Aaro Happonen investigated drying of six different concretes containing blast furnace slag in his master\u2019s thesis: \u201cDrying of low-carbon concrete\u201d. In the research relative humidity measurements were conducted in a period of 180 days for one-sided drying samples, sealed samples and samples that were wetted for a 30-day period starting 60 days after cast. Moisture transport properties of concretes were estimated using mass change measurements and computational methods.<\/p>\n\n\n\n<p>Based on results of research, drying mechanisms of slag concretes seem to differ from ordinary concretes. Slag concretes dried faster due to chemical reaction than ordinary concretes. Moisture transport properties of slag concretes were measured to be significantly lower than those of ordinary concretes. Slag concretes with low water to binder ratio seem to suit well to structures that require fast drying. On the other hand, drying properties of high w\/b slag concretes seem to be limited. Moisture control of worksites is increasingly important with slag concrete casts as delays for drying are even longer than with ordinary concretes.<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/betoni.com\/lehti\/2023\/10\/06\/vahahiilisen-betonin-kuivuminen\/\">Read the entire article in Finnish and see the images &gt;&gt;<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Increasing use of blast furnace slag concretes creates a need to be more aware of their properties.
