BP-MegaFlow P4

BP-Megaflow P4 is a water-reducing and set retarding concete admixture in brown liquid form
which is BP-Megaflow P4 is a effective, water reducing, plasticiser and an extremely powerful deflocculating
agent. It is based on polymeric sulphonate napthalene. It makes concrete cohesive and minimizes segregation and bleeding. BPMegaflow P4 waterproofs by improving the quality of the concrete or mortar. It reduces the water demand for required workability of concrete.


ASTM C494, Type A, B and D, BSEN 934-2

Application Area

BP-Megaflow P4 is used to produce easily workable and dense concrete for all types of ready-mixed concrete, tunnels, runways, canals, reservoirs and marine structures, etc. It can also be used as waterproofer to reduce permeability of concrete.


✓ Good slump retention even at higher temperature.
✓ Good workability improvement to most of concrete mixes.
✓ 10-15% water reducing effect can be obtained.
✓ Increases strength due to water reduction.
✓ Pumpable concrete.
✓ Effective in achieving cement reduction.
✓ Durable concrete may be achieved.
✓ Extended setting time at high temperatures.
✓ Reduced shrinkage and creep.


BP-Megaflow P4 can be used with all types of cements and cementitious materials like fly ash, GGBS, micro silica,etc. MegaFlow P4 should not be premixed with other admixtures.


Recommended dosage is 0.5 – 1.5% by weight of cementitious material. Higher dosage can be used after verification by conducting lab and site trials. Optimum dosage of BP-Megaflow P4 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. verdosing may result in higher workability and fast setting. If intentionally or Effect of overdosing accidentally increased above the commended limit, ensure that the stripping time of formwork is extended
