Thermal Changes in the Mass, Size and Density of Steel Fiber Concrete after Calefaction

Abstract:

This report outlines the results of an experimental study conducted on the effects high temperatures have on changes in linear sizes, mass, and density of steel fiber concrete containing fiber with varying durability, types, diameter, and percentages by volume. After being exposed to heat, the steel fiber concrete reduces in linear size, as well as decreasing in mass and density. Changes are seen as a result of rising temperatures between 20-1100 °С The impact on the change in mass, size and density of the quantity and type of fiber is not unambiguous, it does not fully correspond to the theoretical concepts considered in the work and require additional research.
