High-strength concrete material for prefabricated duct piece of wind power mixing tower and preparation method of high-strength concrete material
The invention discloses a wind power mixing tower prefabricated duct piece high-strength concrete material and a preparation method thereof.The high-strength concrete material is C80-C95 high-strength concrete and comprises the following components: 560-620 parts of a cementing material, 33-50 parts of silica fume, 80-125 parts of microbeads and 12-20 parts of a water reducing agent; wherein the aggregate sand ratio of the high-strength concrete material is 35%-39%, the real water-binder ratio is 0.20-0.23, the designed volume weight is 2450-2500 parts, and the slump is 180 +/-20 mm; the high-strength concrete material for the prefabricated duct piece of the wind power mixed tower has good durability and flowability, can meet production and construction of a horizontal mold, is easy for manual finishing and plastering, and realizes mold removal in advance while ensuring that the mechanical property and durability of the duct piece concrete meet design requirements; the turnover rate and the production efficiency of the formwork are effectively improved, short-period delivery, transportation and hoisting construction of the mixed tower duct pieces can be achieved, and the production and construction period is shortened.
本发明公开了一种风电混塔预制管片高强混凝土材料及其制备方法，该高强混凝土材料为C80～C95高强混凝土，其组分包括：胶凝材料560～620份，硅灰33～50份，微珠80～125份，减水剂12～20份；其中，该高强混凝土材料的骨料砂率为35％～39％，真实水胶比为0.20～0.23，设计容重为2450～2500份，坍落度为180±20mm；本发明提出的风电混塔预制管片高强混凝土材料具有良好的耐久和流动性，能够满足卧式模具生产施工且易于人工收光抹面，在保证管片混凝土力学性能和耐久性满足设计要求的同时实现提前拆模，有效提高了模板的周转率和生产效率，能够实现短周期混塔管片的发货运输和吊装施工，缩短生产和施工周期。
