Preparation method of modified seed fiber toughened concrete
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of modified seed fiber toughened concrete. The preparation method specifically comprises the steps that firstly, an ethanol solution is used for pretreating composite seed fibers, floating dust in the composite seed fibers is removed, then the composite seed fibers with the floating dust removed are placed in deionized water, urea and a ternary carboxyl weak acid pretreatment solution are sequentially added, stirring and mixing are conducted, and a first mixture is obtained; crushing the mixture I to fully esterify the composite seed fibers in the mixture I, drying and crushing the esterified seed fibers to obtain seed fiber powder, and uniformly mixing the seed fiber powder with ordinary Portland cement and fine aggregate river sand to obtain a mixture II; and finally, adding a polycarboxylic acid water reducer solution into the mixture II, and uniformly stirring to obtain the modified seed fiber toughened concrete.
本发明属于建筑材料技术领域，具体涉及一种改性种子纤维增韧混凝土的制备方法；所述制备方法具体为：先使用乙醇溶液对复合种子纤维进行预处理，去除复合种子纤维内的浮尘，然后将去除浮尘的复合种子纤维置于去离子水中，并依次加入尿素和三元羧基弱酸预处理液进行搅拌混合制得混合物一，对混合物一进行破碎处理，使混合物一中的复合种子纤维充分酯化，并对酯化后的种子纤维进行干燥、粉碎处理得到种子纤维粉末，再将种子纤维粉末与普通硅酸盐水泥、细骨料河砂一起混合均匀得到混合物二，最后向混合物二中加入聚羧酸减水剂溶液并搅拌均匀即可制得改性种子纤维增韧混凝土。
