the panel weights for a concrete density of 2400 kg/m3 are given in Table 2. For heavily reinforced panels, the additional weight of the reinforcement may need to be considered to accurately determine the appropriate cranage. Panel Systems Concrete panels can be used either as cladding to the building, or as part of the loadbearing structure,

Curing Concrete, Chapter 12 - Memphis

Curing is the maintenance of a satisfactory moisture con-tent and temperature in concrete for a period of time imme-diately following placing and finishing so that the desired properties may develop (Fig. 12-1). The need for adequate curing of concrete cannot be overemphasized. Curing has a strong influence on the properties of hardened concrete;
