MA.P.E./Cr 05 … “The Liquid Revolution”
DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … - Characteristics • White Liquid Product • Based on Antimony Trioxide • Liquid suspension • Two versions available: • MA.P.E./Cr 05 LV (Low Viscosity) – for normal use • MA.P.E./Cr 05 AF (Anti Freeze) – for cold environments (up to -15°C)
DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … - Advantages • Reduced Costs, similar to Iron salts • Very long lasting Cr(VI) reduction, 1 year • Easy to use, dosing requires a pump only • Low and stoichiometric dosage, no waste material • Neutral pH (No ADR) • Patented Technology, result of Mapei expertise and R&D
DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … – How does it work? • Cr(VI) reduction with MA.P.E./Cr 05 … can be explained in four steps: • Dosing MA.P.E./Cr 05 …; • Cement grinding; • Cement storage; • Cement hydration and Cr(VI) reduction.
Raw Material Cement Mill Cement Silos End User DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … – How does it work? • Step 1: Dosing MA.P.E./Cr 05 …: • It is recommended to dose directly on the clinker conveyor; • Indicative dosage: 50 g / ppm Cr(VI) / ton cement.
Raw Material Cement Mill Cement Silos End User DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … – How does it work? • Step 2: Cement Grinding: • MA.P.E./Cr 05 … must be ground with the cement in order to break down the suspension and mix it into the cement.
Raw Material Cement Mill Cement Silos End User DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … – How does it work? • Step 3: Cement Storage: • MA.P.E./Cr 05 … does not suffer heat or humidity; it remains “asleep” inside the cement.
Raw Material Cement Mill Cement Silos End User DAM - Cement Grinding Aids Division MA.P.E./Cr 05 … – How does it work? • Step 4: Cement Hydration and Cr(VI) reduction: • Once the cement is hydrated (pH rises > 12, Cr(VI) is released), MA.P.E./Cr 05 … becomes soluble and reduces Cr(VI).
