Özet

The bleeding of concrete and the evaporation of water from the surface of concrete, which affect plastic shrinkage cracking, were investigated. The quantities of water evaporated from concrete specimens exposed to different temperatures, relative humidities and windy conditions were evaluated. The evaporation of water from the surface of C25 and C35 concretes, which were made using PKC/B 32.5R and PC 42.5 cements, was determined. It was observed that the cement type affects the bleeding of concrete. Also concrete mixes containing high cement contents yielded minimum quantities of bleeding. It was observed that concrete mixes containing more mixing water yielded the maximum amount of water evaporation. (C) 2003 Elsevier Ltd. All rights reserved.
