SUPERPLASTYFIKATOR FM-2

usage:

Polycarboxylate based superplasticizer - designed to produce  ready-mix concrete, self compacting concrete (SCC) and high performance concrete (HPC).

Variant I  - ready-mix concrete
Dosage: 0,4-0,6 % by weight of cement. W/C ratio 0,4-0,45. Consistence: 10-12 cm in slump cone test (EN-12350-2:1999). Depending on the sort of concrete, allows to obtain stable concrete during 90 minutes and increases its compressive strenght.

Variant II  - Self compacting concrete (SCC)
Dosage: 1,0-1,2 %. W/C 0,4-0,5.The inverted slump cone should be 60 cm +/- 10%. Allows to obtain stable workability in 120 min +/- 10%. It should be pointed out that max granulation (in production SCC) should be 22 mm and value of fraction 0-0,125 in 1 m3 of concrete (including cement) should be 400-600 kg.

advantages:

    • maintain stable consistence in about 120 min +/-10 %
    • reduces amount of used cement, caused by great reduction of added water
    • in variant II reduces cost of construction (eliminates vibrating)
    • improve quality of concrete (glossy surface, great homogeneity, increase water and freeze resistance)
    • increase initial and final compressive strength
