Development and Application of High-performance Self-compacting Fair-faced Finish Concrete under Complex Conditions Chun Gao1, 2 1.
For the mixture ratio test results first time, we must resolve the following issues: (1) Homogeneous problems of concrete, make it has good mobility without the risk of segregation
(1)Resistance to chloride ion permeability: The test results showed, electric fluxes of C50 self-compacting fair-faced finish concrete were less than 600C,and the smallest was only 426C, showed that resistance to chloride ion permeability of the concrete was good, and the concrete had a good durability.
Simulation pouring test on site Select the part of most intensive structural steel, in accordance with the 1:1 size, do simulated pouring test on work site to observe self-compacting properties of the physical model concrete, test the actual operating performance for large-scale production and application of self-compacting fare-faced finish concrete mixing station, guide organization of the raw materials, organization of production and construction, and test of concrete performance during the period of concrete production.

The chemical methods using benzalkonium chloride (Fig. 1 E) and water:ethanol 1:1 (v/v) are the least effective methods; in these surfaces, a lot of biological remains are observed on the granite.
The most characteristic peaks of the crust are those around 1200-1700 cm-1, assigned as ester groups (1200 cm-1), C-N functional group (1300 cm-1), C=C link (1500-1650 cm-1, also considered indicative of chromophores of chlorophyll following [17]), ester, aldehyde and ketone groups (1600 cm-1) and C-H group (2890 and 2920 cm-1).

The minimum ferrite grain size obtained by the new TMCP is less than 1µm.
In Japan, the study of this process started by Kudo [1] in 1974.
