PIROLIZ MOYI ASOSIDA OLINGAN SUPERPLASTIFIKATORNI NEYTRALLASH JARAYONINI O’RGANISH

Аннотация

In this article, methods for obtaining new superplasticizers based on pyrolysis oil were developed, optimal conditions for the synthesis process were determined, their chemical structure and functional groups were studied using infrared spectroscopy (IR-spectroscopy), scanning electron microscopy (SEM) and thermogravimetric analysis (DTA). The effect of superplasticizers on aqueous mineral suspensions and cement-based composite systems was also studied. Pyrolysis oil, sulfuric acid, formalin, diethanolamine and sodium hydroxide were used as the main reagents. The structural structure, physicochemical and dispersion properties of the new superplasticizers, as well as their effect on the flowability and strength of concrete mixtures were determined and evaluated based on the laws of their concentration dependence. Keywords: pyrolysis oil, superplasticizer, concrete mix, plasticizer synthesis, physicochemical properties, IR spectroscopy, SEM (scanning electron microscopy), thermogravimetric analysis (DTA), naphthalene derivatives, local raw materials, organic additives, cement composition, dispersion properties.
