XPERT 450 GP
Concrete Admixture
XPERT 450 GP
Variable Dosage “General Purpose” Admixture for Concrete
XPERT 450 GP is a new generation mid-range water-reducing admixture formulated to increase water reduction and compressive strengths and enhance finish ability. Normal concrete set ting characteristics are obtained at recommended dosage range. XPERT 450 GP is especially effective in lean concretes and/or concretes containing such pozzolanic materials as fly ash, silica fume and slag. XPERT 450 GP produces concrete with a lower unit water content resulting in more impermeable and durable concrete.
BENEFITS
• Water Reduction: Type A @ 0.4-0.44 w/c
• Superior finishing characteristics.
• Easier and faster pumping of concrete.
• Reduced concrete shrinkage and cracking.
• Increased compressive and flexural strengths.
• Greater concrete impermeability and durability.
• Extended slump retention.
• Improved appearance of architectural concrete.
RECOMMENDATIONS
XPERT 450 GP is especially effective in lean concretes and/or concretes containing such pozzolanic materials as fly ash, silica fume and slag. XPERT 450 GP produces concrete with a lower unit water content resulting in more impermeable and durable concrete.
DOSAGE
The recommended dosage range for XPERT 450 GP 400 to 1000 ml per 100 Kg of cement as an ASTM C-494 Type A admixture. If fast water reduction is required, dosage rates up to 1200 ml per 100 kgs of cementitious may be used; however, it is recommended that trial mixes be conducted to determine the required dosage for optimum performance with your concrete components.
