高强抗裂防水宝采用美国进口以火山灰熔岩煅烧物和石灰石、适量石膏及化工填料共同磨细而成，具有快硬、早强、高强、膨胀、及抗硫酸盐侵蚀性能的水硬性胶凝材料，国内xx。
Crack use of high-strength waterproof treasure imports to the United States of lava ash calcined material and limestone, gypsum and chemical fillers suitable co-grinded made, with rapid hardening, early strength, high strength, expansion, and sulfate resistance of the cement matrix domestic initiative.
一.主要性能：
ONE. Key Features:
1）早强、高强：{yt}抗压达到36 Mpa -55Mpa，随着养护龄期的增长强度还不断增长。
1) The early strength, high strength: one day compressive strength reached 36
Mpa-55Mpa, with the intensity of curing period of growth is also growing.
2）高抗冻性能：适于低温环境施工，即使轻微受冻强度也几无损失，强度仍能达到普通硅酸盐水泥的5倍。
2) high frost resistance: suitable for low-temperature environment, construction, and even a slight cold and almost no loss of intensity, the intensity could meet 5 times the ordinary Portland cement.
3）高抗渗性：防水宝结构致密，抗渗性是水泥的3-5倍。
3) High impermeability: waterproof Po compact structure, impermeability is 3-5 times that of cement.
4）微膨胀性：四个月的干缩率为零。抗
