Abstract

Abstract: The investigates is basically on the Rheological and Mechanical properties of standard concrete by using Locally available Calcareous and Siliceous material and a comparative study is done for the rheological parameter for mixes with or without using superplasticizer. For rheological parameter, various mixes with water cement ratio of 0.45 and slump value of 120 mm were prepared for the experiment by replacing different percent as (0%,5%,10%,15%) of locally available material such as Metakaolin and tested with German based instrument ICAR Rheometer. Test on Rheometer is done to study flow property of concrete so that concrete mixes can be pumped to high rise building properly. As per the finding, as the metakaolin percentage were increased the static yield and dynamic yield stress decreases this indicate that it is easy to pump at higher blending. For mechanical properties, mixes were prepared and test Performed is compressive strength test. The findings of this experiment have important implication for construction industry basically in the high-rise structure
利用当地的石灰质和硅质材料制作标准混凝土的流变学和力学性能
摘要:研究的主要内容是利用当地可获得的石灰质和硅质材料对标准混凝土的流变学和机械性能进行研究,并对使用或不使用超塑化剂的混合料的流变学参数进行比较研究。在流变参数方面,实验中通过添加不同比例(0%、5%、10%、15%)的当地材料(如偏高岭土),制备了水灰比为 0.45、坍落度值为 120 毫米的各种混合料,并使用德国仪器 ICAR 流变仪进行了测试。流变仪测试的目的是研究混凝土的流动性能,以便将混凝土拌合物正确地泵送到高层建筑中。结果表明,随着偏高岭土比例的增加,静态屈服应力和动态屈服应力都有所降低,这表明掺量越高,混凝土越容易泵送。在机械性能方面,我们制备了混合料,并进行了抗压强度测试。本实验的结果对建筑行业(主要是高层建筑)具有重要意义。
