In this review article ,we will appraise existing, relevant literature documenting investigations conducted by other researchers. The review will evaluate the methodology used in the other previous work as well as highlight the major findings of their investigations. By reviewing what other researchers have done with regard to the development of solar concrete connectors, in this study there was an ability to identify research gaps achieved by experimental experiments of this research stream seeking to fill. The following paragraphs summarize the most relevant scientific works that the study was able to review.The literature was reviewed in a chronological order just to capture the developments and advancements that have been realized over the years.

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.
