FIELD: production of building materials and hydrophobic compositions for hydroinsulation of construction structures and buildings. SUBSTANCE: material comprises hydrophobic agent and mineral filler. As hydrophobic agent, use is made of wastes collected by sewage purification facilities in gelatine producing enterprise, while as mineral filler, use is made of quartz sand mixed with finely dispersed mineral powder in weight ratio 1:(0.05-0.5). Said components are present in said material in the following weight ratio, wt.-%: hydrophobic agent, 0.5-1.5; mineral filler, 98.5-99.5. Proposed method increases hydrophobic effect by 35-50%, water permeability is reduced by one order of magnitude, and specific energy and labor input is reduced nearly twice. EFFECT: increased hydrophobic effect, reduced water permeability, and reduced specific energy and labor input. |
