阅读说明：本技术 一种基于微生物添加剂的混凝土制作方法 (Concrete manufacturing method based on microbial additive ) 是由 余武威 郝昕哲 李臣亮 逯家辉 于 2020-01-04 设计创作，主要内容包括：本发明公开了一种混凝土添加剂的制作方法,该方法包括一下步骤：制备微生物添加剂,配置巴氏芽孢杆菌菌液,将巴氏芽孢杆菌菌液放入离心机中低温离心10min,之后放入冻干机中冻干,将已配置好的培养粉熟化,随后与已冻干的菌粉混合,即得生物活性添加剂,再与改性活性炭以一定比例混合,放入双层压片机中压制成型,得到片剂型强度添加剂。经液压机检测,含有添加剂的混凝土试块强度有不同提升,且在承压下产生裂缝宽度小于未添加混凝土。(The invention discloses a method for preparing a concrete additive, which comprises the following steps: preparing a microbial additive, preparing a pasteurella bacteria liquid, putting the pasteurella bacteria liquid into a centrifuge for low-temperature centrifugation for 10min, then putting the pasteurella bacteria liquid into a freeze dryer for freeze drying, curing the prepared culture powder, then mixing the culture powder with the freeze-dried bacteria powder to obtain a bioactive additive, mixing the bioactive additive with modified activated carbon according to a certain proportion, putting the mixture into a double-layer tablet press for compression molding, and obtaining the tablet strength additive. The hydraulic press detection shows that the strength of the concrete test block containing the additive is improved differently, and the width of the crack generated under the pressure bearing condition is smaller than that of the concrete without the additive.)

1. The additive is used for preparing the blended concrete.

2. The method of making the concrete of claim 1:

the preparation method of the concrete additive comprises the following components in percentage by mass: 50-80 parts of modified white carbon black, 4-20 parts of ethyl cellulose, 1-5 parts of microcrystalline cellulose, 7-15 parts of magnesium stearate, 5-10 parts of activated carbon, 25-40 parts of calcium chloride and 5-10 parts of modified bacterial powder. The tablet is formed by composite pressing of a double-layer tablet press, wherein the layer A uses white carbon black as a main raw material, and the layer B uses CaCl₂Is used as the main raw material.

3. The microbial additive of claim 2, wherein the layer a tablet is prepared by a method comprising: the method comprises the following steps: taking 2-10 parts of ethyl cellulose, 1-5 parts of microcrystalline cellulose, 5-10 parts of magnesium stearate, 5-10 parts of activated carbon, 5-10 parts of calcium chloride and 50-80 parts of modified white carbon black by mass, putting the raw materials into a high-speed pulverizer for pulverization, and pouring the pulverized raw materials into a granulator to obtain fine particles with the same particle size.

4. The modified white carbon black according to claim 3, wherein the preparation method of the modified white carbon black comprises the following steps: preparing a bacterial solution, soaking the white carbon black in the bacterial solution, supplementing urea and glycerol during the soaking, filtering after 48 hours to obtain the white carbon black, drying at 50-60 ℃, and crushing and sieving the dried powder to obtain the modified white carbon black.

5. The B layer of claim 2, wherein the B layer tablet is prepared by a method comprising: the method comprises the following steps: 5-10 parts of modified fungus powder, 20-30 parts of calcium chloride, 2-5 parts of magnesium stearate and 2-10 parts of ethyl cellulose are poured into a pulverizer, and then the mixture is poured into a granulator for granulation.
