ABSTRACT: The construction industry constantly seeks innovative solutions to enhance the performance and durability of building materials. In recent years, nanotechnology has emerged as a promising avenue for improving the properties of cement-based materials, such as mortar (Mehta & Monteiro, 2016). The incorporation of Nano-sized Supplementary Cementitious Materials (SCMs) into mortar mixes has shown significant potential to enhance mechanical properties, particularly compressive strength. SCMs, such as silica fume, fly ash, and ground granulated blast furnace slag, have been traditionally used to improve the workability, durability, and environmental sustainability of concrete.

ABSTRACT The delay in project execution is a major problem in the Nigerian Construction Industry. This occurs both in small and large projects. Virtually a great percentage of the construction projects executed over the years across the country were faced with problem of delivery. Another noted problem in this industry is an issue of cost overrun, with attendant consequence of completing projects at higher sum than the initial sum. Therefore working with realistic project estimate is necessary at the outset of a project work which would eliminate uncertainty and as well as provide a platform for project success. This study is to examine procurement systems and it impact on cost managem... Continue Reading
