Introduction Water quenched blast furnace slag (GBFS) is main cementitious material of NSC, it accounts for 80%-90% of non-clinker slag cement.
Experimental methods raw materials and mixing ratio.Main component of cementitious materials is GMFS and phosphorus gypsum which alkalinity is greater than 4.5, vitrification-ratio is greater than 98.5%.
Mineral composition of raw materials and physical property follows in Table 1.
NSC’s bleeding-water phenomenon slightly larger than the OPC, it caused by early hydration rate is relatively slows than OPC.Excessive bleeding-water may lead to the material layered segregation, it not only affect the concrete’s early strength and long-term strength, but also directly affect the long-term durability of the structure.

Titanium alloy TC4 is a kind of α + β alloy, certain characteristics, however, such as low thermal conductivity, strong chemical reactivity with the cutting tool materials at high temperatures, and relatively low elastic modulus, make it one of the classical difficult-to-cut materials[3].
This is mainly because of big brittleness and high hardness of the CBN cutting tool material itself, and the micro defects of materials inside.
