Fabricated structure joint low-temperature grouting material and quality control method thereof
The invention discloses a low-temperature grouting material for an assembly type structure joint and a quality control method of the low-temperature grouting material. The low-temperature grouting material comprises water, a cementing material and sand, the concrete further comprises gravel, fibers, silica fume, an early strength agent, an expanding agent, an anti-cracking agent, an anti-freezing agent and a water reducing agent. The weight part of the cementing material is 40-60 parts; 20 to 40 parts by weight of sand; the weight part of the broken stone is 5-12; 2-6 parts by weight of silica fume; the weight part of the fiber is 0.1-2 parts; 0.5-3 parts by weight of an early strength agent; the weight part of the expanding agent is 0.1-1 part; the weight part of the anti-cracking agent is 0.1-1 part; the weight part of the anti-freezing agent is 0.1-1 part; the weight part of the water reducing agent is 0.1-1 part; the ratio of water to materials is 0.09 to 0.11. The technical problems that a traditional grouting material is large in dry shrinkage, insufficient in strength, poor in low-temperature resistance and small in elastic modulus under the low-temperature condition are solved.
一种装配式结构连接缝低温灌浆料及其质量控制方法，包括有水、胶凝材料和砂子；还包括有碎石、纤维、硅灰、早强剂、膨胀剂、抗裂剂、抗冻剂和减水剂；所述胶凝材料的重量份为40～60份；砂子的重量份为20～40份；碎石的重量份为5～12份；硅灰的重量份为2～6份；纤维的重量份为0.1～2份；早强剂的重量份为0.5～3份；膨胀剂的重量份为0.1～1份；抗裂剂的重量份为0.1～1份；抗冻剂的重量份为0.1～1份；减水剂的重量份为0.1～1份；水料比为0.09～0.11。本发明解决了传统的灌浆料在低温条件下干收缩较大、强度不足、抗低温性能差和弹性模量小的技术问题。
