Comparative Analysis of the Water Resistance of Restoration Solutions
Abstract: The paper considers the properties of lime-cement composites with the introduction of filler. Indicators of normal density, separability and water retention capacity are given. From the research results it follows that the introduction of filler can increase the degree of filling of cement stone and optimize the saturation of cement stone with filler, which reduces water demand and increase strength compared to cement-lime composition. For stucco lime mixtures, it is optimal to reduce the consumption of lime by 40…50 % with the introduction of filler in the amount of 80 % of the replaced mass of lime. Cemented stucco mortars with a filler have lower water absorption and a lower drop in strength in a water-saturated state by 20…25 % in comparison with cement-lime mortar, which increases frost resistance up to 15 %.
Keywords: restoration mortars, cement-lime mortar, adhesion.
