The effect of enzyme induced calcite precipitation （EICP） technology on the properties of tabia was studied by means of scanning electron microscope and X-ray diffractometry. The results show that urease activity increases approximately linearly with increasing of soybean powder mass concentration， and its optimum pH value is 3-11. When the pH value is 12， the activity drops sharply. Compared with the control sample of tabia， the carbonization speed of tabia modified with urease increases by 94%-112% in 14 days， the compressive strength increases by 68%-103% in 28 days， the weather resistance increases by 150%-200%， the surface hardness increases by 15.0%-18.3% in 60 days. The calcium carbonate crystals produced by the control sample of tabia are loose. After adding urease， long-strip crystals and cluster-like crystals appear in the tabia， and with the increase of soybean powder mass concentration， the cluster-like crystals increase relatively， and the long-strip crystals decrease relatively， the performance of tabia also gradually improves.
