Best Practices for Concrete Pavements / Supplementary Cementitious Materials Tech brief
Hydraulic activity refers to a property most familiar when discussing hydraulic cement such as ordinary portland cement (OPC). ASTM C125-15a defines hydraulic cement as “a cement that sets and hardens by chemical reaction with water and is capable of doing so under water.” That is, hydraulic cements, including SCMs that have hydraulic properties, react with water to harden, and that hardening p...
متن کاملFRP Dowels for Concrete Pavements
A Paper for the World Wise Conference 1999 Winnipeg, Manitoba © November 15, 1999 Introduction Joints are used in concrete pavements in order to control cracking due to thermal and environmental conditions. Dowels span joints to transfer load from one slab to an adjacent slab and to provide vertical and horizontal alignment. Currently, smooth epoxy coated steel dowels are placed across transver...
متن کاملThe Influence of Ultrafine Filler Materials on Mechanical and Durability Characteristics of Concrete
This paper aims at investigating the influence of partial replacement of Portland cement with ultrafine fillers compared to limestone powder on the durability and mechanical characteristics of concrete. For this purpose, ultrafine calcium carbonate materials with different specific surface areas of 9.7 and 15.1 m2/g and limestone powder (0.72 m2/g) were used. The results indicate that the ultra...
متن کاملUltrasonic Tomography Technique for Evaluation Concrete Pavements
Ultrasonic tomography is an emerging technology that shows promise for quality assurance/quality control (QA/QC) during construction, or for making rehabilitation decisions in concrete pavements. However, the benefits of this emerging technology have not yet been fully captured for widespread use in highway infrastructure management. Verification of a state-of-the-art ultrasonic tomography devi...
