RISCarbonation and pH in Mortars Manufactured with Supplementary Cementitious Materials
Publisher: American Society of Civil Engineers
Abstract: An investigation of carbonation in mortars and methods of measuring the degree of carbonation and pH change is presented. The mortars were manufactured using ordinary portland cement, pulverized fuel ash, ground granulated ...
Repeatability and Reliability of New Air and Water Permeability Tests for Assessing the Durability of High-Performance Concretes
Publisher: American Society of Civil Engineers
Abstract: This paper reports on the accuracy of new test methods developed to measure the air and water permeability of high-performance concretes (HPCs). Five representative HPC and one normal concrete (NC) mixtures were tested to ...
The Q.U.B. Axisymmetric and Multi-Resonant Wave Energy Convertors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the optimization of the power conversion chain and the engineering design considerations of an oscillating water column wave power device which would form part of a 2-GW ...
New Test Method to Obtain pH Profiles due to Carbonation of Concretes Containing Supplementary Cementitious Materials
Publisher: American Society of Civil Engineers
Abstract: The writers have carried out an investigation to develop apparent pH profiles of concretes for a variety of cement blends viz. normal portland cement containing by mass 30% pulverized fuel ash, 50% ground granulated ...
