Nuclear Magnetic Resonance Analysis of Air Entraining Natural Pumice Concrete Freeze-thaw Damage Xiao Xiao Wang1, a, Xiang Dong Shen2,b , Hai Long Wang3,c and Hong Xia Zhao4,d 1,2,3 College of water conservancy and civil engineering , Inner Mongolia Agricultural University, Hohhot 010018, China 4 Shanghai Niumag Electronic Technology Co.
Because air entrained concrete has better anti permeability, anti-frost and anti-corrosion performances, it has been applied to practical engineering.
NMR technology in the field of geotechnical engineering has made a lot of achievements, at present this technology has become a new method and means of core physical property analysis[4,5].In this paper, we take the concrete using the air-entrained natural pumice of Inner Mongolia as the coarse aggregate sample; then, we conduct freeze-thaw tests with 200 cycles indexes and ultrasonic testing; next we apply an NMR analyzer for relaxation measurement and imaging measurement; finally, we analyze and discuss the distribution of the T2 spectrum, and internal pore distribution characteristics of air-entrained natural pumice lightweight aggregate concrete.
