Fiber Reinforced Concrete: [caption id="attachment_1544" align="aligncenter" width="300"] Steel Fiber Reinforced Concrete.[/caption] Due to the presence of microcracks at the interface of mortar-aggregate, plain concrete is considered as a brittle material. It ...

Workability Of Concrete: Workability can be defined as the property of fresh concrete which describes the ease and homogeneity of the concrete to be mixed, fully compacted and finished. A workable concrete should possess following two requirements: 1. The concrete ...

Common Concrete Problems And Their Prevention: There are many problems we might be facing during and after concreting. To produce high quality concrete we must take some precautions to avoid those common problems during concreting. In this article, we ...

Quality Control Of Concrete: Concrete is mainly prepared at the construction site using locally accessible materials of variable properties. Hence the concrete strength differs from one batch to another batch over a time period. The variation in concrete strength ...

Workability Of Fresh Concrete By Compaction Factor Test: [caption id="attachment_1323" align="aligncenter" width="300"] Compaction Factor Test Machine[/caption] Theory: The compaction factor test is carried out to measure the degree of workability ...

Waterproofing Of Concrete: A concrete is said to be well designed when it is properly mixed, compacted, cured and set for making impermeable itself. The uses of waterproofing agents should be kept away as much as possible for working ...

Different Sources Of Cracks In Concrete: Cracking is one of the most common problems in concrete and it should be avoided seriously. Different causes of cracks in concrete are described below. 1. Shrinkage: Shrinkage is one of the major ...
