Concrete Core - an overview ScienceDirect Topics

The core contained 47 steel columns from the bedrock to the top of each tower.The size of the core columns at lower levels are 558 mm by 1371 mm steel box columns which are reduced to 406 mm × 914 mm box columns at the upper third levels.Concrete Cover Specifications for Reinforcement in Jan 11,2018·Concrete cover is assumed to be the first measure considered to prevent influences of aggressive elements on the reinforcement steel bars.That is why utmost cautions are needed during concrete cover thickness design and its construction.Commonly,the thickness of concrete cover is specified based on the type of the reinforced concreteConcrete Frame Structures - Understand Building ConstructionA standard mix may also specify the maximum aggregate size.Aggregates are the stone chips used in concrete.If an engineer specifies M30 / 20 concrete,he wants M30 concrete with a maximum aggregate size of 20mm.He does NOT want concrete with a strength of between 20-30 n/mm2,which is a common misinterpretation in some parts of the world.
