Abstract:

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.

Abstract:

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.

Abstract:

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.

Abstract:

This article, the fourth in a five-part series on calculating deflections using a new expression for the effective moment of inertia Ie introduced into ACI CODE-318-19, provides a deflection example. The example follows the procedure outlined in Part 1 to compute the deflection of reinforced concrete (nonprestressed) one-way slab with both ends continuous.
