Electrostatically charged cement particles could be synthesized by the simple method; Charged cement solidification. Voltage potential differences were ranged from 1 to 12 mV, which was lower than the target value (100 mV). Electrolytically-generated gas inhibited continuous contact between the electrode and cement materials, and thus decreased charging efficiency.Electrostatically charged parts were pulverized and their mineralogical compositions were analyzed by XRD. Elemental iron was found in particular in positive-charged parts. Further study is necessary to indentify certain minerals which contributed to electrostatic charge.

可以通过简单的方法合成带静电的水泥颗粒；带电水泥凝固。电压电位差范围为 1 至 12 mV，低于目标值（100 mV）。电解产生的气体抑制了电极和水泥材料之间的连续接触，从而降低了充电效率。将静电充电部件粉碎，并通过 XRD 分析其矿物成分。特别是在带正电的部分中发现了元素铁。有必要进一步研究以确定某些导致静电荷的矿物质。
