The remote field effect is an electromagnetic method for inspecting pipes and tubing. It has recently been commercialised as a technique for inspecting gray cast iron and ductile iron water mains. How-ever,commercial tools provide information on pits

Failures in cast iron water mains are more complex and diverse than is widely understood in the industry. This paper discusses the modes and causes of pipe failures that have been encountered during a three year investigation by the National Research

Structural insulated panels (SIPs) with skins of oriented strand boards (OSB) are increasingly used to build energy efficient dwellings. SIPs are sandwich-like construction products where stress-bearing facer panels are located on both sides of a cor

Structural insulated panels (SIPs) are a panelized building system composed of external oriented strand board (OSB) wood sheets bonded to a lightweight boardstock or pour-in-place foam core. This paper describes an investigation on the structural beh

Although the hydration of ordinary Portland cement (OPC) and its main constitutent, tricalcium silicate (3CaO.SiO2 or C3S), have been studied for many decades, some aspects of the hydration process remain poorly understood. In particular, there is li

This discussion comments on the recent model by Juilland and his co-authors for the dissolution of anhydrous cement in water and the induction period in cement hydration. A number of points where experimental data disagree with the model are describe

The decision to repair, renew, or replace existing old grey cast iron mains is typically based on performance indicators such as structural integrity, hydraulic efficiency, system reliability, and water quality. Structural integrity (often quantified

We report the results of magnetic measurements performed on specially prepared steel samples. These measurements were made after the samples had been uniaxially plastically deformed and the applied stress removed. The observed magnetic behaviour incl

The results of a metallographic study of gray cast-iron water pipes are reported. These pipes were installed between 1885 and 1973 in eight different water systems. Each pipe had been extracted during scheduled maintenance or failure repairs to provi
