Meet Fast-Track Schedules, Reduce Labor Requirements with Advanced Concrete Materials
Construction is a demanding business, made more challenging by worker shortages, rising costs, and increasing calls to fast-track projects. To meet these challenges, savvy contractors are relying on innovative concrete solutions to eliminate labor-intensive steps and accelerate turnaround times.
One of the greatest challenges for contractor G&C Concrete was finding the ideal solutions to improve productivity and accelerate placement of two floors of the high-rise each week. It needed concrete that would flow easily and self-consolidate around congested rebar in the walls and tapered columns, as well achieve rapid strength gain to remove the formwork of the floor slabs in a short amount of time.
Two innovative concrete products—Agileflow® and RAPIDFORCE®—proved to be the ideal solutions for meeting the demanding performance, speed of construction, and quality goals of the project.
The high-strength Agileflow self-consolidating concrete was developed to achieve the ideal flowability needed for speeding up pouring work on the heavily reinforced columns and walls without vibration. The mix also addressed the need for producing high-quality surfaces on each floor’s twenty-four perimeter columns to minimize labor-intensive finishing steps.
The contractor also relied on customized RAPIDFORCE high early-strength concrete for all sixty floors of the building. Designed with a blended cement containing silica fume and fly ash, these high-performance mixes consistently hit a rapid strength gain of 3,500 psi in only 24 hours for meeting the accelerated construction goals of each floor’s 11,500-square-foot slab.
