| The paper explores the possibility of applying the nanopolymer trietoxiisobutylsilane and methyl silicon resin for hydrophobisation of mortars with the lightweight aggregate addition (PVC + PUR + WD). The investigation involved the mortars with two types of hydrophobic agents, without and with waste addition (5; 10; 15%). The results and discussion referring to their micro-structure together with the interfacial transition zone (ITZ). Physical and mechanical properties, frost resistance, water absorption, as well as vapor permeability were investigated. The influence of hydrophobisation on the SFE value, CA and microroughness characteristic was also determined. The surface hydrophobisation of mortars using the A1 preparation reduced the water absorption and vapour permeability by 94.6%. The A1 agent reduced the weight loss after the F-T test by 88.9%. Surface hydrophobisation increased the CA value, and reduced the SFE value for the L5 and L10 mortars by over 3 times. The greatest effect on the decrease of A2 preparation roughness was proven. The efficiency of both agents was confirmed by the capillary uptake test conducted using the TDR equipment. |
