Low-temperature-resistant high-strength bed mortar and preparation method thereof
The prepared bed mortar can meet the normal construction requirement under the cold condition as low as-15 DEG C without additional refrigeration or auxiliary heating, and only conventional curing is needed. The mortar has the characteristics of good stability and no shrinkage distortion. The 28-day strength is up to 100 MPa, and the stress can be effectively conducted. The excellent hydratability and plasticity can ensure a sufficient construction time window. When filled at the joint of the upper section and the lower section, due to the micro-expansion characteristic of the filler, the filler can completely cover the connecting surface and provide the maximum bearing area, so that the tight connection between the upper tower drum structure and the lower tower drum structure is ensured. Meanwhile, the mortar is free of water seepage, convenient to use, good in durability and low in chlorine content, a steel structure cannot be corroded after long-term use, and generally, the novel low-temperature-resistant high-strength mortar can effectively improve the construction efficiency of a wind power project and guarantee the long-term operation safety of a wind turbine generator set through various excellent properties while meeting severe low-temperature construction conditions.
本发明制备得到的座浆砂浆能够在低至‑15°C的寒冷条件下，无需额外制冷或辅助加热就能达到正常施工要求，仅靠常规养护即可。该砂浆本身具有稳定性好、无收缩变形的特点。28天强度高达100MPa，能有效传导应力。它优异的水化性和可塑性可以保证充足的施工时间窗口。填充在上下节接缝处时，由于自身具有微膨胀特性，能完全覆盖连接面并提供最大的承载面积，确保上下塔筒结构之间的紧密连接。同时，不会渗水、使用方便，耐久性好，含氯量低，长期使用后不会对钢结构产生腐蚀，总体来说，这种新型耐低温高强砂浆通过满足严苛低温施工条件的同时，通过其多种优异性能，能有效提高风电项目施工效率和保证风电机组长期的运行安全。
