Nano calcium carbonate modified cement-based grouting full-length anchoring material and preparation method thereof
The invention belongs to the technical field of grouting materials, and particularly relates to a nano calcium carbonate modified cement-based grouting full-length anchoring material and a preparation method thereof. The grouting full-length anchoring material comprises the following components in parts by mass: 800-1100 parts of standard cement, 0-8 parts of a water reducing agent, 20-100 parts of an expanding agent, 5-50 parts of an accelerator and 0-50 parts of nano calcium carbonate. Compared with the existing cement grouting material, the cement grouting material disclosed by the invention has the advantages that the fluidity is improved, the cement grouting material has good bleeding property, the volume is slightly expanded, the flexural strength and compressive strength of cement are improved, the flexural-compressive ratio also presents a rising trend, and the cement grouting material shows higher drawing strength in a full-length grouting system as an anchoring agent.
本发明属于注浆材料技术领域，尤其是一种纳米碳酸钙改性水泥基注浆全长锚固材料及制备方法。本发明的注浆全长锚固材料包括800‑1100质量份的基准水泥、0‑8质量份的减水剂、20‑100质量份的膨胀剂、5‑50质量份的速凝剂及0‑50份质量份的纳米碳酸钙。本发明与现有水泥注浆材料相比，提高了流动度，拥有良好的泌水性，体积发生微膨胀，水泥的抗折和抗压强度得到提升，折压比也呈现上升趋势，作为锚固剂在全长注浆体系中表现出更高拉拔强度。
