INFLUENCE OF SURFACTANTS - “L. O. C.” ON THE PROPERTIES OF THE COMPOSITE CONCRETE BASED MATERIAL
The paper considers the influence of the surfactant “L. O. C.” on the performance characteristics of a composite material based on concrete, in order to establish its effectiveness as a modifier. Samples of building concrete modified by the developed multifunctional cleaning agent - L. O. C. were made, samples were tested for workability and compressive strength of concrete, taking into account the age of the sample and the dosage of the multifunctional cleaning agent in it,% of the mass of cement. The results of the tests carried out showed that modified with a multifunctional cleaner - “L. O. C.” samples of composite material have the best operational characteristics. The optimal dosage of the developed chemical additive has been established. The main advantage of such chemical additives is their multifunctionality of action, environmental friendliness and small dosages, which guarantee economic feasibility.
