Microbial remediation agent with strength simultaneously increased with strength of concrete matrix and preparation method thereof
The invention discloses a microbial remediation agent with strength simultaneously increased with strength of concrete matrix and a preparation method thereof. The microbial remediation agent is of a core-shell structure comprising a core material and a wall material, the core material is microbial powder, and the wall material is a low-alkalinity inorganic cementing material doped with a strength synergistic increasing component, wherein the strength synergistic increasing component is one or more of fly ash, metakaolin, granulated blast furnace slag and granulated phosphorus slag. The preparation method comprises the following steps: uniformly mixing the strength synergistic increasing component with the low-alkalinity inorganic cementing material to obtain wall material powder; the preparation method comprises the following steps: firstly preparing a microbial powder inner core by adopting a granulator, and then coating the wall material; taking out and maintaining to obtain the microbial remediation agent. According to the microbial remediation agent, the low-alkalinity inorganic cementing material doped with the strength synergistic increasing component serves as the wall material, microorganisms can be kept complete and respond in time in the stirring process with concrete, meanwhile, after the microbial remediation agent is doped with the concrete, the strength of the microbial remediation agent and the strength of the concrete matrix can be increased at the same time, and the strength of the concrete cannot be degraded.
本发明公开了一种与混凝土基体强度同增长的微生物修复剂及其制备方法。该微生物修复剂为包括芯材和壁材的核壳结构，芯材为微生物粉体，壁材为掺有强度协同增长组分的低碱性无机胶凝材料；其中，强度协同增长组分为粉煤灰、偏高岭土、粒化高炉矿渣、粒化磷渣中的一种或几种。其制备方法为：将强度协同增长组分与低碱性无机胶凝材料混合均匀，得壁材粉料；采用造粒机先制备微生物粉体内核，然后包覆壁材；取出养护，即得微生物修复剂。本发明的微生物修复剂以掺有强度协同增长组分的低碱性无机胶凝材料为壁材，能够使微生物在与混凝土的搅拌过程中保持完整并及时响应，同时，其掺入混凝土后可与混凝土基体强度同增长，不会劣化混凝土强度。
