Preparation method of harsh concrete curb reinforcing agent with ultralow water cement ratio
The invention discloses a preparation method of a dry and hard concrete curb reinforcing agent with an ultralow water cement ratio, and the preparation method of the reinforcing agent comprises the following steps: cutting and grinding poultry feathers and wool to form powder A, uniformly mixing a sodium hydroxide solution with ethanol and alkaline hydrogen peroxide to form a solution B, forming a mixed solution C by the powder A and the solution B, and uniformly mixing the mixed solution C with the water cement ratio to form a mixture B; adding stearic acid and ethanol to form a solution D, adding the mixed solution C and the solution D into the nano calcium silicate emulsion, dispersing uniformly and solidifying to form a solid E; the solid E is cut, smashed and ground into microparticles, and the reinforcing agent is obtained. The reinforcing agent disclosed by the invention is added into dry hard concrete, and poultry feathers and wool are mixed for use, so that the volume stability of the curb is favorably maintained, and defects are reduced; meanwhile, due to the action of the sodium stearate and the wool fibers, the internal structure and the adhesion of the dry hard concrete are improved, and the mechanical property of the concrete is improved.
本发明公开了一种超低水灰比干硬性混凝土路缘石增强剂的制备方法，本发明所述增强剂的制备方法，包括：将禽类羽毛和羊毛切割并磨细形成粉末A，将氢氧化钠溶液与乙醇、碱性过氧化氢混合均匀形成溶液B，粉末A与溶液B形成混合液C，硬脂酸与乙醇中形成溶液D，混合液C和溶液D加到纳米硅酸钙乳浊液中分散均匀凝固形成固体E；将固体E切割粉碎并研磨成微颗粒得所述增强剂。本发明所述增强剂加入到干硬性混凝土中，禽类羽毛和羊毛混合使用有利于维持路缘石体积稳定性，降低缺陷；同时，由于硬脂酸钠和羊毛纤维的作用，使得干硬性混凝土内部结构和粘接性得以改善，提高了混凝土的力学性能。
