Diamond was known to be the hardest material found on planet earth but not any more. A group of scientists have discovered a new form of carbon which they say is...

Why SRMs Are Added In Concrete SRMs (Secondary Raw Materials) or SCMs (Secondary Cementitous materials) are added to concrete systems mostly in replacement mode ( They replace a part of cement ). If...

Definition ACI 237 defines Self Compacting Concrete (SCC) as "highly flowable, non-segregating concrete that can spread into place, fill the formwork, encapsulate the reinforcement without any mechanical consolidation. Idea Of Self Compacting Concrete SCC...

Concrete Mix design is complete science and it is based on a lot of research. Popular Mix Design method is highlighted in ACI 2011 committee report. It is a systematic approach...

We all know cracking is one of the major problems in concrete and it should be considered while mix design, but for that, we have to know the sources which can...
Light Gauge Steel Construction

Back Ground The construction industry is looking for safe, innovative and improved construction materials and methods for the construction of office, residential and other structures. Construction industry is increasingly demanding for advances...

  Spalling Spalling is considered as one of the most complex and poorly understood phenomenon occurred at high temperatures. (Khoury 2000; Tenchev and Purnell 2005) Mostly it is assumed that this phenomenon occur...

What Is Segregation? Segregation refers to separation of different concrete phases. It happens when concrete mix is not cohesive enough. Slump Test in Conventional concrete and Flow test in Self Compacting Concrete can...

This video (at the end) explains the production of a prestressed concrete unit (Double T) on a prestressing concrete plant. Double T is a versatile prestressing unit which are mostly used in parking...
