Reynolds Number

The Reynolds number is a dimensionless quantity used to predict the behavior of a fluid flow and plays an important role when observing moving fluids. Flow properties such as Laminar and Turbulent are expressed as Reynolds numbers. The formula for calculating the Reynolds number for any fluid flow is: The Reynolds number is the ratio … Read more

Built Environment

The term “built environment” refers to aspects of the man-made environment that differ from the natural environment. This includes not only buildings, but also artificial spaces between buildings such as parks and infrastructure that support human activities such as transportation networks, utilities, flood protection, and communications. The built environment is also called the created environment. … Read more

Longitudinal Skin Reinforcement 

Longitudinal skin reinforcement is deformed rebar, wire, or bonded prestressed reinforcing bars evenly placed on either side of the vertical surface of the tensile region in a relatively deep beam to control the width of the crack. If the deep beam is not provided with such reinforcement, the crack width in the web will be … Read more

Planned Preventive Maintenance of Buildings

Planned preventive maintenance of buildings is a type of predictive or predictive maintenance that is a systematic approach to keep a building running or extending its life of a building before disturbance or failure occurs. Preventive actions can be planned or unscheduled. However, when it comes to building maintenance, planned preventive maintenance is the most … Read more

Rapid Hardening Cement

Rapid hardening cement is a special type of cement that achieves high strength in a shorter time. In general, the strength achieved by ordinary cement in 7 days is equal to the strength achieved in 3 days. This type of cement is also called High-Early Strength Portland Cement. This article describes the manufacturing process, properties, … Read more
