-consumer glass represents a major component of solid waste, yet its use as an aggregate in concrete is problematic because of the strong alkali-silica reaction (ASR) between the cement paste and the glass aggregate. In a research project at Columbia University, the use of crushed waste glass as aggregate for concrete products was investigated. Fundamental aspects of ASR in concrete with glass aggregate were studied. It was shown that waste glass ground to U.S. standard sieve size No. 50 or smaller causes mortar bar expansions in the ASTM C 1260 test of less than 0.1%, which is less than that of reference bars without any glass. Also, green glass does not cause any expansion to speak of, and finely ground green glass has the potential of an inexpensive ASR suppressant. Specific concrete products with glass aggregate are currently under development. These include concrete masonry blocks with 10% mixed-color waste glass aggregate and “glascrete” products with 100% color-sorted glass aggregate for numerous architectural and decorative applications.

Presents recommendations for selection and use of the following in the production of precast concrete panels: (1) portland cement; (2) back-up concrete aggregates; decorative facing aggregates; (4) concrete admixtures; (5) reinforcement; forming materials; (7) jointing materials; (8) insulation; and (9) protective coatings. This is the second installment of a four-part series by Committee 533; future recommendations will cover design of panels and their fabrication; handling, and erection.

Two items of interest to designers in concrete are incorportated in the chapel of the Masonic Home and School in Ft. Worth, Tex. In order of construction they are: (a) Foundation design to protect a monumental structure from damage by a highly expansive soil which has wrecked one large building nearby and has badly cracked several others and (b) a structural frame of precast concrete members,having a decorative finish, and requiring concealed connections.

Describes the procedure for the manufacture and placing of precast exposed-aggregate: panels. used as face forms for concrete walls of buildings. Gives reas;ons for adoption of a three-hinged concrete barrel arch for the roof of the main basin building and the construction procedure for placing the reinforcrng and concrete of the arch including the setting of the steel for the Mesnager type hinges. Describes procedure for minimizing future movement of basin walls on account of shrinkage, changes in moisture content and live loa deformations. Includes descriptions of plastic mosaic decorative concrete as used for interior walls.

Portland cement stucco can be defined as a portland cement mortar applied in a plastic state to exposed walls or surfaces. Usually stucco is used for decorative purposes, but frequently only for protection against elements. With few execeptions, protection is of first consideration. Assuming this to be true, the necessary properties of durable stucco are easily found.
