INFLUENCE OF WHISKER REINFORCEMENT ON THE ABRASIVE WEAR BEHAVIOR OF
SILICON NITRIDE- AND ALUMINA-BASED COMPOSITES
Abstract
 The abrasive wear of brittle materials is generally modeled as an inverse function of both the bulk hardness and fracture toughness.
 According to these models,an increase in the hardness or fracture toughness of a material will enhance its wear resistance.
 However,less is known about how whisker-reinforcement influences the properties that ....etc

Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of reinforcement must be prevented in order to have a durable struct ....etc

ABSTRACT:
A new technique for reinforcing rubble stone masonry walls (double and triple-leaf walls), when it is required to keep the fair-face masonry. The reinforcement technique consists of a continuous mesh made of tiny steel cords embedded perfectly in the mortar joints after a first repointing, and anchored to the wall by means of galvanized steel eyebolts driven into the facing. A second repointing covers the cords and the heads of the eyeb ....etc

FIRE RESISTANCE REINFORCEMENT
Four decades and 12 moonwalks later, the technology still exists in new, advanced products. In 1999, Houston-based International Paint, LLC, acquired the Chartek fireproofing brand. The company’s latest product derived from Chartek technology is coined Interchar and geared toward making America’s high-rise buildings and public structures safer.
Fabrication shop application of Interchar fireproofing material to structural steel beams. Since Interch ....etc

Composite Rods as a Steel Substitute in Concrete Reinforcement



Introduction
The concrete construction industry is dealing with a very significant challenge regarding the
deterioration of structures. Nowadays a large number of bridges, buildings and other structural
elements require rehabilitation and repair and its maintenance have become an increasingly serious
problem. Once subjected to repeated loading and to aggressive environmental agents, concrete
