Impact of Slag Powder Concent on Splitting Tensile Properties of Concrete Zhangxiao Na1, a, Liuqin2,b 1,,2Huang He Science and Technology University, Zhengzhou, Henan, 450063, China a45165920@qq.com, b32090881@qq.com, Keywords: Slag Powder; Experimental Study; Age; Water-cement Ratio; Splitting Tensile Strength.
Test Overview Test Program Test uses ordinary portland cement, physical and mechanical properties of 42.5 is showed in Table 1 below,including 5 ~ 10 mm diameter gravel (30%), 10 ~ 20 mm diameter gravel (40%), 20 ~ 30 mm diameter gravel accounted for 30%.
With the speed of 0.04~0.06Mpa/s continuous and uniform loading, until the specimen splitting failure, record breaking load.The test loading is shown in figure 1.
Fig. 1 The force digram of splitting tensile specimen Specimen Failure Modes The splitting failure of the concrete test is pure cleavage cracking along the axis , split on the surface of the stone directly was pulled off, rather than around the stone damage.

The designing process includes a comprehensive set of [1]: · Material relations (machines, equipment), · Human relations, · Time-related relations (optimization of works on the project, optimization of implementation) .
In general we can classify the designing as follows: [1]: · Set up (arrangement) of the time structure · Set up (arrangement) of the spatial structure The result of the time-line designing is a design of the production organization with proposed information and control systems.

The contour plots for stress results of two typical groups (No. 2-1 and No. 8-1) are shown in Fig. 3.
