Cement is a vital material in our modern society. It is the only thing that humans consume more of, by volume, than water. Conventional cement-based materials are usually brittle, have low tensile strength and exhibit bulk shrinkage. Due to the recent advancements in nanotechnology, many researchers investigated the addition of nanoparticles to the cement mix to enhance its workability and mechanical properties. In fact, nanoparticles were found to increase compressive and tensile strengths and decrease porosity and permeability of the cement. However, on top of the high cost of the commercially available nanoparticles, proper dispersion of the nanoparticles within the cement slurry was a challenge. This work aims to fabricate the nanoparticles within the cement slurry by utilizing inexpensive materials to formulate the nanoparticles. The study focuses on cementing applications in the oil and gas industry, but the methodology can also be applied to the construction industry. The potential impact of this work is huge through providing better protection for the environment and reducing cement requirements in various applications. Hence, lower CO2 emissions from cement manufacturing and lower construction cost.

水泥是我们现代社会中的重要材料。这是人类唯一比水消耗更多的东西。常规的基于水泥的材料通常是脆性的，具有低拉伸强度，并且表现出大量收缩。由于纳米技术的最新进展，许多研究人员研究了在水泥混合物中添加纳米颗粒，以增强其可行性和机械性能。实际上，发现纳米颗粒会增加压缩和拉伸强度，并降低水泥的孔隙度和渗透率。但是，除了商业上可获得的纳米颗粒的高成本外，水泥浆中纳米颗粒的适当分散是一个挑战。这项工作旨在通过利用便宜的材料制定纳米颗粒来制造水泥浆中的纳米颗粒。该研究重点是巩固石油和天然气行业的应用，但该方法也可以应用于建筑行业。通过为环境提供更好的保护并减少各种应用中的水泥要求，这项工作的潜在影响是巨大的。因此，水泥制造和较低的建筑成本的二氧化碳排放较低。
