Preparation of Sodium Silicate Fluid Grouts and Investigation of Their Influence on the Thermal Stability of Slag-Lime Concrete

详细

The results of investigating the effect of liquid glass fluid grouts based on rotten stone (tripoli) on the basic properties of slag-lime heat resistant concrete are given, with titanium magnetite refinement tailings being used as the aggregate. The influence of three types of slag cement-based fluid grouts was analyzed. The residual strength of the concrete (after exposure at 800°C) exceeds the initial strength, the thermal stability of the concrete samples depending on the type of fluid grout reaches 32 water thermal cycles. The results of the study show that the heat-resistant slag-lime concrete based on liquid glass and titanium magnetite refinement tailings are promising for practical application.
