Preparation method using fruit extract as concrete admixture
The invention discloses a preparation method using a fruit extract as a concrete admixture. The concrete admixture comprises the following raw materials: fresh fruits, an organic solvent-distilled water extraction solution and organic phosphonate. The method specifically comprises the following steps: step 1, washing fresh fruits, removing rotten parts, airing, and cutting into pieces with scissors for later use; 2, the fruits in the step 1 are placed in a drying oven to be dried for 24 h at the temperature of 60-65 DEG C; 3, crushing the dried fruits in the step 2 through a powder machine, and sieving through a 40-mesh sieve; 4, the fruit powder obtained in the step 3 is put into an organic solvent-distilled water (the volume ratio is 5: 1) extraction solution at the temperature of 5-8 DEG C, and the liquid-material ratio is 50: 1 (mL/g); 5, removing the organic solvent from the substance obtained in the step 4 through reduced pressure distillation to obtain a fruit extract; 6, 5-10 parts of the fruit extract obtained in the step 5 and 2-5 parts of organic phosphonate are added into 15-35 parts of water, and the composite liquid concrete admixture is obtained. The concrete admixture prepared from the fruit extract has retarding and antibacterial effects.
本发明公开了一种利用水果提取物作为混凝土外加剂的制备方法，所述混凝土外加剂包括以下原料：新鲜水果、有机溶剂‑蒸馏水提取溶液，有机膦酸盐。具体包括以下步骤：步骤一：将新鲜水果洗净，剔除腐烂部分，晾干，用剪刀剪碎备用；步骤二：将步骤一所述的水果放置在烘箱中，60‑65℃烘干24h；步骤三：将步骤二所述的水果干通过粉末机进行粉碎并通过40目筛；步骤四：将步骤三所得的水果粉末放入温度为5‑8℃的有机溶剂‑蒸馏水(体积比为5:1)提取溶液中，液料比50:1(mL/g)；步骤五：将步骤四物质通过减压蒸馏去除有机溶剂，得到水果提取物；步骤六：将5‑10份步骤五所得水果提取物与2‑5份有机膦酸盐加入至15‑35份水中，得到复合液体混凝土外加剂。本发明利用水果提取物制备的混凝土外加剂具有缓凝和抗菌作用。
