In spite of the increasing use and demand for lightweight aggregate concrete (LWAC), there is still a lack of adequate explanations to understand the mechanisms responsible for the strength and durability properties of LWAC. This book is written to give an overall picture of LWAC, from the historical background, aggregate production, proportioning and production of concrete, to applications in structures. Physical properties and chemical durability are described in detail. The physical properties include density, strength, shrinkage, and elasticity. Chemical durability includes resistance to...

This broad-based, introductory reference provides excellent discussions regarding the hydration of Portland cement, durability problems in concrete, mechanisms of concrete deterioration, and interaction of polymers in concrete. It also covers properties of concrete with added polymers and practical applications of polymers in concrete. The historic background of polymers in building materials is examined, and a comprehensive comparison of natural vs. synthetic polymers is provided and conveniently summarized in a tabular format.

This collection of seminal essays, by one of the most eminent historians and educationists, provides a comprehensive view of medieval India. Satish Chandra explores four main themes-evolution of state, role of towns and urbanism, the historical and maritime traditions, and cultural pluralism.
Towards the end of the volume, Chandra surveys the role of leading Indian historians in promoting a more critical and secular view of medieval India. In a concluding historical assessment of the last fifty years, he highlights the role India could play in a challenging world order.

This book explores the complex linkages between state, society, and culture in medieval and modern India. It discusses issues like secularism, composite culture, pluralism, historiography, and the use of sources.
