| Abstract: | The effects of the different content of water-cement ratio,micro-slag power,admixture on the dry-mixed mortar are studied according to orthogonal experiment.The results showed that it has the characteristics of high fluidity and high strength with 8 percent of micro-slag power.The compressive strength of 1 d is up to 30 MPa.And its fluidity is up to 250 mm.It has no bleeding phenomenon.Therefore the super-high mortar studied is mainly used for casting reinforcement and rush repairing engineering.It has grea... |
