Concrete with high chloride ion erosion resistance and preparation method thereof
The invention discloses concrete with high chloride ion erosion resistance and a preparation method thereof. The concrete comprises the following components in parts by weight: 600-800 parts of cement; 100 to 350 parts of fly ash; 50 to 100 parts of silica fume; 50 to 100 parts of metakaolin; 800 to 1000 parts of river sand; 180 to 200 parts of deionized water; and 30-40 parts of a water reducing agent. The preparation method comprises the following steps: firstly, mixing and adding the cement, the fly ash, the silica fume and the metakaolin into a stirring pot, mixing and stirring for 90 seconds at the rotating speed of 80-100r/min, then adding the mixed river sand into the stirring pot, mixing and stirring for 60 seconds at the rotating speed of 80-100r/min, then adding the deionized water and the polycarboxylic acid water reducing agent into the stirring pot, stirring for 180 seconds at the rotating speed of 300-360r/min after the raw materials in the stirring pot form slurry, and mixing and stirring for 60 seconds at the rotating speed of 80-100 r/min. The concrete is used for structures of high-chloride-ion environments such as ocean, the durability of the structures can be effectively improved, and the service life of components is prolonged.
本发明公开了一种高抗氯离子侵蚀混凝土及其制备方法。该混凝土包括如下重量份的组分：水泥600～800份；粉煤灰100～350份；硅灰50～100份；偏高岭土50～100份；河砂800～1000份；去离子水180～200份；减水剂30～40份。制备方法是先将水泥、粉煤灰、硅灰以及偏高岭土混合加入到搅拌锅中，以80～100r/min的转速混合搅拌90s，再将混合好的河砂加入其中，以80～100r/min的转速混合搅拌60s，然后将去离子水和聚羧酸减水剂加入到搅拌锅中，当搅拌锅中的原材料成浆体后，先以300～360r/min的转速搅拌180s，再以以80～100r/min的转速混合搅拌60s即可。本发明用于海洋等高氯离子环境的结构，可有效提高结构的耐久性能，提高构件的服役寿命。
