DESIGN EVOLUTION OF P DESIGN EVOLUTION OF PRECAST SANDWICH PANEL UHP–FRC Precast Sandwich Panel
Standard Precast Sandwich Panel Prototype I is industry standard for a pre-cast sandwich panel. In collaboration with Gate Pre-cast and Thermomass, a typical noncomposite assembly is chosen to cast a 3’x3’ panel. The assembly consists of a 3” facing wythe, 2” EPS rigid insulation, and a 3” structural backing wythe. Each wythe is structurally reinforced with 6”x6” wire mesh for cracking resistance attached to #4 (1/2”) re-bar around the parameter and through the ferrule loop inserts for tensile reinforcement.
Phase I Phase II Phase III Prototype II establishes a UHP–
Phase I
FRC sandwich panel baseline comparable to the industry standard panel. Given the enhanced compressive strength of UHP–FRC a comparable noncomposite assembly is made. The cast is a 3’x3’ panel consisting of a 1-1/2” facing wythe, 2” EPS rigid insulation, and a 1-1/2” structural backing wythe. The Thermomass CC–130 ties between the wythes extend 1-1/2” from the insulation were cut down on each end to avoid protrusion through the face.
