▎ 摘　　要

NOVELTY - Prefabricated pile includes quartz sand, 15-25 wt.% magnesium oxide, 5-15% fly ash, 5% slag, 8-12% urea, and 1-4% polyether gel powder. The bacterial suspension includes culture medium, bacterial, graphene oxide, and urea. USE - Prefabricated pile for use in a building material i.e. cement, in infrastructure construction. ADVANTAGE - The prefabricated pile effectively keeps the same height compression strength, and improves the self-repairing effect of the pile. The pile has high-activity magnesium oxide curing body, thus reducing the carbon dioxide emission of the cement prepared by the pile, and realizing the capturing and storing of the carbon-dioxide, and has the effect of energy-saving and environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the prefabricated pile.
