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 acids; chloride ingress; carbonation; and freeze-thaw resistance. Fire resistance is also included; which is seldom considered; but is a very important aspect of the safety of the structure. Microstructure development and its relation to the durability properties of LWAC generally are not highlighted in the literature. The development of bonds; the microstructure with different binder systems; and different types of lightweight aggregates are explained. They show how lightweight aggregate concrete differs from normal weight concrete. The chapters on chloride ingress and freeze-thaw resistance are detailed because of the use of LWAC in offshore construction. The economical aspects of using LWAC are also reviewed. Emphasis is placed on the fact that although the cost of LWAC is high; the total cost of construction has to be considered; including the cost of transport; reinforcement; etc. When these are considered then LWAC becomes cheaper and attractive. The life cycle cost of the concrete is another consideration for calculating long-term savings on maintenance costs.

You are not going to find much in here about your favorite series or genre. Indeed.only a few are actually given mention. to emphasize Kelts narrative on the development of anime orthe supposed psychology behind that. It isnt that this is a poorly done work. Kelts monologue readseasily and is well constructed. As perhaps a necessary intro. he does provide a basic history of theemergence of the medium in the post-war era. and the key figures involved in that. Theres a good bitof theorizing on the effect on the Japanese psyche of the atomic bombings and the American occupation.Kelts also provides a look into the workings of the Japanese animation industry and its relations withUS business. He also engages in a somewhat involved look at the hentai(porn) market. in part toillustrate his emphasis on the sort of dual-nature lives Japanese live. with each individual keeping upan outer/public image that is detached from the inner/personal self. This idea forms one of themainstays of Kelts narrative. but somehow I doubt that every Japanese is perfectly comfortablewith the often gruesome imaginings expressed in manga/anime porn.The irony here(and supposedly the western sense of irony is a handicap) is that this book was published in2006. the year now regarded by many as the high-point of anime popularity in the US. after which themedium began to suffer a steady loss of the mainstream acceptance it had been attracting.Especially indicative of this are Kelts mention of upcoming Hollywood "blockbuster" adaptations ofvarious anime properties. none of which ever actually materialized.3 of 3 people found the following review helpful. superb discussion of Japan and the US. beyond anime and mangaBy Jazz fanAs an American who is fascinated with Japan. but frustrated with books about the relationship between the two countries. I found Roland Kelts "Japanamerica" to be a welcome breath of fresh air. Kelts focuses on the growing popularity of manga and anime among Americans. and the "mobius strip" of give and take between the two cultures. but his focus inevitably widens to address the broader mutual fascination between these two worlds. I love the fact that. as an American with a Japanese mother. Kelts avoids the two hazards of Japanophilia and Japanophobia. There is a refreshingly grounded and sensible middle ground in his analysis. a realism that seems to lighten things up and make it all more accessible and welcoming. Perhaps best of all - and this is a miracle in the world of cultural analysis - Kelts is delightfully unpretentious and his prose is as clear and comprehensible as it is filled with fascinating ideas and observations. Never for a moment do we doubt that Kelts knows what hes talking about it - and he brings it all across with infectious enthusiasm.0 of 0 people found the following review helpful. Anecdotes and a bit of dataBy ygnitionI used this for a term paper on the Cultural Invasion of Japanese themes to the west.It was interesting. but due to the nature of pop culture. it is a little out of date already. The internet obsoletes pop culture fast than sushi in a gas station on Miami.
