The invention belongs to the field of mortar, particularly relates to screw spike anchoring mortar, and provides the following scheme aiming at the problems that the existing screw spike anchoring mortar is poor in anti-cracking effect, weak in water seepage prevention capability, easy to crack after being coagulated and short in service life: the screw spike anchoring mortar is prepared from the following raw materials in parts by weight: 20-40 parts of Portland cement; 10 to 15 parts of fine aggregate; 5 to 15 parts of sulfur powder; 5 to 10 parts of paraffin wax; 5 to 10 parts of polysulfide rubber; 3 to 7 parts of gypsum; 5 to 8 parts of bauxite; 1-5 parts of drinking water; 1-3 parts of coarse aggregate; and 2-8 parts of an additive. The screw spike anchoring mortar disclosed by the invention has a relatively good anti-cracking effect, strong water seepage prevention capability and relatively strong weather resistance, and the admixture can be diluted by drinking water, so that the admixture can be mixed with the mortar more quickly, and the screw spike anchoring mortar is not easy to crack after being quickly coagulated.
本发明属于砂浆领域，尤其是一种螺旋道钉锚固砂浆，针对现有螺旋道钉锚固砂浆抗开裂效果较差，防渗水能力弱，在凝结后易发生开裂，使用寿命较短的问题，现提出如下方案，由以下重量份数的原料制备而成：硅酸盐水泥：20‑40份；细骨料：10‑15份；硫磺粉：5‑15份；石蜡：5‑10份；聚硫橡胶：5‑10份；石膏：3‑7份；铝矾土：5‑8份；饮用水：1‑5份；粗骨料：1‑3份；外加剂：2‑8份。本发明的螺旋道钉锚固砂浆具有较好的抗开裂效果，防渗水能力强，耐候性较强，饮用水可以稀释外加剂，可使其与砂浆更快混合，在快速凝结后不易发生开裂。
