摘要
水泥灌浆液作为一个常用的灌浆材料,在工程实际中广泛使用。不同的水灰比和不同减水剂掺量的水泥灌浆液,其最终硬化后具有一定的收缩性,其收缩后的强度直接影响最终灌浆效果。通过对其进行研究,发现水泥灌浆液结石强度具有一定的尺寸效应。不同的水灰比和不同的减水剂掺量对水泥灌浆液终的强度结果影响各不相同。
Cement grouting is widely applied in engineering as common grouting materials. Cement grouting materials mixed with different dosages of water reducing agents and water-to-cement ratio can contract in varying degrees after hardening, which determines the strength of cement. It is crucial to study the strength since grouting is directly affected by it. Results show that the strength has sort of size effects. Besides, proportions of cement-to-water ratio and water reducing agents result in varied strength of final products.
