Concrete TechnologyConcrete ConstructionCold Weather Concreting. Weather conditions at a jobsite – hot or cold, windy or calm, dry or humid – may be vastly different from the optimum conditions assumed at the time a concrete mix is specified, designed, or selected – or from laboratory conditions in which concrete specimens are stored and tested.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of ...
