Abstract

The invention discloses a method for rapidly manufacturing assembled building components by using microorganisms. The method uses polysaccharides deposited or produced by microorganisms to wrap aggregates, and is obtained by adding nutrient solution, cementing materials, fillers, fibers and admixtures. Slurry with suitable fluidity is molded, and then after rapid carbonization and drying, prefabricated components with designed strength can be obtained in a few hours. This method can reduce the leaching of harmful substances in aggregates and fillers in prefabricated components through microbial encapsulation, and at the same time avoid the use of cement. It has the characteristics of local materials and rapid prototyping. Prefabricated component factory site investment, improve the construction speed of prefabricated buildings.

Description

technical field [0001] The invention relates to the field of prefabricated buildings and new building materials, in particular to a method for rapidly manufacturing prefabricated building components by using microorganisms. Background technique [0002] Ecological and environmental problems such as resource waste, noise pollution, and construction waste brought about by the on-site construction of traditional cast-in-place concrete structures can no longer meet the requirements of my country's new urbanization development. At the same time, with the disappearance of my country's demographic dividend, the construction industry will also face the problems of labor shortage and rapid rise in labor costs. Building industrialization can realize the industrialization of the whole life cycle of buildings from design to production and construction, save resources and energy in the process of building construction and use to the greatest extent, improve the quality and efficiency of ...
