Recently, prefabricated building processes have been enhanced by advances in design, information technologies, and machineries as well as the current emphasis within the industry to reduce waste materials, energy consumption, labor requirements, project duration, and costs.
Preassembly is “a process by which various materials, prefabricated components, and/or equipment are joined together at a remote location for subsequent installation as a unit” [14].

Test materials Using P.O 42.5 ordinary Portland cement and P.S.A 32.5 slag cement; Tianjin Baoming Limited Company’s production of CSA concrete expansive agent and Huainan Datong manufacturer’s production of D-accelerating agent.
Slag cement has low content of clinker, the hydration speed of mixing materials is slow at normal temperature, so the coagulation time is long and the intension is low in the early period.
Fig.3 The XRD pattern of slag cement Fig.4 The XRD pattern of portland cement Composite cementitious materials composite cementitious materials Test of mixing ratio “Technical Specifications for Structural Strengthening with Sprayed Concrete” requires us to make the steel fiber volume ratio of 1.0%-1.5% in steel fiber reinforced shotcrete.

Material Model.
The material model of MAT_PLASTIC_KINEMATIC was selected to be reinforcing steel bars of pier in this paper, which was an isotropic material model associated with strain rate.
In a general way, in the nonlinear analysis of reinforced concrete structures, elastic-plastic mode was used to be the material of steel bars, that is when the material is in the plastic state, its stress remained constant, while the strain increasing.

Its composition is complicated and most of the harmful materials are the fine particulate matters.
Its main intergradient is sulfates, nitrates, ammonium salt, carbonaceous articles, heavy metals and crustal materials.
While the micro subject has to make a decision between the economic indicator and the ecological civilization indicator, the public must choose between material life level and environmental quality.

Study on Cumulate Function of Cut-In Impacting Disrepair with Waved-Edge Milling Insert WANG Zhigang1, a, WEI Hualigang2, b, LI Zhenjia 1, c and CAI Dongsong1, d 1 Mechanical Engineering Department of Harbin University of Science and Technology, P.O.Box 92, 150080, China 2 Harbin Measuring & Cutting Tool Group Co.
So in order to save blade, workpiece material and time, on the premise that disrepair ruler was already known, the small sample of 10 blades was chosen.
