    摘要:

    【目的】利用固废设计胶凝材料替代水泥,能够减少能源和资源消耗与环境污染,并实现固废资源化利用。基于碱激发胶凝材料的反应机理及其原材料组分的作用机制,提出一种全固废碱激发胶凝材料设计方法。【方法】设计了组分为电石渣(CCR)、高炉矿渣(GGBS)、粉煤灰(FA)、磷石膏(PG)的CGF+P系列胶凝材料,并利用净浆宏微观试验验证该设计方法。【结果】碱激发剂和高反应活性火山灰质材料对凝结时间影响显著,其含量越高,初凝时间和终凝时间越短;强度受碱激发剂与火山灰质材料的相对含量支配,高反应活性火山灰质材料含量越高早期强度越高,反之亦然。【结论】本文提出的全固废碱激发胶凝材料设计方法包括组分分类方法、组分筛选方法和组分配比设计方法,具有一定的实用价值。

    Abstract:

    [Purposes] The design of cementitious materials utilizing solid waste to replace cement, which reduces energy and resource consumption and environmental pollution, as well as realizes the resource utilization of solid waste. Based on the reaction mechanism of alkali-activated binder and the action mechanism of their raw material components, this paper proposes a design method of all-solid-waste-based alkali-activated binders. [Methods]The CGF+P series cementitious materials comprising calcium carbide slag (CCR), ground granulated blast furnace slag (GGBS), fly ash (FA), and phosphogypsum (PG) are designed, and the design method is verified by using macro and micro tests of paste. [Findings] The alkali activator and pozzolanic materials with highly activity have a significant effect on the setting time of paste, the higher its content, the shorter the initial and final setting time; The strength of paste is governed by the relative content of alkali activator and pozzolanic materials, the higher the content of pozzolanic materials with highly activity the higher the early strength, and vice versa. [Conclusions] The design method of all-solid-waste-based alkali-activated binders includes component classification method, component screening method, and component distribution ratio design method, which has a practical value.
