Which class of concrete is often utilized for filler in steel grid floors?

Concrete used as filler in steel grid floors is typically classified as Class C concrete. Class C concrete is known for its lightweight properties and lower density, making it a suitable choice for applications that require reduced dead loads on structural supports. The use of Class C concrete in steel grid floors provides an effective balance between structural integrity and weight efficiency.

Additionally, Class C often provides adequate compressive strength while promoting ease of installation within the grid framework. This class is particularly advantageous in flooring systems because it can diminish the overall weight of the floor assembly, contributing to better performance under loading conditions and enhancing overall structural efficiency.
