Abstract

Abstract. The process of construction begins some thousand years ago and the monuments that we are seeing are the proof for that. The materials that are being used in the construction some thousand years ago are not the same which are being used nowadays. The construction materials get modified and new inventions are taking place due to the continuous research. The scope of this project is to make building materials sustainable and to make them eco-friendly. In the olden days lime was used as a mortar and now it’s being replaced by cement. But still research is going on to make better binding materials to make construction reliable. As an initiative, in our project we are going to partially replace cement with metakaoline, fly ash and silica fume simultaneously. We are going to replace cement with each additive in the order of 5%, 7.5%, 10%, 12.5%, and 15%. Therefore, the summation of replacement of all additives will be in the order of 15%, 22.5%, 30%, 37.5%, 45%. The concrete specimens are casted based on the replacement ratios along with the conventional concrete specimens. The specimens are subjected to the various laboratory tests and it was found that a 10% replacement of cement with additive materials to be optimum.

偏高岭土、粉煤灰、硅灰在混凝土中部分替代水泥的试验研究

摘要建筑的过程开始于几千年前，我们所看到的纪念碑就是证据。几千年前建筑中使用的材料和现在使用的不一样。由于不断的研究，建筑材料得到了改进，新的发明也不断出现。这个项目的范围是使建筑材料可持续发展，使其环保。过去石灰被用作砂浆，现在正被水泥所取代。但研究仍在继续，以制造更好的粘合材料，使建筑更加可靠。作为一项倡议，在我们的项目中，我们将同时用偏高岭土、粉煤灰和硅灰部分替代水泥。我们将按照5%、7.5%、10%、12.5%、15%的顺序替换水泥。因此，所有添加剂的替换量之和将依次为15%、22.5%、30%、37.5%、45%。在常规混凝土试件的基础上，按置换比浇筑混凝土试件。对试件进行了各种实验室试验，发现用添加剂材料替代10%的水泥是最佳的。
