Lightweight concrete without alkali aggregate reaction as well as preparation method and application of lightweight concrete
The invention discloses lightweight concrete without alkali aggregate reaction as well as a preparation method and application of the lightweight concrete. The lightweight concrete comprises the following components in parts by weight: 40-50 parts of perlite; 750 to 850 parts of zeolite; 210 to 230 parts of cement; 100 to 120 parts of metakaolin; 7-8 parts of a water reducing agent; and 155 to 165 parts of water. The alkali-free aggregate reaction lightweight concrete is prepared by using the perlite fine aggregate with high alkali activity and the zeolite coarse aggregate without alkali activity and doping the metakaolin into the cement. While the concrete is lightened, the high-alkali active aggregate is introduced into an aggregate system.
本发明公开了一种无碱骨料反应的轻质混凝土及其制备方法和应用，其包括如下按重量份计算的组分：珍珠岩40～50份；沸石750～850份；水泥210～230份；偏高岭土100～120份；减水剂7～8份；水155～165份。本发明使用高碱活性的珍珠岩细骨料、无碱活性的沸石粗骨料，同时在水泥中掺入偏高岭土，制成了无碱骨料反应的轻质混凝土。在混凝土轻质化的同时，将高碱活性骨料引入骨料体系。
