Additive for cement grouting material and application thereof
The invention discloses an additive for cement grouting material and application thereof. The additive comprises a powder material; the powder material is prepared from the following raw material components: quick-hardening sulphoaluminate cement, clay, a high-efficiency water reducing agent, a retarder, an anti-dispersing agent, nano-scale silica fume and an early strength agent; the application of the additive in the stratum cement grouting material comprises the following steps: uniformly mixing the additive with the Portland cement to obtain a first mixture; uniformly mixing the first mixture with water to obtain the cement grouting material; wherein; the mass ratio of the first mixture to the water is (0.5-0.8): 1. Therefore, according to the embodiment of the invention, the additive formed by various components is added into the Portland cement, so that the compressive strength of the cement formed by the stratum cement grouting material is improved, and the solidification of the cement grouting material in the stratum is facilitated; the technical problem that in the prior art, due to the fact that traditional cement is prone to loss in a loose pore stratum, the grouting range is difficult to control is solved.
本发明公开了一种用于水泥注浆料的添加剂及其应用；所述添加剂包括粉料；所述粉料包括如下原料组分：快硬硫铝酸盐水泥、粘土、高效减水剂、缓凝剂、抗分散剂、纳米级硅灰，以及早强剂；所述添加剂在地层水泥注浆料中的应用，包括：将所述添加剂与所述硅酸盐水泥混合均匀，得到第一混合物；将所述第一混合物和水混合均匀，得到水泥注浆料；其中；第一混合物和所述水的质量比为0.5‑0.8:1。由此，本实施例将各种组分所形成的添加剂添加至硅酸盐水泥中，不仅提高了地层水泥注浆料所形成水泥的抗压强度，而且有利于地层中水泥注浆料的凝固；解决了现有技术中由于传统水泥在松散孔隙地层中易流失导致注浆范围难以控制的技术问题。
