Plastic waste (PW) has received a lot of attention as a possible additional material for industrial and environmental applications, particularly cement and/or concrete production for a more environmentally and economically sound use of raw materials and energy sources. PW has been investigated as an inert and/or active hydraulic filler for cement and/or concrete by numerous scientists. Plastic garbage is cheap, abundant, and takes long period of time to degrade in the eco-system (soil and water). The main goal of the ongoing research is to offer safety and efficacy by partially substituting nano-plastic waste (NPW), incorporated with nano-titania (NT), for the composition of white cement (WC). Blends are built up by substitution of WC with different ratios of NPW incorporated with fixed ratios of nano-titania (1.0 wt.%). Workability, physical, mechanical and microstructural properties have gone through laboratory and instrumental analysis. The results showed improvement in the compressive strength, density and microstructure due to the effective impact of fillers. Consequently, a decrease in total porosity, whiteness reflection (Ry) and early-rapid expansion. Eventually, the outcomes may reduce the pandemic strength, especially in the external environment, and other epidemics.
塑料废料（PW）作为一种可能用于工业和环境应用的额外材料受到了广泛关注，特别是在水泥和/或混凝土生产中，以更环保、经济地使用原材料和能源。许多科学家已将PW作为水泥和/或混凝土的惰性和/或活性水硬性填料进行了研究。塑料垃圾价格低廉、数量丰富，且在生态系统（土壤和水）中需要很长时间才能降解。正在进行的研究的主要目标是，通过用与纳米二氧化钛（NT）混合的纳米塑料废料（NPW）部分替代白色水泥（WC）的成分，来提供安全性和有效性。通过用不同比例的与固定比例纳米二氧化钛（1.0重量%）混合的NPW替代WC来制备混合物。对工作性、物理、力学和微观结构性能进行了实验室和仪器分析。结果表明，由于填料的有效作用，抗压强度、密度和微观结构得到了改善。因此，总孔隙率、白度反射率（Ry）和早期快速膨胀有所降低。最终，这些结果可能会降低疫情强度，尤其是在外部环境及其他流行病方面。
