Description

Phoscrete is an easy-to-use, fast-setting, long-lasting Magnesium-Alumina-Liquid-Phosphate (MALP) concrete repair material for repairs in extreme environments (-15°F to +115°F). Instead of water, Phoscrete’s pre-extended dry component mixes include Liquid Phosphate Activator (Freezing Point = -20°F). Working time and set time are easily controlled by supercooling the activator in hot temperatures, and by adding fast-set admixtures in cold temperatures. The presentation will include laboratory testing, field installation, and a small installation.

Objectives:

  1. Learn to control working time in any temperature using MALP concrete
  2. Observe examples of field work in both extremely hot and extremely cold environments
  3. Learn why the product was the material of choice for vertical and overhead repairs on a bridge over a large body of water, and how those repairs continued to be a success
  4. Observe the material mixed, placed and finished in the hot South Florida sun using supercooled activator and 85°F dry mix
