Zhdanyuk K. Polymer modified mastics of high heat resistance for reinforced concrete highway bridge deck waterproofing.

Object - regularities of influence of polymer modified waterproofing mastics components on their structure and properties; purpose - raise of heat resistance of polymer modified waterproofing mastics; methods - standard, developed; novelty - increase of structure forming effect of spatial polymer network and phase inversion, when increasing polymer content in polymer modified matrix, that results in increase of parameters of heat resistance and elasticity, and decrease of flexibility temperature of mastics, has been determined; results - polymer modified mastic, containing 9 % of polymer, 20 % of kaolin, 1,25 % of polyacrylonitrile fiber and 10 % of plasticizer, provides high heat resistance (138 oС), flexibility (-30 oС) and water impermeability at 0.5 MPa of hydrostatic pressure; sphere of use - design, construction and reconstruction of reinforced concrete bridge decks.
