STUDY OF AN ORGANIC COMPOUND WITH SULFUR AS A MODIFIER FOR INNOVATIVE CONCRETE
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 11
Abstract
The article investigated the kinetics of modified sulfur samples using thermogravimetric analysis methods. New innovative concrete, modified with organic compounds, and its physicochemical properties were studied. This innovative concrete was produced using a sulfur-modifier modification and a number of components. Thermogravimetric analysis (TG) of the modifier was carried out to study its response to heat treatment. TG analysis was performed using Thermo Scientific GC1310 in combination with Tsq 9000\_TA Instruments STD 650 (USA). The temperature range of analysis was set within 100-1000°C. Thermal expansion coefficient of the studied sulfur-containing concrete. The results also confirmed that the coefficient of thermal expansion for concrete modified with sulfur modifier was 14.8×10 -6/0 C. The average deformation of the analyzed concrete was 0.0026-0.0051, which indicates excellent deformation characteristics compared to conventional concrete The sulfur-modifier modification experiences a one-stage thermal mass loss, and the mass loss phenomena are endothermic in nature.
