STANDARD
ASTM C 494 Type B, D and G, BS EN 934-2
USES
Max Flo SP 805 is specially recommended for concrete with low water-cement ratios and containing pozzolanic materials. It helps in producing easily pumpable concrete with triple blend and double blend mixes. It is used in concrete for piling, mass concrete for raft foundations, high-rise towers, and concrete in hot weather conditions, etc.
ADVANTAGES
Very high-water reduction capability > 30%.
Allows production of high-grade concrete without excessive cement content.
Increases durability by reducing permeability.
Excellent slump retention even in hot climates.
Controlled hydration for temperature-monitored concrete.
Better pumpability.
Chloride-free and safe for use in pre-stressed and reinforced concrete.

COMPATIBILITY
Max Flo SP 805 can be used with all types of cements and cementitious materials like fly ash, GGBS, and micro silica. Max Flo SP 805 should not be premixed with other admixtures unless recommended by a Ressichem technician.
DOSAGE
Recommended dosage is 1.0 – 2.5 % by weight of cementitious material. Higher dosage can be used after verification by conducting lab and site trials. Optimum dosage of Max Flo SP 805 and effect on concrete properties such as workability, strength, setting time, etc. are best assessed after preliminary tests on site using the actual materials of mixes under consideration.
EFFECT OF OVERDOSING
Overdosing may result in higher workability and delay in setting. If intentionally or accidentally, dosage used is above the recommended dosages, care must be taken to allow for the effect on the stripping time of formwork. In such cases, provided the concrete is properly cured, the ultimate strength will generally be higher than the regular concrete. The effects of overdosing are increased when sulphate resistant cement is used in the concrete mixes because of the chemical nature of the cement as compared to that of OPC.
PACK SIZE
Available in 1 Liter, 5 Liters, 10 Liters, 15 Liters, 30 Liters, and 200 Liters of packaging.
DISPENSING
Max Flo SP 805 should be directly dispensed into the concrete mixer together with the mixing water.
SHELF LIFE
12 months from the date of manufacture when stored under cool and dry warehouse conditions in original unopened packaging. Extreme temperature and humidity may reduce shelf life.
