Description

一种快速高强度机场道路专用修补砂浆
技术领域
本发明涉及建筑材料领域，尤其是涉及一种快速高强度机场道路专用修补砂浆。
背景技术
机场道路一般要求较高的强度，并且在修补时需要能够快速成型，而现有的同类砂浆中，普遍流动性差，人工操性不强，干燥成型速度慢，并且承受强度小，并且28d时有收缩现象，长时间使用仍会致裂。
发明内容
为解决现有技术中的问题，本发明提出了一种快速高强度机场道路专用修补砂浆，钢纤维10％-20％、级配砂30％-50％、乳胶粉1％-5％、水泥1.4％-39.7％、膨胀剂3％-7％、钠米微硅粉3％-7％、四硼酸钠0.1％-0.5％、超早强剂0.1％-0.6％、羧酸减水剂3％-8％、消泡剂0.1％-0.5％。
优选的，钢纤维15％-18％、级配砂35％-45％、乳胶粉2％-4％、水泥12.5％-36％、膨胀剂3％-6％、钠米微硅粉4％-6％、四硼酸钠0.3％-0.4％、超早强剂0.4％-0.6％、羧酸减水剂4％-7％、消泡剂0.3％-0.5％。
优选的，所述级配砂粒径为0-2.5mm。
本发明提出的快速高强度机场道路专用修补砂浆有以下有益效果：常温20度左右，施工完成后4h后可通车，3h抗压强度可达30MPa，28d抗压强度可达70MPa近80MPa不收缩有微膨胀性，施工性、短时强度、高于同类砂浆，无收缩、抗裂性和冲击韧性更优于同类修补砂浆。
具体实施方式
下面结合具体实施方式，进一步阐明本发明。
实施例1
本发明提出了一种快速高强度机场道路专用修补砂浆，一种快速高强度机场道路专用修补砂浆，钢纤维10％、级配砂30％、乳胶粉1％、水泥1.4％、膨胀剂3％、钠米微硅粉3％、四硼酸钠0.1％、超早强剂0.1％、羧酸减水剂3％、消泡剂0.1％。
优选的，所述级配砂粒径为0-2.5mm。
实施例2
本发明提出了一种快速高强度机场道路专用修补砂浆，钢纤维20％、级配砂50％、乳胶粉5％、水泥39.7％、膨胀剂7％、钠米微硅粉7％、四硼酸钠0.5％、超早强剂0.6％、羧酸减水剂8％、消泡剂0.5％。
优选的，所述级配砂粒径为0-2.5mm。
实施例3
本发明提出了一种快速高强度机场道路专用修补砂浆，钢纤维15％、级配砂40％、乳胶粉4％、水泥22.6％、膨胀剂5％、钠米微硅粉6％、四硼酸钠0.5％、超早强剂0.5％、羧酸减水剂6％、消泡剂0.4％。
优选的，所述级配砂粒径为0-2.5mm。
因砂浆在此处用于地铁管片用和特殊用处的不规则弧面修补，要非常好的可塑形性能和抹灰不流挂性能，为了描述施工和易性，我们将其分为四级：
优--粘度适中、不规则塑形性好、抹灰不流挂不粘刀
良--粘度稍大、不规则塑形性好、抹灰不流挂有粘刀
中--粘度稍大、不规则塑形性一般、抹灰不流挂有粘刀
差--粘度稍大、不规则塑形性一般、抹灰有流挂有粘刀
对实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
