CARBON DIOXIDE UTILIZATION BY PRESSURIZED CONCRETE MIXER

Concrete production is one of the most power consuming processes in construction, which emits large amounts of CO2. The use of utilized carbon dioxide in concrete production can reduce the carbon trace of concrete production and therefore reduce its negative impact on the environment. The relevance of CO2 utilization in concrete production is due to several factors: 1. Environmental issues: Concrete production is one of the largest sources of carbon emissions. Therefore, the search for ways to reduce carbon emissions, including by CO2utilization, is relevant and obligatory. 2. Consumer Interest: An increasing number of consumers are oriented on environmentally friendly products and services, so the use of utilized CO2 in concrete production can increase the product attractiveness. 3. Starting the transition to a low carbon emitted economy: Due to growing global trendto carbon emission reduction, many countries and organizations are transiting to a low carbon emitted economy. New technologies such as the use of utilized CO2 in concrete production can contribute to this transition. The aim of research: the development of a pressurized concrete mixer. Object of research: concrete mixture with CO2. The article describes the design, principle of operation and schemes of a concrete mixer operating under pressure. This device was designed at the Almetyevsk State Institute in the laboratory of the Center for Scientific and Technical Research to conduct an experiment on concrete carbonization.
