It forms a rock hard, non-cracking matrix within minutes, with working times adjustable from a few minutes to 30 mins., enabling multiple concrete applications including quick return to service, all weather (hot, cold, wet) Portland concrete repair. EkoRok strongly self-bonds (eliminating "cold joint? problems), bonds exceptionally well to Portland concrete surfaces, achieves 3000 psi in 2 hrs. 5000 psi in 3-hours, 7000 psi in 24-hours and 10/12,000 psi in 28 days, non-corrosively bonds a wide variety of mineral, metal, cellulose aggregates, can be safely used indoors, outdoors (no out-gassing), is mold, moss and salt resistant, sets up underwater, withstands temperatures up to 2500C, doesn&＃39;t contain any toxins (including fly ash, thereby eliminating environmentally regulated concrete clean up problems), and can be conveniently produced and applied using conventional concrete technologies.
