DESCRIPTION OF WATER RESISTANT GYPSUM-CONTAINING COMPOSITION WITH A COMBINED CRITERIA
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 168, Issue 2
Abstract
This article discusses the characteristics of the water resistance of composite materials based on gypsum-cement-ash binders. The example of the relationship of strength characteristics demonstrates that the classical softening coefficient is not enough proper evaluation of its water resistance. A more objective and accurate description - the index of water resistance Кв, having the character of the corrected strength, is proposed. It has been shown that water resistance index correlates with the strength characteristics much better than the softening coefficient. Authors consider the advantages of the proposed characteristics over existing and generalization of proposed approach to other characteristics of the material. Water resistance index can be used as an optimality criterion in materials science problems.
