Engineers, contractors, researchers, and students will benefit from learning about the latest research and test methods that will pave the way for a performance-based approach in specifying durability in concrete mixtures.
Effective construction practices are essential to the long-term performance of the concrete pavement structure.
However, these short-duration tests (the concrete prism test, mortar bar method test, accelerated mortar bar test, new concrete cylinder test, and new autoclave concrete prism test) have limitations in their ability to provide a direct measure of how a job’s concrete mixture might perform in the field over the long term.
These sessions will shed light on developments in the areas of new test methods that are focused on assessing the alkali-silica reactivity potential of a job’s concrete mixture and new nondestructive test methods to evaluate the extent of damage in job concrete mixtures.
Presentations relate to the FRP strengthening of existing masonry elements, and the use of FRP bars as internal reinforcement in new masonry construction.
Material is presented in an order that follows typical design process with procedures introduced as the designer will need them in the course of a building design.
Papers on evaluation methods, prediction models, reliability analysis, and code calibration will be presented.
ACI Subcommittee 440-M, FRP-Repair of Masonry Structures, is sponsoring this technical session focusing on various applications of fiber-reinforced polymer (FRP) systems for masonry structures.
The main audience for the session is contractors, but concrete producers, materials suppliers, designers, architects, and scientists will also have interest in this session.
The principal objectives of the existing standard test methods for evaluating alkali-aggregate reactivity (AAR) in mortars and concrete is to identify the susceptibility of aggregates to undergoing alkali-silica reaction (ASR), to identify the effectiveness of supplementary cementitious materials (SCMs) in mitigating ASR, and quantify the suitable dosage level of SCMs in the concrete mixtures.The basic one-way shear equations in the ACI 318 Building Code have not changed since 1971, while other codes in the world have made changes.
