Concrete technology has developed rapidly over the past few decades, and more and more high-performance concretes are now available on the market. Amongthem, ultra-high performance concrete (UHPC) is well known for its high mechanical strength and material durability.
Concrete technologies utilize lightweight, high-performance, high-strength, shotcrete, and under water concrete, and may also require special admixtures called viscosity improvers.
About the Book
Concrete is the most versatile building material. Its ability to be easily formed into any shape makes it widely used in infrastructure projects such as buildings, bridges, dams, silos, and pavements. The durability of these structures depends on the quality of concrete production, testing, and maintenance.
This book is intended to provide students and professionals with an in-depth understanding of concrete technology. It describes the basic concepts of concrete and its components, material properties, and related laboratory experiments. It also includes relevant provisions of Indian Standards such as IS 456, IS 10262, IS 383, IS 2386 and IS 516.
Unit I details the properties of the components of concrete i.e. cement, aggregate and water. Unit II describes the various grades of concrete and properties of fresh concrete. Unit III outlines the procedure for concrete mix design as per IS 10262. Destructive and non-destructive testing of hardened concrete will also be discussed.
Unit IV details the quality control in various concrete operations. Form work for concrete placement, water proofing, and seams in concrete construction will also be discussed in detail. Unit V discusses chemical admixtures, special concrete, and placing concrete in extreme weather conditions. Unit VI details laboratory and field experiments to determine the properties of concrete and its components.
This book provides the latest scientific advances in concrete technology. It is hoped that students will find this book easy to follow and that the entire concrete technology community will benefit from it.
