The drying shrinkage of concrete is analogous to the mechanism of drying of timber specimen. The loss of free water contained in hardened concrete, does not result in any appreciable dimension change. It is the loss of water held in gel pores that causes the change in the volume.
Floating and/or troweling operations following the. condensation of moisture from warm humid air on. cold concrete. In cold weather concrete sets slowly, in particular, cold concrete in basement floors. If. the humidity is relatively high, water will condense. on the freshly placed concrete, which, if troweled. into the surface, will cause dusting. d. Inadequate ventilation in enclosed spaces.
