Specifications
High early strength super highway repair materials
High early strength super highway repair materials is a pre-mixed powder material, which is based on white anti-crack fast set rapid hardening high belit sulphoaluminate cement, admixture of ploymer, set adjustment and strength enhance ect additve agent in proper proportion.
Technical index:
Setting time(min): subject to the requirment of customer
Compressive strength(mpa): 2h>=20, 28d>=50.0
Bending strength(mpa):2h>=5.0 ,28d>=7.5
Bonding strength(mpa):28d>=2.0
Size change ratio(%):28d,-0.05%~+0.05%
Water-solid ratio,W/P:0.15
Property:
1.low size change ratio. the free dry shrinkage ratio of white anti-crack fast set rapid hardening sulphoaluminate cement is only 1/10~1/8 to silicate cement, which made low size change rate of this kind of mortar. The long curing age of base concrete, large grain size of aggregate, low size change rate ect, which can efficiently prevent the cracking of concrete.
2.high early strength: 2h compressive strength can reach above 20.0mpa, 28d compressive strength above 50mpa can meet the requirment of urgent repair and large foundation load; higher bond strength:>=20.0mpa,which can combine the repair mortar with concrete base and bear the common strong load.
3.With two double expansion of swelling and hardening plastic,the mortar is compact and anti-freeze, high impermeability function.
4. anti-corrosion
