Abstract:
Due to the development of powerful high-range water-reducing admixtures and viscosity modifying admixtures, it is now possible to very efficiently and economically build high-rise concrete structures. These admixtures allow concrete to be pumped from the first to the highest floor, so it is no longer necessary to use cranes to transport and place concrete. This article shows how the construction of high-rise buildings has evolved from entirely structural steel structures to almost exclusively reinforced concrete structures, by discussing the construction of some landmark structures built from 1968 to the present.
