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.

水泥是现代社会的重要材料。按体积计算，水是人类消耗的唯一比水多的东西。传统的水泥基材料通常是脆性的，抗拉强度低，并表现出体积收缩。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加入纳米颗粒以提高其和易性和力学性能。事实上，纳米颗粒可以提高水泥的抗压和抗拉强度，降低水泥的孔隙度和渗透率。然而，除了商用纳米颗粒的高成本之外，纳米颗粒在水泥浆中的适当分散也是一个挑战。本研究旨在利用廉价材料在水泥浆中制备纳米颗粒。该研究侧重于固井在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。这项工作的潜在影响是巨大的，可以更好地保护环境，减少各种应用对水泥的需求。因此，水泥制造的二氧化碳排放量更低，施工成本也更低。
