Title
(EN) Method for preparing building material by complex microorganism mineralization
(ZH) 一种利用复合微生物矿化制备建材的方法
Abstract
(EN) The invention discloses a method for preparing a building material by complex microorganism mineralization. The method comprises the steps of cultivating microorganism l strains with the acid production function and microbial strains with the mineralization sediment function, and obtaining a microorganism additive; mixing the microorganism additive, mineral powder and water to be evenly stirred toobtain complex microorganism slurry; and carrying out curing forming on the complex microorganism slurry to obtain a complex microorganism building material product. Calcium magnesium mineral use rates in materials like industrial solid waste, waste concrete, cement and the like can be sufficiently used, more stable carbonate mineralization is formed, the material phase mineralization strength isimproved, and the strength and the volume stability of the building material product with complex microorganisms can be improved.
(ZH) 本发明公开了一种利用复合微生物矿化制备建材的方法,包括将具有产酸功能的微生物菌种和矿化沉积功能的微生物菌种进行培养,得到微生物添加剂;将微生物添加剂、矿物粉体和水进行混合,搅拌均匀,得到复合微生物浆料;将复合微生物浆料进行固化成型,得到复合微生物建筑材料制品。本发明充分利用工业固废、废弃混凝土及水泥等物料中的钙镁矿物利用率,形成更多稳定性碳酸盐矿化,并提升物相矿化强度,提高了携复合微生物的建筑材料制品强度和体积稳定性。
