Concrete defects Archives - Building Defect Analysis

15/01/2018  In particular, concrete framed buildings built from 1950s to the late 1960s had insufficient depth of concrete cover. It was not unusual for the reinforcement bars to corrode causing the covers to crack and detach over a period of time. It was particularly common in the 1950-1960s due to architects striving for an aesthetically pleasing property. West Midlands Projects. Recently we worked on a ...

Houses of Non-Traditional Construction – Common Property ...

20/03/2016  The primary concern in houses of concrete construction is carbonisation of the concrete, which can result in the reinforcing steels rusting, compromising the building’s structural integrity. Generally, carbonisation is a greater issue in buildings of precast reinforced concrete construction, due to the use of poor-quality concrete, and reinforcing steels being placed at insufficient depths ...

What Factors Causes Failure of Concrete Structures?

Poor compaction and inadequate preparation are common problems of joint construction. If such joints are not constructed properly, it would become a path for moisture to penetrate concrete. Grout leakage : When joints of formworks are not sealed properly, then grout and fine material would move out of concrete mixture. As a result, a considerably porous concrete will be produced. Poor ...

Precast Concrete: Advantages and Disadvantages

Precast concrete is a form of construction, where concrete is cast in a reusable mould or “form” which is then cured in a controlled environment, transported to the construction site and lifted into place. By producing precast concrete in a controlled environment (precast plant), the precast concrete is provides the opportunity to properly cure and be closely monitored by plant employees ...
