In this article we demonstrated the study results of durability quality of cement paste containing waste solar PV cells. The conclusions were made on effect of this cement replacement. The use of ground solar cells on the durability properties of cement-based composite was investigated. As a result, we identified the factors affecting the durability for those of cement mortar specimens which predefined and made in lab.

Strength And Durability

The nanotechnology provides an impact on construction industry materials with new properties and produce material with better performance. This paper presents the experimental investigation on the effects of nano particles incorporated in the cementitious materials to study the strength and durability properties of cement mortar. Nano particles such as nano alumina (NA), nano ferric oxide (NF) and nano silica (NS) were mixed at different proportions of 0.5%, 1% and 1.5% by weight of binder in single and binary combinations. Mechanical properties such as compressive strength and split tensile strength; durability properties such as water absorption and rapid chloride permeability test were tested as per standards. The results showed that 1.5% of the combination of nano silica & nano ferric oxide (NSF) and nano silica & nano alumina (NSA) particles increased the mechanical strength and durability properties of cement mortar. The microstructure characteristics results revealed that the nano particles incorporated cementitious materials showed the voids were filled up with nano particles. It acts as filler in cement mortar that enhanced a dense microstructure, reduced the quantity and size of calcium hydroxide and also filled the voids of C-S-H gel structure.

Nanosilica Particle

This work presents the effect of nanosilica particle sizes on durability properties and repair work properties of cement mortar containing nanosilica (NS). Three different NS particle sizes of 12, 20, and 40 nm were used and compared with those of cement mortar without NS and cement mortar with silica fume (SF). Interesting results were obtained in which the particle size of NS affected directly the abrasion resistance and water permeability. NS with particle size of 40 nm is the optimum size and gave the highest abrasion resistance and water permeability. For repair work properties, cement mortars containing NS (12 and 20 nm) and SF experienced higher drying shrinkage than that of cement mortar without NS and then presented cracking behavior and debonding between the cement mortars and concrete substrate. Cement mortar containing 40 nm of NS gave the lowest drying shrinkage, the lowest crack number, and the highest adhesive strength. These results indicate that the particle size of NS affected not only the durability properties but also the repair work properties of cement mortar.
