Concrete air-entraining antibacterial agent as well as preparation method and application thereof
The invention discloses a concrete air-entraining antibacterial agent as well as a preparation method and application thereof, relates to a concrete admixture as well as a preparation method and application thereof, and aims to solve the technical problem that a quaternary ammonium salt surfactant in existing concrete cannot play an antibacterial function due to low dosage. The concrete air-entraining antibacterial agent is formed by fixing a quaternary ammonium surfactant in activated carbon. The preparation method comprises the following steps: adding powdery activated carbon into a quaternary ammonium salt surfactant aqueous solution for dipping, and then washing, drying and crushing to obtain the concrete air-entraining antibacterial agent. The air-entraining antibacterial concrete is obtained by adding the air-entraining antibacterial agent into concrete, wherein the mass of the air-entraining antibacterial agent accounts for 0.5-5% of that of Compared with a blank group, the compressive strength breakage of the air-entraining antibacterial concrete is lower than 20%, the porosity is maximally improved by 20%, and the corrosion depth is maximally reduced by 16%. The method can be used in building field.
一种混凝土引气抗菌剂及其制备方法和应用，它涉及混凝土外加剂及其制备方法和应用，它是要解决现有的混凝土中季铵盐表面活性剂因用量低而无法发挥抗菌功能的技术问题，本发明的混凝土引气抗菌剂是将季铵表面活性剂固定在活性炭中形成的。制法：将粉末状活性炭加入到季铵盐表面活性剂水溶液中浸渍，然后洗净、干燥、粉碎，得到混凝土引气抗菌剂。将其按胶凝材料质量的0.5%~5%加入到混凝土中，得到引气抗菌混凝土。相比空白组，引气抗菌混凝土的抗压强度折损低于20%，孔隙率最大提升20%，腐蚀深度最高降低16%。可用于建筑领域。
