Preparation method of concrete containing modified cassava starch-polycarboxylic acid composite water reducing agent
The invention discloses a preparation method of concrete containing a modified cassava starch-polycarboxylic acid composite water reducing agent, and belongs to the field of building materials. The preparation method of the concrete comprises the following steps: adding the general portland cement, the fly ash, 75 parts of the water, the sodium carboxymethyl cellulose, the sand and the stones intoa stirrer and stirring for 15 minutes; adding the modified cassava starch-polycarboxylate superplasticizer, stirring for 5 minutes, and standing for 15 minutes; and adding ferrous sulfate into a ferrous sulfate stirrer, stirring for 4 minutes, and putting into a corresponding template to obtain the product. The concrete preparation method provided by the technical scheme has the advantages of easiness in operation, easiness in large-scale production and the like; the obtained concrete is smooth in appearance and good in durability, sand holes and air holes are not formed in the surface of theconcrete, and good mechanical properties such as high compressive strength are achieved.
本发明公开了一种含改性木薯淀粉‑聚羧酸复合减水剂混泥土的制备方法，属于建筑材料领域。所述混泥土的制备方法，包括以下步骤：将通用硅酸盐水泥、粉煤灰、水75份、羧甲基纤维素钠、砂和石子加入搅拌机中搅拌15min；加入改性木薯淀粉‑聚羧酸减水剂搅拌5min，放置15min；加入硫酸亚铁搅拌机搅拌4min，放入相应的模板中即可。本技术方案提供的混泥土制备方法，具有操作容易，易于大规模生产等优势；所得的混泥土外观平整，耐久性好，表面没有砂眼和气孔，具有较高的抗压强度等良好的力学性能。
