How to Prevent Cracks in Concrete? Causes & Repairs of Cracks in Concrete (Part 2)

(2) Proper Concrete Mix Design and use of Quality Materials

The concrete itself must be properly proportioned, and properly mixed.  If you use too little cement, you can almost guarantee cracks.  Using too much water

Engineers Who Changed the World in the Past 200 Years

There are thinkers and there are doers. Engineers are both since they possess the skills, knowledge and innovative capabilities to change world views. The following are some engineering greats who have facilitated mankind with inventions that speak for themselves:


Alessandro Giuseppe Antonio Anastasio Gerolamo Umberto Volta

Yes his name can be a mouthful but that can be forgiven if we take his invention into account: the battery..

DISCUSS: How can Engineering Help Developing Nations Solve Critical Problems?


I was recently listening to Dr. Tony Marjoram, the former head of engineering sciences at UNESCO on  his discussion on how engineering can help developing nations solve critical problems.   It was a quite stimulating discussion in which Dr. Marjoram provides the following blueprint answering the subject question:
He acknowledges that engineering is vital in ensuring human social-economic development.  The role that engineers continue to play in solving development issues (transporation, housing) cannot be underestimated. However, he concurs that there is an increased shortage of engineers around the world.  This reality is compounded by the fact that the profession is not attracting as many students, especially in light of the numbers needed to allow us to meet the social-economic obligations around the world.
Obviously the profession should increase its public awareness efforts and rebrand itself as the profession that promotes humanitarian development.  Unfortunately, given the fact that we still lack safe water, sanitation and electricity around the work; Perhaps we as engineering professionals are not doing enough to deliver solutions to problems we are mandated to solve.
In your opinion, how can engineering be adequately applied to be more effective in delivering solutions for these problems?

Raft Foundation Construction Tutorial


Raft foundation

In case of soils having low bearing capacity, heavy structural loads are often supported by offering raft foundations. Additionally if the structure is susceptible to subsidence on  being situated in mining area or because of unsure behavior of its sub-soil water condition,

The Engineering Challenges in The 21st Century

Technology has dramatically shifted the landscape of today, driving up innovations and enhanced functionalities into the modern world. Opportunities are fast arising as new developments spurt in almost every field, and with it, a growing demand on engineers who are faced with the challenges to broaden their skills and master various technological disciplines. Below are some of the forces driving and shaping the engineering world:

1. GLOBAL SUSTAINABILITY

A growing population and invasive activities on the global environment has raised the question on whether mankind can live in a sustainable manner and for what period of time.
Engineers are constantly faced with the challenge

China's first suspension railway completes test run

Photo taken on Sept 30, 2016 shows a lithium-battery powered train suspended from a railway line in Chengdu, southwest China's Sichuan Province. China's first suspension railway line finished its test run Friday. The train, which has a speed of 60 km per hour, successfully ran along the 300-meter test section of the railway line after being suspended from the line.
