Since from the start the concrete has gone through several tests, experiments and additions in order to make it suitable for some specific situation and specific condition where normal concrete is not considered feasible or effective.
Admixtures are basically chemicals or compounds that are added in suitable proportion into the concrete in order to change and vary some specific property…
Ready mix concrete as the name suggest is the concrete that is already mixed in suitable proportions before arrival at site either on agitating trucks or dumpers as per the requirement of slump or material.
Basically the ready-mix concrete is mixture of binding agent…
Have you ever seen a façade or cladding giving look of a rock-hard material but still gives you a see-through and translucent look inside the building? .
The widest used construction material, which is sustainable and reliable as well, is getting a makeover by…
Fiberglass is basically a matrix in which very fine fibers of glass exists. Fiberglass material is usually used for making of boats or for temporary sheds like sometimes on the roof tarus. That is the reason where ever the word fiber glass is touched ones always thinks of it as insulation boards or boats etc. In fiber glass a reinforced plastic-glass polymer is mixed in a polymer and if instead of…
Quality of concrete depends on many factors among which the most vulnerable and defenseless is workmanship. During pouring the concrete and execution of work cautious supervision is imperative. The supervisor has to look for many things including the finishing of concrete…
1 | Pantheon, Romepossibly by Apollodorus of Damascus, c126 AD
The ancient Romans didn’t have reinforced concrete (that is, strengthened with steel) but they had concrete, and used it to such heart-stopping effect on the Pantheon that no one has really been able to…
The finishing in concrete works is vital as for sure the final touches depend on it. The poor finish of concrete is not only wrong from aesthetic point of view but also it shows the strength and integrity of the concrete structure. Besides many defects in concrete one important is honeycombing.
Hollow spaces and cavities left in concrete mass on surface or inside the concrete mass where…
The analysis and design of structures to resist the effect produced by time dependent forces or motions requires conceptual idealizations and simplifying assumptions through which the physical system is represented by an idealized system known as the analytical or…
Reinforcement in the form of steel or synthetic strips called geo-strips are placed within an embankment, containing soil in various layers compacted mechanically; the granular material of embankment is linked by means of friction. The embankment becomes a self supporting structure, such a structure is called reinforced earth structure.
Earth Reinforced with Geo-strips and Reinforced Earth…
Structural Concrete Slabs are constructed to provide flat surfaces, usually horizontal, in building floors, roofs, bridges, and other types of structures. The slab may be supported by walls, by reinforced concrete beams usually cast monolithically with the slab, by…
Cantilever Retaining wall is a reinforced cement concrete (RCC) Structure that is used to retain and hold back loose soil and gravel behind where there are abrupt changes in slope beyond their natural and stable angle of repose.
Complete Design of Cantilever Retaining…
We know that soil or any other loose granular material has a safe angle of repose at which the soil or material can withstand without any requirement of confinement or support. But due to practical and property restrictions we in some cases need to cut or fill the soil at some unstable angle which if unsupported might cause failure of the slope.
Concrete Retaining Wall
If we provide…

Reinforced Concrete Structures are widely being constructed throughout the world and because of availability of raw materials required to design a mix, they lead other building materials like wood, stones etc. Mostly the code and guidelines used to design reinforced concrete…

In this post I will be sharing with you a very famous and useful book titled with “Design of Concrete Structures”. This book is mostly used as a text book in many institutions for the subjected of Reinforced Cement Concrete. The book is written in simple…
How many times as a civil engineer, you have to test a concrete? Hunh! So many Times! But most of the time you find concrete cubes and cylinders being crushed by Compression Testing Machine (CTM) in the laboratory. Now that broken cylinder or cube is useless for you, although you can recycle it but even then a recycled material can never meet the standard of first class material. Think about…
