| 摘 要： | 利用天然硬石膏为主要原料,通过掺加激发剂、减水剂、保水剂、掺合料、骨科、纤维和减缩剂等进行改性处理,研制成功了一种天然硬石膏自流平抗裂砂浆;流动度达到150mm以上,抗压、抗折强度分别达到28MPa和9MPa,粘结强度达1.2MPa,主要技术性能指标均达到或超过JC/T 985-2005地面用水泥基自流平砂浆标准要求,同时还进行的材料抗裂性能研究,极大地改善了材料的抗裂性能.试验表明,天然硬石膏自流平抗裂砂浆流动性好、平整度高、凝结快速、强度高、抗裂性好,是一种理想的石膏基自流平地面材料,值得推广应用.

| Abstract: | A new kind of natural anhydrite-based self-leveling and anti-crack mortar with fi ne fluidity, high planenes, fast concreting, high strength and good water tolerance, has been developed with anhydrite powder by mixing seemly excitant, water reducing agent, water retention agent additive and aggregate. The test results showed that the main performance indexes of this material have all reached or exceeded the requirements of the standard of JC/T 985-2005,such as fluidity was more than 150mm, compressive stren... |
