When high-performance concrete for industrial floors is specified, the concrete must not only perform well in its hardened state, it also must possess certain plastic properties so contractors can properly place and finish it. Properties essential to high-quality HPC industrial floors include:
- A water-cementitious materials ratio of 0.45 to 0.50
- Minimum potential for cracking and curling
- Good to excellent abrasion resistance
- Measured flatness and levelness numbers of FF35/FL30 or higher
Article discusses how designers and contractors can achieve these qualities by using the proper plans, specifications and construction procedures.
