Chemistry of Cement & Concreteby F. M. Lea
Synopses & Reviews
THE CHEMISTRY OF CEMENT AND CONCRETE, Third Edition F.M LEA The advances in the chemistry and physics of cements led to the necessity for this third edition. Lea's book deals with the chemical and physical properties of cements and concretes and their relation to the practical problems that arise in their manufacture and use. It will be of great interest not only to the chemist involved in the science and technology of silicate materials but also to those using concrete in building and civil engineering construction. Attention is given to problems arising in the use of concrete, from the suitability of materials, to the conditions under which concrete may deteriorate and the precautionary or remedial measures that can be adopted. It is well illustrated with line drawings, tables and photographs. PARTIAL CONTENTS: History of calcareous cements; Classification of cements; Portland cements: Raw materials and manufacturing processes; Cement components and their phase relations; Cementing qualities of the cement compounds; Constitution, burning, proportioning, hydration and setting and hardening of Portland cement; Structure of cement compounds; Action of acid and sulphate waters of Portland Cement; Physical and mechanical properties of Portland Cement, Pozzolanas and Pozzolanic cements; Cements made from blast furnace slag; High Alumina cement, some special cements and cement properties; Concrete aggregates; Resistance of Concrete to various organic and inorganic agents; Examination of concrete failures.
