Paenibacillus Mucilaginosus, Microorganism-Activated Circulating Fluidized Bed (CFB) Fly Ash-Based Cementitious Material, Preparation Method and Use

Abstract

The present disclosure provides a Paenibacillus mucilaginosus LT1906 and use thereof, and a microorganism-activated circulating fluidized bed (CFB) fly ash-based cementitious material and a preparation method and use thereof, belonging to the technical field of cementitious materials. The Paenibacillus mucilaginosus LT1906 has a deposit number of CGMCC No. 21337. The strain is capable of dissolving silicate minerals and aluminosilicate minerals in the CFB fly ash to increase dissolution of active SiO2. The strain is used for activating the CFB fly ash-based cementitious material, to ameliorate a large water demand and a low early strength of the cementitious material, thereby improving comprehensive utilization of the CFB fly ash in the field of building materials.
