·Testing shows bacterial concrete has higher strength and crack healing ability compared to normal concrete While increasing durability applications in construction could lower costs and improve sustainability over time Further research is still needed to optimize the technology for practical and economic feasibility at scale Read less
·4 COMPOSITION For producing high density concrete it uses heavy natural aggregates such as barites or magnetite or manufactured aggregates such as iron or lead shot The density achieved will depend on type of aggregate used typically using barites the density will be in the range of 3500kg/m³ 45% greater while with magnetite the density will be
·6 USES OF CEMENT • Cement is used for the preparation of cement mortar cement concrete and reinforced cement concrete • Cement mortar is used for masonry work plastering and pointing • Cement concrete used in RCC for roof slabs columns water tanks dams foundations railway sleepers etc • Cement is used in the manufacture of dust bins

·This document discusses several topics related to advanced wireless technologies including Voice over IP networks VoIP vehicular networks and delay tolerant networks It provides overviews and definitions of each topic describing key aspects like VoIP architecture and protocols vehicular communication methods between vehicles and
·4 abStract Cracks in concrete are inevitable and are one of the inherent weaknesses of concrete Water and other salts seep through these cracks corrosion initiates and thus reduces the life of concrete So there was a need to develop an inherent biomaterial a self repairing material which can remediate the cracks and fissures in concrete Bacterial concrete
·10 Overview • Method of vertically extruding a reinforced concrete section and is suitable for construction of core walls in high rise structures lift shafts stair shafts towers • The formwork rises continuously at a rate of about 300 mm per hour supporting itself on the core and not relying on support or access from other parts of the building or permanent works
·The document discusses advanced building construction technology specifically portal frame structures It defines a portal frame as a continuous two dimensional frame with rigid joints between columns and beams Portal frames are commonly used for single story structures like warehouses The project background describes a steel rigid portal frame
