Overview

Improve the Quality of Concrete, Improve the Quality of Construction Quality measurement is not prevalent in the concrete industry and quality investment is not seen as potentially generating a positive return. Improving Concrete Quality examines how and why concrete quality should be measured, and includes instruction on developing specifications with the aim of improving concrete quality. Reduce Concrete Variability: Reduce Costs and Increase Volume The first part of the book considers the tangible and intangible benefits of improved quality. The later chapters explore concrete strength variability in detail. It provides a greater grasp of the variation in concrete, as well as a deeper understanding of how material variability affects concrete performance. The author discusses the components of variability (material, manufacturing, testing) and provides steps to measuring and reducing variability to improve the quality of concrete. The text also contains a chapter on data analysis for quality monitoring and test results. Come Away with Practices and Tools That Can Be Applied Immediately: Provides techniques and how specifications can improve concrete quality Offers a clear understanding of the link between the materials (cement, SCM, aggregate, water, air), manufacturing, testing variability, and concrete quality Includes information on analyzing test data to improve quality Improving Concrete Quality quantifies the benefits of improved quality, and introduces novel ways of measuring concrete quality. This text is an ideal resource for quality personnel in the concrete industry. It also benefits architects, engineers, contractors, and researchers.

Extremely comprehensive and practical... The chapter on basic statistics is a must read to clear the concepts required to understand how to analyse data for monitoring quality. Apart from the process - be it regarding material or testing, the author has also covered capability building and training which forms a core part of the entire business. -Indian Concrete Journal, December 2014 Many concrete manufacturers neglect to quantify not only the cost of producing poor quality concrete, but the potential savings in the reduction of cementitious content by focusing on standard deviation and tightening controls, particularly with regards to slump control and moisture contents - this book identifies key areas that manufacturers can focus on to improve and realize these savings. --Charl Marais, Aggregate Industries While there are many books on concrete technology, finding one that focuses strictly on improving concrete quality had been difficult until now. Improving Concrete Quality discusses how to improve performance, reduce time and costs, and lower the environmental footprint of concrete while also resulting in an overall improvement in the quality of concrete construction. -The Concrete Producer, September 2014
