研究了在商品硅酸盐水泥中掺加细、粗级配胶凝材料(SCM)制备高性能GAP级配水泥的可行性，并对比评价了SCM在GAP级配水泥和夹层水泥中的应用效果。结果表明，GAP级配水泥的颗粒尺寸分布更接近于Fuller分布，这是由于有意添加了细粒和粗粒的SCM，导致了较高的初始堆积密度。矿渣颗粒主要分布在GAP级配水泥的细粒中，其水化效率显著提高，占水化产物总量的43.5%。结果表明，由于“粒度细化”和“孔径细化”，GAP级配水泥浆体具有均匀致密的微观结构，其凝结时间显著缩短，早期强度和后期强度均显著提高。
This paper examined the feasibility of preparing high performance gap-graded blended cements by adding fine and coarse supplementary cementitious material (SCM) fractions into commercial Portland cement, and the efficiency of SCMs in gap-graded blended cements and interground blended cements were comparatively evaluated. The results show that the particle size distribution of gap-graded blended cements was much closer to a Fuller distribution, due to the intentional addition of fine and coarse SCMs, resulting in a higher initial packing density. As granulated blast furnace slag (GBFS) was mainly arranged in the fine fraction of the gap-graded blended cements, its efficiency was increased dramatically, contributing to 43.5% of the total measured hydration products. As a result, gap-graded blended cement pastes presented a homogeneous and dense microstructure due to “grain size refinement” and “pore size refinement”, therefore their setting times were decreased significantly, and both early and late strengths were increased remarkably in comparison to the interground blended cements investigated in this study.
