Early-strength micro-expansion underwater non-dispersible grouting material and preparation method thereof
The invention discloses an early-strength micro-expansion underwater non-dispersible grouting material and a preparation method thereof. The early-strength micro-expansion underwater non-dispersible grouting material comprises the following components in parts by weight: 25-50 parts of Portland cement, 20-40 parts of sulphoaluminate cement, 5-30 parts of mineral powder, 5-30 parts of fine aggregate, 3-10 parts of microbeads, 0.3-2.5 parts of an anti-dispersing agent and 0.27-4 parts of a functional aid, and the sum of the parts by weight of all the components is 100. By implementing the preparation method, the prepared early-strength micro-expansion underwater non-dispersible grouting material has good mechanical properties and working properties and excellent underwater dispersion resistance and filling compactness.
本发明公开了一种早强微膨胀水下不分散灌浆料及其制备方法，所述早强微膨胀水下不分散灌浆料包括以下重量份的组分：硅酸盐水泥25～50份，硫铝酸盐水泥20～40份，矿粉5～30份，细集料5～30份，微珠3～10份，抗分散剂0.3～2.5份，功能助剂0.27～4份，各组分的重量份之和为100份。实施本发明，制备得到的早强微膨胀水下不分散灌浆料具备良好的力学性能、工作性能及优异的水下抗分散及填充密实性。
