In order to study the effects of finely ground aggregates on the various properties of portland cement-lime (PCL), mortars a research study was conducted. The purpose of this project was to evaluate the effects these materials had on the plastic and hardened properties of (PCL) mortars. Tests conducted on cement-lime mortars suggest that inclusion of finely ground aggregates mixed with the lime used in PCL mortars, produced some beneficial and no detrimental effects on the mortar properties. The air content of the mortars remained approximately the same over the range of replacement types and percentages evaluated, and the water retention values increased with increased percentages of finely ground aggregate materials. Furthermore, while the compressive strength of the mortars showed a slight decrease with increased fine materials at 7 days the compression strength at 28 days increased slightly. In addition, the flexural bond strength of the mortar showed a trend in increased flexural strength with additions of fine aggregate materials, although the high variation in the results showed a very low correlation factor.

Estimating, modelling, controlling and monitoring the flow of concrete is a vital part of the construction process, as the properties of concrete before it has set can have a significant impact on performance. This book provides a detailed overview of the rheological behaviour of concrete, including measurement techniques, the impact of mix design, and casting. Part one begins with two introductory chapters dealing with the rheology and rheometry of complex fluids, followed by chapters that examine specific measurement and testing techniques for concrete. The focus of part two is the impact of mix design on the rheological behaviour of concrete, looking at additives including superplasticizers and viscosity agents. Finally, chapters in part three cover topics related to casting, such as thixotropy and formwork pressure. With its distinguished editor and expert team of contributors, Understanding the rheology of concrete is an essential reference for researchers, materials specifiers, architects and designers in any section of the construction industry that makes use of concrete, and will also benefit graduate and undergraduate students of civil engineering, materials and construction. Provides a detailed overview of the rheological behaviour of concrete, including measurement techniques, casting and the impact of mix design The estimating, modelling, controlling and monitoring of concrete flow is comprehensively discussed Chapters examine specific measurement and testing techniques for concrete, the impact of mix design on the rheological behaviour of concrete, particle packaging and viscosity-enhancing admixtures

Over three billion metric tons of cement are produced annually worldwide, making concrete the most extensively used construction material. Self-sensing, or smart, cement allows real-time monitoring of performance through the entire service life of a concrete structure, for the detection of changing stresses, contamination, excessive temperature, gas leaks and pre-seismic activity. This is achieved by adding a very small proportion of conductive or semi-conductive fibers, such as carbon fibers to the bulk cement, making it piezoresistive, and enabling changes in the concrete’s electrical resistivity in response to shear stress and strain to be monitored. This state-of-the-art reference work presents experimental results with a realistic theoretical framework, for cement manufactures, concrete technologists and contractors as well as researchers.

This book presents a state of the art in mortar characterisation, experimentation with and applications of new mortars for conservation and repair of historic buildings. This volume includes the following topics: characterisation of historic mortars (methods, interpretation, application of results), development of new materials for conservation (compatibility, durability, mix designs), the history of mortar technology and fundamental experimental studies of material properties. The papers have been selected from those presented at the 3rd Historic Mortars Conference, held in Glasgow, Scotland, September 11-14th 2013. All the papers here underwent a two stage peer review process, for the conference and again for this volume. In some cases this has resulted in a revision and updating of content.
