【摘要】 水泥混凝土是近现代最广泛使用的建筑材料,也是当前最大宗的人造石材。据不完全统计,世界水泥年产量已超过15亿吨,折合成混凝土,应不少于45亿立方米。与其它常用建筑材料(如钢材、木材、塑料等)相比,水泥混凝土生产能耗低、原料来源广、工艺简便,因而生产成本低;它还具有耐久、防火、适应性强、应用方便等特点。因此,在今后相当长的时间内,水泥混凝土仍将是应用最广、用量最大的建筑材料。对这样的大宗材料进行有效的研究开发,尤其是提高性能、降低成本、节约能耗,不断扩大其应用范围,具有重大意义。本文提出了用电液压脉冲强极性活化水来提高混凝土和砂浆的力学性能的新设想,较为系统地深刻分析了电液压脉冲制备强极性活化水的作用过程。在此基础上,本文从宏观和微观两个方面探讨了电液压脉冲强极性活化水提高混凝土性能的机理,给出了电液压脉冲强极性活化水提高混凝土力学性能的效果和影响因素。为了有效支持理论探讨,作者做了一些实验,实验结果表明:1、作者所提出的用强极性活化水提高混凝土的力学性能是可行的、效果是稳定的。虽然受实验条件所限,作者未能做大量的实验并进行全面的分析,但所有实验数据都显示出电液压脉冲方法能提高混凝土的抗压强度;2、利用强极性活化水搅拌混凝土,在节约水泥量达10%的情况下,其抗压强度仍有一定程度的提高。同时,通过实验结果可以看出,电液压脉冲的不同电气参数对混凝土力学性能的提高效果有较大影响,这些参数包括放电能量、放电次数、电极极间距离等。
【Abstract】 Currently, concrete is one kind of construction materials which is used extensively. It is reported that the yield of cement per year over the world has surpassed 1.5 billion tons. And the yield of concrete adds up to 4.5 billion cubic meters per year. Conparing with other construction materials, concrete has many merits, for example, it is endurable, convenient, and so on. With these merits, we can sure that exploring a feasible method to generate high performance concrete is valuable.A good idea, using strongly polar activated water produced by Electro-hydraulic Impulse Technology to improve the mechanical performance of concrete, is put forward in this dissertation. The process of generating strongly polar activated water is described in this paper. On the basis of the work, the mechanism of strongly polar activated water improving the mechanical performance of concrete is analyzed from the aspects of macroscopic and microscopic view. Then, the effects of improvement and the optimum parameters are provided. In order to support the theory discussed above, some experiments are done. The results of the experiments indicate that using strongly polar activated water to improve the mechanical performance of the concrete is practical and feasible. And with the strongly polar activated water, even the amount of cement ia decreased to 10 percent, the mechanical performance of the concrete is improved too. Of course, the increase rate is different with different parameters, these parameters include discharging energy, discharging times, the distance between the two electrods, and so on.
