On creating optimal working conditions in multi-storey buildings of concrete mixing plants

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Critical Points of Prefabricated Reinforced Concrete Wall Systems of Multi-storey Buildings

With respect to the dissipation of energy through plastic deformation of joints of prefabricated wall units, the paper points out the principal importance of efficient reinforcement of the prefabricated system at its joints. The method, quality and amount of reinforcement are essential for reaching the necessary degree of joint ductility. The paper presents partial results of experimental resea...

On-site greywater treatment and reuse in multi-storey buildings.

The paper presents a study of a pilot plant treating light greywater for seven flats. The pilot plant combines biological treatment (RBC) with physicochemical treatment (sand filtration and disinfection). The pilot plant produced effluent of excellent quality, meeting the urban reuse quality regulations, and was very efficient in TSS turbidity and BOD removal: 82%, 98% and 96%, respectively. CO...

Atrium-assisted Natural Ventilation of Multi-storey Buildings

Buoyancy-driven displacement natural ventilation in a simple multi-storey building structure is investigated. The storeys are connected to a common atrium and top-down-chimneys, and the internal heat gains of the storeys are represented by localised point heat sources on each floor. The heat sources generate thermal plumes which entrain the surrounding air and transport warm air upwards. Simple...
