A concrete must have: mobility of mixtures ?14 сm, durability at the compression in water one being no less than 40 МPа, a watertightness is no less W10, frost-resistance no less than 300 cycles, adgesy og a "new" concrete to "old" no less than 1,5 МPа. For the improvement of properties of concrete in its composition it is necessary to enter modifiers: Penetron А - tо 12 kg/m3; plasticizer S-3 - tо 4 kg/m3 and ground sand - to 48 kg/m3. For the rise of firmmess to the blows it is necessary to apply to 1,2 kg of polymeric fibre on m3 concrete Product Description popup.authors popup.nrat_date 2020-04-02 Close
