Title of the articleBitumen emulsions for waterproof and roof coverings
Abstract.bitumen emulsions are widely used in road construction. The main quality of bituminous emulsions is stability during storage and transportation: they should only break down while contacting with the surface. Anionic emulsions used in waterproofing of buildings and structures are less common due to their lower stability. The preparation of stable bitumen emulsions is impossible without the use of surfactants having necessary emulsifying and stabilizing properties. There are many chemical compounds that can be used to emulsify bitumen, but for technical and economic reasons, only a small number of them have become widespread. The aim of the study is to develop the composition of an aqueous emulsifier solution that ensures the stability of the bitumen emulsion and a high complex of properties of the binder obtained from it. To achieve the goal, the following tasks were solved: 1. Synthesis of an effective surfactant from the target domestic raw materials, which will ensure the consistency of composition and properties. 2. Determination of the selected surfactant influence on the properties of bituminous emulsions and binders obtained from these emulsions. Results. The main results of the study are to determine the optimal content of the surfactant, which will provide a high complex of properties of the emulsion and the binder obtained from it. Conclusions. The significance of the obtained results for the construction industry consists in increasing the storage stability of bitumen emulsions used for waterproofing buildings and structures.
Keywords.bitumen emulsion, oleic acid, liquid rubber, sprayed waterproofing, emulsifier
