水泥浆堵漏剂的水泥基材性能对比

Cement Slurry Plugging Agent of Cement Base Material Performance Comparison

针对水泥浆堵漏剂在材料选择上的盲目性,本研究将无机胶凝材料A、B、C在抗压强度、线性膨胀率、杨氏模量、体积模量上进行了对比。结果表明,无机胶凝材料A在30℃、60℃条件下,小时强度发展快,抗压强度高,膨胀率及24 h杨氏模量、体积模量均大于其他两种水泥基材料,适合作为水泥浆堵漏剂的基础材料。

Materials,In this study,A,B and C were compared in compressive strength,linear expansion rate,young's modulus and volume modulus.Results showed that inorganic gelled material under the condition of 30 ℃ 、60 ℃,a hour strength development is fast,high compressive strength.The expansion rate of A and 24 hours of young 's modulus and volume modulus are greater than the other two cement base materials,which are suitable for the basic materials for water cement plugging agent.
