Max Flo SP 804 is a superior grade napthalene based superplasticiser designed for high performance concrete mixes in extreme weather conditions.
ASTM C 494 Type B, D and G, BS EN 934-2
Max Flo SP 804 is specially recommended for concrete containing GGBS, fly ash, micro silica etc. and low water to binder ratios. It is used for pumpable concrete with greater time duration of slump retention requirements. It is extremely useful in concrete for piling, congested reinforcement, high rise towers, and mass concrete with temperature control for raft foundation, etc.
- Very high-water reduction capability.
- High grade concrete without excessive cement content.
- Superior slump retention even in hot climates without retardation.
- Controlled hydration for temperature monitored concrete.
- Increase durability by reducing permeability.
- Better pumpability
- Chloride free and safe for use in pre-stressed and reinforced concrete.

Typical results under laboratory conditions.
Results may vary as per site and usage conditions
Max Flo SP 804 can be used with all types of cements and cementitious materials like fly ash, GGBS, micro silica etc. Max Flo SP 804 should not be premixed with other admixtures unless recommended by Ressichem Technician.
Recommended dosage is 0.5 – 3 % by weight of cementitious material. Higher dosage can be used after verification by conducting lab and site trials. Optimum dosage of Max Flo SP 804 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.
Available in 1 Liter, 5 Liters, 10 Liters, 15 Liters, 30 Liters and 200 Liters of packaging.
Max Flo SP 804 should be directly dispensed into the concrete mixer together with mixing water.
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.
