Breaking the bond between the concrete and the steel reinforcement bars is now less noisy and messy

Published in Other News

MIT students have found a way to produce plastic-reinforced concrete that is up to 15% stronger than conventional concrete, by adding irradiated bits of plastic water bottles

A rectangular column (400mmX400mm) is constructed of concrete and four steel reinforcing rebars. An axial force of 1000KN is subjected on the column. What is the diameter of the steel bars if the ¼ of the load is transferred to the steel bars and ¾ is transferred to the concrete? ( EST=200GPa, Ec=25GPa)

The company claims that about half the time or less is needed to erect a residential structure compared to the time it takes to build using the traditional methods

They used the principle of plant photosynthesis to create energy

It is a common phenomenon for the traditional concrete to crack, requiring maintenance and reparations before reinforcement starts to corrode. Luckily, it seems that Delft University microbiology professor Henk Jonkers has found the solution to this problem. Inspired by nature, he developed ‘Bio-concrete’, a new type of material that brings together biology and civil engineering and could save billions in construction costs by improving the lifespan of buildings, bridges and roads. "It is combining nature with construction materials. Nature is supplying us a lot of functionality for free - in this case, limestone-producing bacteria’’, says the professor.

Video: 'Thirsty' Concrete Absorbs Water!

The cement Topmix is designed to have a super-absorbent masking surface that allows water to seep through it instead of sitting, in an effort to combat flood.

57-Story Skyscraper Built in 19 days!

Broad Sustainable Building, a construction company in China, recently built a 57-floor, 2-million-square-foot skyscraper in just 19 days. That is an average of three floors per day. The building has 19 10-meter-tall atriums, enough office space for 4000 people and 800 apartments. The structure is made up of prefabricated sections that reduced the use of concrete by 15,000 trucks, which translates into less dust released into the air.

Fibers to help fire damage prevention in tunnels

Engineers at the Technical University of Munich (TUM) have come up with a way to prevent concrete spalling caused by excessive temperature built up during a tunnel fire. The new technology consists of fibers added in the concrete but the changes in concrete behavior remain still to be investigated.

The city of Santa Monica, California will spend $100,000 over the next year identifying steel, concrete, and wood-frame buildings that would be vulnerable to an earthquake. If investigators determine that a building is at risk, the owners of the building must retrofit the structure to comply with current building codes. A timeframe for when building owners must complete the retrofits has not been announced.
