Reviews reported maturity-strength relationships and describes a file developed with spreadsheet software to relate maturity-strength data with slab capacity. Other developed spreadsheet files are described that determine required slab capacities for shored floor construction and use maturity-capacity relationships with anticipated curing temperatures to define project curing activities and corresponding durations. Project scheduling software is used to provide generalized shored floor construction logistics. ASCII files, created with spreadsheet software, import estimated curing time requirements for different anticipated curing histories. Project software can quickly incorporate the imported file information into the project schedule to benefit contractors by improving the accuracy of the project schedule and cost.
