dcterms:description
In this project, we have tested and analyzed the effects of various commercially-used water repellents on the hydration process of Roman cement mortars. The effects on the pore size distribution and some physical features, such as water absorption and capillary rise, were investigated on Roman cement mortars treated with polymer-based coatings and inner waterproofing agents. The behavior of mortars in terms of their freeze resistance was also evaluated. The surface treatment using a hydrophobization agent completely prevented water absorption and thereby interrupted the hydration process. In the case of inner water-repellent admixtures, the hydration process progressed in spite of the decrease in water capillary transportation. In such circumstances, unimodal distribution of pore sizes was observed along with a decrease in threshold pore width with increased curing time.
