AB  - The microbially-induced calcium carbonate precipitation (MICP) technique has 
      shown great robustness in dealing with soil and groundwater contamination 
      problems. A typical result of the implementation of MICP technique is a change in 
      the pore structure. In this study, the effects of MICP on the pore structure of 
      yellow sandstone from the Zigong area, Sichuan, China under different conditions, 
      (e.g., temperature, pH, and calcium ion concentration) are investigated using 
      LF-NMR resonance. The pore network of yellow sandstone is accurately measured 
      using the peak area of the T(2) spectral signal. The distribution of calcium 
      carbonate in the pores of the yellow sandstone is characterized by the magnitude 
      of the T(2) signal variation. The results show that the precipitation of calcium 
      carbonate caused by MICP tends to be deposited in relatively large pores. 
      However, the calcium carbonate precipitates in the smaller pores at a higher 
      temperature. A higher pH considerably enhances the precipitation, and the 
      alkaline environment tends to cause the precipitation of the calcium carbonate in 
      the large pores. Although the amount of produced calcium carbonate continuously 
      increases as the MCIP process continues, which is expected, the production 
      efficiency decreases steadily.
