Coefficient of Thermal Expansion of Concrete

Coefficient of thermal expansion is defined as the change in unit length per degree of temperature change. In a concrete element,...

Restraint and Restraint Factors of Concrete

If movement (expansion and/or contraction) is restricted within a young concrete element, tensile stresses will develop which will lead to cracking....

Cracking in Concrete

Eurocode recognises that cracking is normal in concrete subjected to bending, shear, torsion, and restraint from movement (clause 7.3.1 EN 1992...

Crack Width and Crack Spacing Calculation in Concrete

Cracking occurs in concrete when the restrained strain exceeds the tensile strain capacity of the concrete. In critical elements like water...

Minimum Area of Steel for Imposed Deformation Cracking

Minimum reinforcement is provided to ensure that yielding does not occur, and by so doing, cracking is adequately controlled in a...

Deep Learning can be used to Detect Cracks in Fire Damaged Structures

Researchers from Ewha Womans University, Seoul, South Korea, have proposed a machine learning technique for detecting surface cracks on fire damaged concrete....

Important checklists before casting concrete on site

Concreting or casting days are usually big days for site engineers. It is very typical to see engineers and project managers work...

How to price/quote for concrete works

In civil engineering construction works, contractors bidding for a job are always required to specify the rate they will use in executing...

Building collapse – Have you exhausted your factors of safety?

The aftermath of any building collapse is usually horrendous, and the experience is an ugly one for everybody concerned. Human lives might...

Cement Standards and Applications in Nigeria

Cement is one of the most popular construction materials in Nigeria, and has been extensively utilised in civil engineering works such as building construction,...

Procedures in Setting out of Reinforced Concrete Columns

Columns are critical structural elements used in transmitting superstructure load to the substructure. As a result, their stability and structural resistance is...

How to Achieve Grade 25 Concrete on Site

The characteristic compressive strength of concrete to be used in construction is usually specified in the working drawings, design calculation sheets, and...
