Durability of Concrete Structures Incorporating Conventional and Advanced Materials
Abstract: Preface Durability of Concrete Structures Incorporating Conventional and Advanced Materials Sustainability is one of the salient requirements in modern society. Structures frequently deteriorate because of aggressive ... -
Report on Accelerated Techniques for Concrete Paving
Abstract: Concrete mixtures used in accelerated concrete pavement construction may be more susceptible to durability-related distress than conventional concrete. Further, the ability to detect durability-related problems during ... -
Qualification of Precast Concrete Diaphragm Connections and Reinforcement at Joints for Earthquake Loading (ACI 550.4M-18) and Commentary (ACI 550.4RM-18)
Abstract: ACI 550.4M defines the minimum testing requirements and the acceptance criteria for different performance levels for connections or reinforcement at joints where used to connect precast concrete DT members subject to ... -
Strength Evaluation of Existing Concrete Buildings
Abstract: Background and limitations—Engineering judgment based on rational, scientific principles is critical in the strength evaluation of concrete structures. Such judgment of a qualified licensed design professional is needed ... -
Guide to Protection of Reinforcing Steel in Concrete against Corrosion
Abstract: This guide discusses the factors that influence corrosion of reinforcing steel in concrete, measures for protecting embedded reinforcing steel in new construction, techniques for detecting corrosion in in-service structures, ... -
Qualification of Post-Installed Mechanical Anchors in Concrete and Commentary
Abstract: ACI 355.2 prescribes testing and evaluation requirements for post-installed mechanical anchors intended for use in concrete designed under the provisions of ACI 318. Criteria are prescribed to determine whether anchors ... -

Guide for Design and Construction with Autoclaved Aerated Concrete Panels
Abstract: Scope and objectives of this guide AAC, a form of cellular concrete, is a low-density cementitious product of calcium silicate hydrates in which the low density is obtained by the formation of macroscopic air bubbles, ... -
Superplasticizers and Other Chemical Admixtures in Concrete
Abstract: Preface In May 1978, the Canada Centre for Mineral and Energy Technology (CANMET), in association with the American Concrete Institute (ACI) sponsored a three-day conference in Ottawa, ON, Canada on the use of superplasticizers ... -
Shear in Structural Concrete
Abstract: INTRODUCTION This paper presents the results from an experimental program to investigate the effects of using Carbon Fiber Reinforced Polymer (CFRP) vertical strips epoxied to the webs of precast pretensioned I-girders. Vertical ... -
The 13th International Symposium on Fiber-Reinforced Polymer Reinforcement for Concrete Structures
Abstract: INTRODUCTION Application of wet lay-up Fiber reinforced polymer (FRP) systems in the repair industry is well accepted. These applications include structural strengthening of structures such as parking garages, buildings, ... -
Recent Advances in Concrete Technology and Sustainability Issues
Abstract: Preface The Canada Centre for Mineral and Energy Technology (CANMET) of Natural Resources of Canada, Ottawa, has played a significant role for more than 40 years in the broad area of concrete technology in Canada. In ... -
