The problem with reinforced concrete. By itself, concrete is a very durable construction material.

The problem with reinforced concrete

The magnificent Pantheon in Rome, the world’s largest unreinforced concrete dome, is in excellent condition after nearly 1,900 years. And yet many concrete structures from last century – bridges, highways and buildings – are crumbling. Many concrete structures built this century will be obsolete before its end. Given the survival of ancient structures, this may seem curious. High hopes for tiny house made from hemp. As any good hippy will tell you, the cannabis plant isn't only good for getting stoned.

High hopes for tiny house made from hemp

Hemp has been used for thousands of years for all kinds of stuff, including making rope, clothing, and even cars. With this in mind, Albany, NY-based Green Built has high hopes it can bring cannabis construction into the US mainstream with its hemp-based tiny house. Joking aside, it's important to note that hemp construction isn't new or even unusual outside the US, and makes sense as a sustainable building material. Green Built aims to use Hempcrete (essentially a mix of hemp, lime and water) to build its tiny house. Seeds planted for London's first wooden skyscraper.

Today's CO2 may become tomorrow's concrete. As carbon emissions continue to rise and cause the planet to warm up, we need to find ways to reduce them.

Today's CO2 may become tomorrow's concrete

Capturing carbon at the source of its emission is one of the solutions, but there is still the problem of storing all the carbon sucked out of the atmosphere. If that captured carbon could be put to good use, then perhaps we could have the perfect capturing system in place. Step-by-Step Earthbag Building.

(materials only) or thereabouts is possible. Other aspects of earthbag building — strength, durability, sustainability, etc. — are all important. A big reason for the growing popularity of earthbag building is its low cost. BioSkin defies urban heat island effect to help keep buildings cool. The BioSkin that coats the NBF Osaki Building in Tokyo integrates evaporative cooling to keep its surface temperature down Image Gallery (9 images) The urban heat island effect, whereby the high concentration of heat-retaining concrete and bitumen causes metropolitan centers to be significantly warmer than the rural areas surrounding them, is a common problem around the world.

BioSkin defies urban heat island effect to help keep buildings cool

The phenomenon is particularly prevalent in Tokyo, Japan, but among the sea of towering structures stands one beacon of hope. The BioSkin that coats the NBF Osaki Building integrates evaporative cooling to keep its surface temperature down and could inspire new solutions to rising city temperatures across the globe. View all The 25-story NBF Osaki Building was completed in March, 2011 and is the first structure to use the BioSkin system. Hardscaping 101: Gabion Walls: Gardenista.

Ancient Roman Concrete Is About to Revolutionize Modern Architecture.

Perhaps this has been known all along – after all, things are no longer built to last (and let’s face it, architecture has generally been getting worse and worse over the years). After 2,000 years, a long-lost secret behind the creation of one of the world’s most durable man-made creations ever—Roman concrete—has finally been discovered by an international team of scientists, and it may have a significant impact on how we build cities of the future. As anyone who’s ever visited Italy knows, the ancient Romans were master engineers. Umbrella facade designed for Shanghai complex.
