研究了氯离子在使用和不使用石灰石填料制成的纯水泥浆和砂浆中的扩散情况。为了研究石灰石填料的效果，所有混合物均按固定的水灰比（0.55）制备。测试结果表明，石灰石填料的添加降低了氯离子的扩散系数。这种减少归因于石灰石填料颗粒对系统弯曲度的影响。结果还表明，界面的存在对氯离子扩散系数的影响有限。
The diffusion of chloride ions in neat cement pastes and mortars made with and without a limestone filler was investigated. In order to study the effect of the limestone filler, all mixtures were prepared at a fixed water cement ratio (0,55). Test results indicate that the addition of a limestone filler reduces the diffusion coefficient of chloride ions. This reduction is attributed to the effect of the limestone filler particles on the tortuosity of the system. Results also indicate that the presence of interfaces has only a limited effect on the diffusion coefficient of chloride ions.
