Ulti-Grout is a rapid hardening, sulfate resistant, general purpose grout that is easily mixed for grouting at various consistencies, allowing flexibility in the methodology of reinserting cores. This rapid hardening material utilizes Qwix, a hydraulic, cementitious mineral blend (ASTM C219), high in calcium sulfate aluminum crystals. Qwix blended with portland cement produces a modified type of Portland cement called Ultimax Cement. Ultimax Cement is a patented formula for a blended, hydraulic, non-shrink, high performance cement that exceeds the requirements of ASTM C-1157. Ulti-Grout develops strength faster than Portland-based grouts by a factor of 50 to 1. Flowability and self-leveling consistency of Ulti-Grout requires no placing in lifts or consolidating by mechanical means. The rapid hardening properties of Ulti-Grout allows for earlier, higher load carrying capability so roadways can be opened to traffic within one hour of placement. Ulti-Grout can be formulated to meet a wide variety of project specific performance requirements including strength, set time, flow and thermal properties. 610.882.5000,
