北京混凝土无收缩防腐蚀预应力[孔道压浆剂] 制造商 孔道压浆剂河北总销售
预应力混凝土无收缩防腐蚀预应力孔道压浆剂是一种粉状的添加剂,当以一定的比例(占水泥掺量10%)添加在水泥之中,加水混合会形成一种具有收缩补偿性的,触变性的注浆液。该添加剂也有高效减水性、防腐性、膨胀性、阻锈性等的效果,使水与水泥之比控制在0.30左右,灌浆后获得很高的强度。
孔道压浆剂
    孔道压浆剂工法施工中,如何使套管压浆密实、不分层、强度均匀,钢铰线不锈蚀、预应力损失小,是近年来桥梁等结构工程使用100年以上必须考虑的问题。在欧洲,因采用铝粉作膨胀源、套管压浆不密实、强度下降等因素曾导致三座桥梁倒塌,两座是英国的Bickton Meadoms桥和Ynysy Gwas桥,另一座是比利时的Schelde桥。我国广东某斜拉桥拉索钢丝被严重腐蚀,以致需全部更换。在我国众多桥梁中,因压浆质量问题造成管内钢绞线严重腐蚀预应力损失大,导致安全隐患,甚至个别桥梁发生倒塌事件。因此,提高我国后张法预应力套管压浆材料的质量,确保预应力桥梁的安全使用期,必须引起高度重视。
    中国建筑材料科学研总院开发的孔道压浆剂套管压浆剂及压浆料,是以钙矾石 (C3A. 3CaSO4 .32H2O) 结晶体为膨胀源,并辅以无机和有机组分,压浆后不分层、不泌水,强度均匀,体积膨胀稳定,粘结力强,对钢筋不锈蚀,保证套管压浆质量,是代表国内最先进技术水泥基压浆材料。
产品分类 
    孔道压浆剂以 10% 左右掺入普通水泥拌制成的微膨胀灌浆材料,与普通水泥灌浆料相比,具有流动性好,不泌水、不分层,、压浆饱满早强、微膨胀等特性,并可一次性压浆施工,孔道内浆体密实无孔隙,预应力钢筋不锈蚀,与混凝土粘结牢固。  孔道压浆剂选用优质普通硅酸盐水泥 42.5 与灌浆剂复合而成,现场只需加水搅拌即可使用。套管压浆料减少了压浆剂现场复配水泥的施工工序,尤其是避免了压浆剂与不同水泥间的适应性所产生的问题。适用于后张法预应力孔道等其他需要高流动性的小缝隙粘结与填充压浆。
技术指标
    稠度按JTJ041-2000《公路桥涵施工技术规范》附录G-11“水泥浆稠度试验”方法试验,以水泥浆在14~18s全部流完时的水灰比,作为拌制预应力套管灌浆料的水灰比。水泥浆的泌水率根据JTJ041-2000《公路桥涵施工技术规范》附录G-10“水泥浆泌水率试验”检测;水泥浆强度、凝结时间参照GB/T17671-1999《水泥胶砂强度检验方法(ISO法)》检测;水泥浆膨胀率按《水泥基灌浆材料》JC/T986-2005检测:

使用方法
1.预应力筋的制作,锚具、夹具等的安装,预应力的施加,压浆等应满足设计要求,并符合JTJ041-2000《公路桥汉施工技术规范》第十二章的规定。 
2.压浆剂以10%(外掺)掺入P.O42.5水泥中,混合均匀。压浆料直接加水使用。
3.拌制预应力套管压浆料水泥浆的参考水灰比为0.38,实际加水量以浆体流动度为准。
4.预应力套管压浆料、水称量准确,并严格按确定的水灰比加水,不得随意调整加水量。
预应力混凝土无收缩防腐蚀预应力孔道压浆剂适用范围:
预应力混凝土无收缩防腐蚀预应力孔道压浆剂可用于预应力桥梁孔道的锚固和灌浆,防止地下水腐蚀钢筋(如石头锚固)和钢绞线(如预拉钢缆)。由于预应力混凝土无收缩防腐蚀预应力孔道压浆剂的触变性,更适应于离地面的灌浆。从应用上分有锚杆和钢绞线的预灌浆和后灌浆。
