Environment-friendly C80 high-strength high-performance machine-made sand concrete and preparation method thereof
The invention provides environment-friendly C80 high-strength high-performance machine-made sand concrete and a preparation method thereof. The environment-friendly C80 high-strength high-performance machine-made sand concrete is prepared from the following components in parts by weight: 320 to 345 parts of cement, 139 to 149.5 parts of water, 40 to 85 parts of fly ash, 107 to 115 parts of mineral powder, 26.8 to 28.8 parts of silica fume, 14 to 43 parts of original-state machine-made sandstone powder, 687 to 707 parts of machine-made sand, 1090 to 1110 parts of gravel and 3 to 4 parts of a water reducing agent. The fixed parts by weight of the cement, the mineral powder, the fly ash, the silica fume, the machine-made sand, the original-state machine-made sandstone powder and the gravel are mixed and stirred, then the water and the water reducing agent are added, and stirring is conducted, so the freshly-mixed high-strength high-performance concrete is obtained. According to the invention, the use amount of an active admixture can be effectively saved, and the hydration degree and the use efficiency of the active admixture in a cementing material are improved; and meanwhile, waste recycling is realized, and the production cost of the high-strength high-performance concrete is reduced.
本发明提供一种绿色环保C80高强高性能机制砂混凝土及其制备方法，按重量份计包括以下组分：水泥320～345份，水139～149.5份，粉煤灰40～85份，矿粉107～115份，硅灰26.8～28.8份，原状机制砂石粉14～43份，机制砂687～707份，碎石1090～1110份，减水剂3～4份。将定量份数的水泥、矿粉、粉煤灰、硅灰、机制砂、原状机制砂石粉和碎石混合并进行搅拌，随后加入水和减水剂搅拌，得到新拌高强高性能混凝土。本发明可以有效节省活性掺合料的用料，提高胶凝材料中活性掺合料的水化程度和使用效率，同时实现废物再利用，降低高强高性能混凝土的生产成本。
