Concrete admixture as well as preparation method and application thereof
The invention discloses a concrete admixture as well as a preparation method and application thereof. The concrete admixture comprises the following components in percentage by mass: 30-35% of a sugar beet pulp extract, 55-60% of a kidney bean root nodule extract and 10% of an adhesive. An acquisition method of the sugar beet pulp extract comprises the following steps: pretreating sugar beet pulp by using sodium sulfite, removing lignin in the sugar beet pulp, crushing and sieving, adding an acid solution for soaking and acidolysis, and finally drying and pulverizing to obtain the sugar beet pulp extract. The obtaining method of the kidney bean root nodule extract comprises the following steps: taking a kidney bean root nodule part, washing, drying, crushing and sieving to obtain kidney bean root nodule powder, adding an alkaline solution for soaking, centrifuging to obtain supernate, and finally drying and pulverizing to obtain the kidney bean root nodule extract. During preparation, the sugar beet pulp extract is used as a wall material, the kidney bean root nodule extract is used as a core material, the core material is wrapped by the wall material through an adhesive, and the concrete admixture is obtained. The invention has the functions of retarding and corrosion inhibition, the raw materials are natural and pollution-free, and the preparation method is simple.
本发明公开了一种混凝土外加剂、其制备方法及应用，混凝土外加剂以质量计包括30%~35%的甜菜渣提取物、55%~60%的芸豆根瘤提取物和10%的粘合剂；其中甜菜渣提取物的获取方法为：使用亚硫酸钠对甜菜渣进行预处理，去除甜菜渣中的木质素，经粉碎过筛后，加入酸溶液进行浸泡酸解，最后烘干制粉得到甜菜渣提取物；芸豆根瘤提取物的获取方法为：取芸豆根瘤部分，经洗净烘干、粉碎过筛后，制得芸豆根瘤粉末，再加入碱溶液进行浸泡，离心取上清液，最后烘干制粉得到芸豆根瘤提取物；制备时，将甜菜渣提取物作为壁材，将芸豆根瘤提取物作为芯材，将壁材通过粘合剂包裹芯材，即得到混凝土外加剂。本发明兼具缓凝和阻锈功能，原料天然无污染，制备方法简单。
