Concrete made with Portland cement is the second-most used material in the world by volume, exceeded only by water. Its production process releases massive amounts of carbon dioxide, and so replacing it requires a deeper understanding of its structure at the nanoscale.
This was the purpose of a new study conducted ... |

Engineers at the Massachusetts Institute of Technology (MIT) really outdid themselves this time. They managed to create an advanced three-dimensional printer capable of building numerous structures from scratch, in a fairly limited amount of time.
MIT pioneered the field of 3D printers, which is currently growing... |

Structural engineers may get some new help in their efforts to construct better, larger, more resilient bridges, if they decide to use composite materials rather than iron, steel, concrete and timber. The new materials are a lot lighter, more durable, rust and corrosion resistant and end up costing cheaper than estab... |

There are numerous reasons why engineers and architects would want to employ smart materials in their constructions. For starters, they are more durable, they are especially designed for the task at hand, reduce repair costs, and extend the life of the structures they make up. Some even have self-healing properties, ... |

Concrete is, arguably, the most widespread construction material in the world and, as such, any vulnerabilities it may have are of direct interest to governments anywhere. It makes up most of the current global infrastructure, including most tall buildings, large bridges and roads. Still, after decades in use, the co... |

Concrete pavements can be found anywhere in the world, and they typically cover roads and sidewalks alike. Numerous bridges, buildings, and other similar structures are also made of the stuff, but its toughness and resilience also means that it's impenetrable to anything but a well placed explosive charge. Now, ... |

Oddly enough, many countries around the globe are currently engaged in railroad repair work, attempting to replace millions of miles of tracks that have been left in decay over the years. However, one of the most pressing questions about the repairs, and one that is among the last to intuitively leap to mind, is whe... |

Researchers at the University of Michigan have announced that they have developed a new type of concrete, which is able to heal itself, even when under extreme stress. The team say that the innovative material does not split in large cracks, like average concrete does, but in tiny splinters, which can then fix themse... |

University of Liverpool researchers have successfully tested a new type of concrete that was specifically designed to reduce the damage of bomb explosions. Needless to say, the new material could bring about a new type of security in countries prone to bomb attacks, such as Iraq and Afghanistan, where shaky structure... |

The traditional methods and tools of breaching through walls and other similar tough surfaces, including drills, jackhammers, sledgehammers, saws or explosives can be put aside now, as there's a new speed and safety champion around. The novel device which can be successfully used for enhanced search-and-rescue o... |

According to the Associated Press, the U.S. Nuclear Regulatory Commission (NRC) has recently warned against the oversights that occurred during the process of constructing facilities for the nuclear power generation. The warning has been based on findings, which date from earlier this year and are connected to the co... |

Since there is not water on the Moon and carrying anything there from the Earth would cost loads of money, it is obviously cheaper to use directly the Moon's resources in order to make water-free concrete. US scientists developed a method that would allow for substituting water with the sulfur found in lunar dus... |

Since the dawn of civilization, people have been building tunnels for accessing tombs or underground quarries, or in the hill slopes for allowing the flow of water from porous rocks. Romans were skilled tunnel builders, who made several kilometers long underground passages using the work of slaves. They made a 5.6 km... |

Physicist Phil Metzger warns about the danger of flying rocks that could have energies high enough to smash concrete poles, and punch holes through chain link fences, during the blast off of the solid rocket engines that lift the space shuttles. The exhaust of the engines can blast concrete pieces from the flame tren... |
