The Usage of Loose Moisture Capable Materials in Concrete Technology
Incoming article date: 05.12.2016The high water demand of high-plastic and mushy consistency of concrete with high value of water-to-cement ratio leads to decreasing of consistency value and strength of concrete and also to shrinkage of concrete increasing. The known ways of excess water removal from the mix of concrete ingredients with water are labor-consuming and not always effective enough. We suggest the way of excess water removal using loose moisture capable materials which are enabled to absorb water intensively when contacting the concrete mix. The capacity of powder-like materials to absorb water can be evaluated with maximum molecular moisture capacity and maximum capillary moisture capacity measurement units. Also the criterion of water absorbing capacity of powders is suggested, and the most effective loose moisture capable material between others is defined.
