Seawater-resistant reinforced concrete admixture and preparation method thereof
The invention discloses a seawater-resistant reinforced concrete admixture and a preparation method thereof. The seawater-resistant reinforced concrete admixture is characterized by comprising the following raw materials by mass: 70-80 parts of beta-sodium naphthalene sulfonate formaldehyde polycondensate, 5-10 parts of chitosan, 4-7 parts of calcium silicate, 2-8 parts of a silane coupling agent,1-2 parts of polyvinylpyrrolidone, 1-2 parts of chromium lactate, 3-5 parts of carbonized microfibrillated fiber, 1-3 parts of a rosin thermal polymer and 1-3 parts of zirconium oxide fiber; whereinthe carbonized microfibrillated fiber is a product of high-temperature anaerobic carbonization of microfibrillated plant fiber. The seawater-resistant reinforced concrete admixture provided by the invention further improves the flexural strength and compressive strength of concrete in a high-salinity environment.
本发明公开了一种抗海水增强混凝土外加剂及其制备方法，其特征是包括以下原料β基萘磺酸钠甲醛缩聚物70‑80质量份、壳聚糖5‑10质量份、硅酸钙4‑7质量份、硅烷偶联剂2‑8质量份、聚乙烯吡咯烷酮1‑2质量份、乳酸铬1‑2质量份、碳化微纤化纤维3‑5质量份、松香热聚物1‑3质量份、氧化锆纤维1‑3质量份；所述碳化微纤化纤维为微纤化植物纤维进行高温无氧碳化的产物。本发明的抗海水增强混凝土外加剂进一步提高混凝土在高盐渍环境下的抗折强度和抗压强度。
