阻泥剂
       阻泥剂是─种新型混凝土外加剂。属于小分子吸附剂,可以优先吸附在粘土颗粒表面,中和粘土的电荷,降低粘土对聚羧酸减水剂的吸附。不易燃,无锈蚀作用,可广泛应用于建筑、道路、桥梁、水工和地下工程等各类泵送施工的混凝土。       作用︰       1.有效降低泥和石粉对外加剂的吸附,增加混凝土的流动性和扩展度。       2.可以降低混凝土的坍落度经时损失。       使用方法∶当泵送剂的掺量为1.5-3.0%时,根据混凝土的和易性要求,加入5-8Kg,可以有效的改善混凝土离析、泌水的现象。       说明︰避光、防潮、密封置干燥阴凉处,室温存放。       注意事项       每吨泵送剂中用量5-8公斤,不能超量使用。​​

03
使用混凝土保坍剂,如何解决加水离析?
      混凝土超掺就可能导致混凝土,具体的掺量是和保坍剂的品种,配合比的水灰比、用水量有关系,是不确定的。造成离析,一方面说明保坍剂可能多了,同时,用水量也相比较来说多了。      打个比方,你用保坍剂,推荐掺量C*2%,如果你仅仅掺1.8%,但是用水过多,同样离析。如果用水量不变,可能设计配合比增加掺量到3%以上才离析。当然,如果你掺加到4%左右,可能容易泌水、泛浆、气泡过多,、抓底等,这个掺量数值,也是和配比、原材料指标有关系的。每种保坍剂也不一样。一般情况下,都是比外加剂推荐掺量的上限高出一块的。具体的数值你只能试验得到。      这样离析的混凝土虽然水胶比没有变化,但是,强度还是受到一定影响的。      补救方法非常多      1缩小外加剂掺量      2引气剂是非常有效地减少了泌水的外加剂助剂,但是注意不能影响混凝土强度哦。      3降低用水量      4增加砂率      5增加胶凝材料等等。      6泌水也可通过适当的配比,均匀和完全混合可以减少混凝土泌水。      7利用细碎的火山灰材料通过增大胶材比较面积,使得水的路径更长,减少泌水。      8使用有保水的外加剂助剂,比如乐宝保坍剂,利用高分子聚合后整合混凝土排序,有效包裹混凝土,避免因材料变化与外加剂母液适应性问题导致的泌水情况,弥补外加剂的缺陷      泌水完全可以通过添加更细的水泥和含,低碱含量水泥,浆体更加均匀,充分的混合不太容易泌水。

02
混凝土减胶剂(增效剂)工作原理及添加使用方法
       减胶剂是一种由高分子表面活性剂组成的混凝土外加剂,也叫增效剂。通过改善混凝土和易性,提高混凝土整体浆量,从而减少水泥用量,并保证混凝土后期强度发展。在实际使用中,混凝土减胶剂的掺量一般为胶凝材料的0.6%,可与外加剂同掺(不能混合后使用,在减胶剂使用时并不减少减水剂用量)。目前,混凝土减胶剂在建筑、项目工程等应用较为广泛,可适用于自密实混凝土、大体积混凝土、低标号与高标号混凝土等。        混凝土减胶剂的作用机理是通过调节与控制水泥熟料各矿物的分散效果,实现水泥熟料的高效分散,减少矿物团聚现象的发生,提供颗粒水化环境,加速水泥水化进程,从而起到提高混凝土强度或降低单位混凝土水泥用量的效果。华轩高新生产的减胶剂可有效减少聚羧酸减水剂在熟料矿物中的插层吸附量,从而使其能够有效吸附与硅酸盐矿物中,从而进一步改善颗粒分散效果,凸显增强减水的效果。        华轩高新生产的减胶剂能够适应各种牌号聚羧酸减水剂,体现出较高的适应性。而且还能改善聚羧酸减水剂使用过程中出现的坍损快、离析、泌水等现象,有效控制高产量减水剂带来的负面效应。同时,还可提高混凝土密实度,从而提高其抗氯离子渗透性、抗碳化性、抗冻性能等耐久性指标。        现如今,市场上的水泥材料颗粒较细。在搅拌混凝土时,当水泥与水混合后,水泥颗粒在静电引力等作用下相互吸引,进而形成立体的三维絮凝结构。拌合水中约10%-30%被包裹在絮凝结构中不能自由流动而丧失了润滑作用,使得混凝土拌合物的流动性大大降低,而普通减水剂不能有效分散特细颗粒的絮凝结构。而据我们的研究发现,混凝土中添加适量减胶剂可有效分散这些絮凝结构,因而使水泥颗粒更充分地与水接触,提高其反应活性。而且,在实际应用中,减胶剂还可以充分活化具有潜在活性的矿物掺和料,从而提高胶凝材料的水化程度,达到提高混凝土强度或降低水泥用量的目的。

11
引气剂对混凝土的性能有什么影响?
       随着国家的发展,我们的硬件设施也是紧随其上,公路、桥梁的建设更是突飞猛进,在这些工程的施工过程中,会用到各种各样的建筑材料,目的只有一个就是让建筑更加的牢固,引气剂便是其中一种,今天我们就来了解一下它的作用吧!       引气剂是指在混凝土搅拌过程中,能引人大量均匀分布的微小气泡,以减少混凝土拌和物泌水、离析,改善和易性,并能显著提高硬化混凝土抗冻性、耐久性的外加剂。 引气剂对混凝土性能的影响:       (1)改善混凝土拌和物的和易性。引气剂引入的气泡具有滚珠作用,减小拌和物的摩擦阻力从而提高流动性;同时气泡的存在阻止固体颗粒的沉降和水分的上升,从而减少了拌和物分层、离析和泌水,使混凝土和易性得到明显改善。       (2)提高抗冻性和抗渗性。气泡可缓解水分结冰产生的冰胀应力,且气泡呈封闭状态,很难吸入水分。与普通混凝土中存在大而连通的孔隙相比,含冰量大为降低,所以抗冻融破坏能力得以成倍提高。另外,大量均匀分布的封闭气泡切断了渗水通道,提高了混凝土抗渗能力。       (3)降低强度及弹性模量。由于气泡的弹性变形,使混凝土弹性模量降低。另外,引气剂增加了混凝土的气泡,使得强度降低,但是由于和易性的改善,可以通过降低水灰比并维持原和易性,使强度不降低或部分补偿。
