Description SGl-Standard Specification ACI 503.4 is intended tobe used essentially in its entirety, by citation in theproject specification, to cover all usual requirements forrepairing concrete with epoxy mortars. Individual sec-tions, parts, and articles should not be copied into projectspecifications since taking them out of context maychange their meanings. SG2-However, adjustments to the needs of a
Description Concrete surfaces to which epoxies are to be appliedshall be newly prepared substrate free of loose and unsoundmaterials and contamination that affect cure or adhesion ofepoxy. Prepare surfaces by mechanical abrasion. 3.1.2Mechanical abrasion—Use abrasive blasting, shot-blasting, or other approved means.3.2—Evaluate surface before coating application3.2.1Evaluate all prepared concrete surfaces before applica-tion of coating to ensure

Description Impact, explosions, and earthquakes impose dynamic effects on concrete structures. Impact loading on a parapet can occur if it is struck accidentally by a crane. Seismic loading produces significant strain rates in concrete shear-walls and other lateral force-resisting elements. Explosive loading, due to accidental detonation of industrial vapor clouds or terrorist bombing, produces high

Description In this report, the state-of-the-art in finite element modeling of concrete is viewed from a fracture mechanics perspective. Although finite element methods for modeling fracture are undergoing considerable change, the reader is presented with asnapshot of current thinking and selected literature on the topic .As early as the turn of the 19th century, engineers

Description Fracture Mechanics of Concrete: Concepts, Models and Determination of Material Properties. Concrete structures are full of cracks. Failure of concrete structures typically involves stable growth of large cracking zones and the formation of large fractures before the maximum load is reached. Yet design is not based on fracture mechanics, even though the basic fracture
Description Accounting for the effects of torsion is essential to the safe design of structural concrete members, requiring a full knowledge of the effects of torsion and a sound under-standing of the analytical models that can easily be used for design. For over three decades, considerable research has been conducted on the behavior of reinforced

Description Masonry is a generic term used to describe a type of construction where clay, or concrete masonry units, or natural stones are bonded together to form a load-bearing structure or a component in a structure. Non-load-bearing masonry includes partitions and veneers. Although masonry is used in flexural applications such as retaining walls, roof and

Description Fiber-reinforced polymer (FRP) composites have been proposed for use as prestressing tendons in concrete structures. The promise of FRP materials lies in their high-strength, lightweight, noncorrosive, nonconducting, and nonmagnetic properties. In addition, FRP manufacturing, using various cross-sectional shapes and material combinations, offers unique opportunities for the development of shapes and forms that would be
