Abstract:
This month’s Q&A focuses on measuring F-numbers for slabs to receive a troweled finish in accordance with ASTM E1155-20, “Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers.” Specifically, on Note 3 of the standard recommending that all project participants agree on the exact test apparatus to be used for contract specification enforcement.

This month’s Q&A discusses the reinforcement stiffness ratio ρne that can be used for comparing the performance of various reinforcement types in slabs-on-ground and the design approach for glass fiber-reinforced polymer reinforcement in ACI/NEx MNL-6(23) based on percent reduction in unrestrained shrinkage strain from the enhanced aggregate interlock design of ACI PRC-360-10.

To reduce costs and minimize construction schedules for the recent light rail extension in the Phoenix, AZ, USA metropolitan area, track slabs and platform plinths were constructed using fiber-reinforced concrete instead of traditional steel-reinforced concrete. For every concrete placement, the use of fiber-reinforced concrete is estimated to have saved at least 1 to 2 days of labor.

This month’s Q&A focuses on issues related to meeting in-place concrete strength requirements for removing forms for reinforced concrete slabs. It explains how the contractor might accelerate the construction schedule by implementing concrete mixtures with compressive strengths exceeding those specified for the project.

Various reinforcement types can be evaluated to determine their relative performance in controlling the restrained shrinkage cracking behavior of concrete. Two sets of published test data on restrained shrinkage cracking of slabs-on-ground are analyzed, and a parameter suitable for comparing the performance of various reinforcement types is identified.
