Description

一种超高强砂浆的制备方法
技术领域
本发明属于建筑材料技术领域，涉及一种超高强砂浆的制备方法。
背景技术
一些工程建筑、特别是侵蚀环境的建筑，如化工厂、食品加工厂、冷库、重型机器厂等建筑物的地面以及港口和海洋平台、放射性废弃物储存容器等的建造，需要大量成本较低、可在施工现场制备的超高强砂浆。
现有的国内外超高强砂浆的配制，大多是采用磨细波特兰水泥、超细颗粒的硅灰(或矿渣、粉煤灰等)、精细石英砂(或其它优质细集料，如不锈钢粉)、水和超塑化剂等组成，成型时通过施加一定的压力后于室温静置1天后拆模，使用80℃或以上的热水浴养护一天后室温养护几天，再在高温(200℃左右)干热养护1天后冷却至室温养护到龄期，抗压强度达150兆帕以上。该技术配制的砂浆虽然强度高，但成本高、工艺复杂，不适合工程应用，目前仅限于制造某些工具、热塑性树脂的模具等预制品。
文献“Tensile properties of fibre-reforced very high strength DSPmortar(Magzine of Concrete Research，2000，52，No.2，Apr.，101～108)”叙述的一种超高强砂浆的配制，在工艺上进行了改进，其材料由比表面积为400～450m2/kg的白波特兰水泥、硅灰、粉状超塑化剂、精细石英砂、水组成，搅拌均匀后在75赫兹振动台振动成型，24小时拆模后80℃热水浴养护24小时，再在试验室条件养护到龄期，制得75mm×150mm圆柱体最小抗压强度为150兆帕。该方法成本仍高、工艺较复杂，在施工现场还是难以实现；由于国内最好的标号为62.5的水泥比表面积也只能达到380.6m2/kg，该砂浆的制备还需要进口水泥。
由于现有技术在施工现场制备超高强砂浆的困难，目前建筑用的混凝土材料强度低、密实度小，用于一些需要超高强高密实材料的工程建筑并不理想。
发明内容
本发明的目的，在于提供一种超高强砂浆的制备方法，这种砂浆成本低廉，便于施工现场制备，其强度可达到140-150兆帕(MPa)，能满足各种需要超高强高密实材料的工程建筑。
一种超高强砂浆的制备方法，其特征在于原料为水泥、硅灰、硅砂、石英砂、消泡剂、水和减水剂，其各组分的质量百分比为：水泥35％～50％，硅灰5％～15％，硅砂25％～35％，石英砂3％～10％，消泡剂0.1％～0.2％，水7％～14％，减水剂为水泥和硅灰(即胶凝材料)质量之和的1.5％～4.5％，各组份总量满足100％；
上述材料中，水泥为标号62.5、62.5R、52.5、52.5R的硅酸盐水泥，硅砂的细度为20～40目，石英砂的细度为100～200目，消泡剂为磷酸三酊酯或SP-202系列水性用消泡剂，减水剂为聚羧酸盐减水剂；
搅拌制作该超高强砂浆的方法为：采用变速搅拌机，在80转/分～350转/分范围内逐档提升搅拌速度，搅拌时间为10至25分钟，将搅拌好的砂浆倒入模具中，置于振动台上或插入振捣棒振动2～10分钟；养护方法为：在工地现场施工时，采用现有的高性能混凝土养护方法，即前3天每1-2小时浇水后覆膜，3天后每天早晚浇水后覆膜到龄期；在实验室制作时，覆膜约24小时后拆模，放入常温水中养护到龄期。
采用建筑行业制作混凝土或砂浆常用的振动台或振捣棒，振动频率国内一般采用50赫兹；在工地现场施工，模具较大或无法移动时，可采用振捣棒振动。
已有技术采用高温养护，是为了促进火山灰效应，从而提高强度。考虑到现场实施困难，本发明着眼于搅拌工艺，改进以往只是在宏观水平上达到均匀的搅拌，采用变速搅拌机，逐档增速，通过高速搅拌达到微观水平的均匀，促进了水泥的水化程度，从而提高了强度，实现了用常规养护方法养护制备超高强砂浆。
本发明的砂浆标准件按GB/T 50081-2002第六章进行立方体抗压强度实验，强度能达到140-150Mpa，密度约2.4克/厘米3。
除了硅酸盐水泥外，也可以采用相同标号(即相同强度)的普通硅酸盐水泥、矿渣硅酸盐水泥、火山灰质硅酸盐水泥、粉煤灰硅酸盐水泥、复合硅酸盐水泥等其他种类水泥制作本发明的超高强砂浆，这些水泥的主要成份同样为硅酸盐水泥熟料。采用其他种类水泥时，可以参照本发明的硅酸盐水泥质量百分比，以及该种类水泥中其他矿物混合材料的掺量，确定该种类水泥在砂浆中的质量百分比。
本发明具有以下优点：
1、流动性好，无裂纹、气孔少且小，内部结构致密，成型表面光滑，强度高，其强度/密度的值与钢的相当，具有较好的抗渗性和抗磨性。
2、所选材料为大量生产的市售产品，原材料易得。
3、相对于其他超高强砂浆，本发明的制备工艺简单并易于在工程施工现场实现，适合于工程化。
