摘要
通过试验证实了微珠在很高的压力下仍然完好,其密度增加是由于水被压入部分具有较大孔径的微珠中所致。表明了微珠利用的可靠性。同时还对微珠低密度水泥浆的试验方法提出了异议。
In this paper, it is proven by testing result that the fine-grains could be in good condition even under great pressure. The increasing of density is due to the water what is pressed into, some fine-grains with bigger holes. The paper reveals the reliability of fine-grain applying, and also raises an objection about the testing method used for fine-grain cement grout with low density.
