Abstract:

Use concrete pressure testing machine to test the properties of Cement slurry , and conduct the ASTMC1202 penetration test of the properties and MIP which test the properties and microstructure characteristics. Base on the analysis of the relationship of cement strength and permeability, microstructural features. The results show that, with the increase of the permeability of cement slurry net of intensity decreased by 13%; The increase of pore volume total 11%, and the average pore volume rose 5%, cause pore internal loose, strength fell 0.74%; Cement of a few aperture increase to 7 nm, can lead to internal form lots of pore channels, intensity decreased. when the most several aperture is more than 10 nm, cement strength average less than 41.4 Mpa; Age can effectively passivation cement phase crystallization geometrical shape, and effective crystallization refined grain size.
