Assessment of the expansion related to alkali-silica reaction by the Damage Rating Index method.
March 1, 2005... Abstract Among all the quantitative methods that have been proposed for the quantification of the internal deterioration caused by alkali-silica reaction (ASR), the Damage Rating Index (DRI) appears to be one of the most valuable. This...

Recycling of municipal solid waste incinerator ash in hot-mix asphalt concrete.
March 1, 2005... Abstract This research investigated the use of incinerator ash as a partial replacement of fine aggregate in hot-mix asphalt concrete. Municipal solid waste (MSW) Incinerator ash was obtained from an incinerator facility at Sultan Qaboos...

Advanced wood engineering: glulam beams.
March 1, 2005... Abstract The main objective of this experimental study is the determination of the flexural properties of reinforced and unreinforced glued-laminated beam. Why reinforcing glulam beam? Reinforced glulam beams cost less because the use of...

Cylindrical specimen for measuring shrinkage in repaired concrete members.
March 1, 2005... Abstract This study presents a new method for measuring the shrinkage of repair materials in repaired concrete structures. Three cylindrical models and a halt-scale beam were constructed; these included three types of repair materials and...

Application of spent grains to increase porosity in bricks.
March 1, 2005... Abstract The dumping of spent grains is going to be more difficult because of the increasing number of cattle. That means new ways of dumping must be developed. The goal of the work was to test the technical properties of bricks...

Influence of variability of oil shale fly ash on compressive strength of cementless building compounds.
March 1, 2005... Abstract The variability of fractional, chemical and mineralogical compositions of Israeli oil shale fly ash (OSFA) were examined. The effect of Ca[O.sub.free] content in OSFA and the age of the test specimens, prepared on the basis of...

Behaviour of high strength axially loaded concrete columns confined with helices.
March 1, 2005... Abstract This paper presents an experimental study of the behaviour of four HSC columns confined by helical reinforcement of 500 MPa and with 500 MPa longitudinal reinforcement. Two NSC columns confined with a 500 MPa-grade helix and two...

Potential application of acid jarosite wastes as the main component of construction materials.
March 1, 2005... Abstract The purpose of this work was threefold: (1) To test quite new method of materials preparation only from the mixture of hazardous or polluting industrial wastes: of high acid jarosite processing waste (JW) of Zn-industry, alkaline...

Properties of gap-aggregate gradation asphalt mixture and permanent deformation.
March 1, 2005... Abstract Aggregate of natural crush stone in hot mix asphalt is applied to gap gradation mixed with the AC-20 binder, in accordance with Marshall mix design. Laboratory tests were conducted, and the single-factor variance analysis (ANOVA)...

Determination of fine aggregate angularity in relation with the resistance to rutting of hot-mix asphalt.
March 1, 2005... Abstract Rutting in asphalt pavements continues to create problems for pavement agencies. One factor that has been identified in determining asphalt pavement rutting susceptibility is the fine aggregate angularity (FAA) in the asphalt...
