Research and Markets have included Elsevier Science and Technology¡¦s new report ¡§Lightweight Aggregate Concrete¡¨ to their cache.
Although the use of and demand for lightweight aggregate concrete (LWAC) are on an upward trajectory, the reasons behind the strength and long life of LWAC have no good explanations. The book provides a bird¡¦s eye view of LWAC, from its beginnings, aggregate production, proportioning and producing of concrete to its use in constructions. The physical attributes as well as chemical durability are elucidated in detail. Physical attributes touched upon are shrinkage, density, elasticity and strength. Chemical durability includes carbonation, freezeƒ{thaw resistance, chloride ingress and resistance to acids. Fire proofing is also taken into account although it is very rarely considered, although it is a very important safety aspect of construction.
Usually, literature does not draw attention to the microstructure development and its connection to the durability attribute of LWAC. The book, however, elucidates the microstructure of various binder systems, different kinds of lightweight aggregates and development of bonds. Explanations of how LWAC differs from normal weight concrete are provided. The chapters covering freezeƒ{thaw resistance and chloride ingress are detailed as LWAC is utilized in offshore constructions.
The financial repercussions of using LWAC are analysed. It has been underlined that although LWAC is expensive, the entire cost has to be taken into account such as cost of transportation, reinforcement, etc. When costs of various aspects are considered, LWAC becomes an economical and appealing option. The complete lifetime cost of concrete is another aspect to be taken into account in measuring long-term savings on sustenance costs.
