Subject to the actual geography and climate of the loop irrigation environment as the foundation, study of natural rubber pumice concrete frost resistance of the improvement mechanism, and the view of the cold regions special geographical climate adaptability. Use of Inner Mongolia region of enrichment pumice resources, through the scrap tire rubber powder modified pumice concrete antifreeze, anti-permeability, impact resistant wear-resisting performance etc. Through the analysis of indoor and outdoor and microscopic quantitative expression of the interface, and concludes that the natural pumice light weight aggregate concrete micro powder interface properties, the pore characteristic and the macroscopic mechanical properties (bending, compressive, tensile, anti-permeability, antifreeze and resistance to abrasion resistance) the inner relationship between the, this paper summarizes the mesoscopic change and powder concrete macroscopic mechanical properties of the coupling law; Through the observation of the natural experiment data gate and set up a corresponding temperature gradient ice-brake body shock model; Through the three temperature of freeze-thaw cycle simulation test to freeze, the freezing and ice water impact before and after the cement hydration products structure form, transition zone interface, it is concluded that the cement base material internal composition change, powder-water slurry-aggregate interface transition zone geometry physical properties characterization and pore structure change rule.
