Examine latest technic trends by industry peers
Examine latest technic trends by industry peers
In 2012, AGG1 and World of Asphalt will again be the place to network with industry peers and examine the latest technologies and emerging trends. Some 93 percent of attendees at the last event said the shows were valuable to their cone crusher businesses and 97 percent said they were satisfied or very satisfied with the shows.
NSSGA Annual Convention will also be held at the Westin Charlotte
hotel adjacent to the Convention Center. This close proximity allows for all
convention attendees to easily attend AGG1 and the World of Asphalt. Internal
combustion engines have been around for some 150 years. They are undoubtedly one
of the most significant inventions in human history, but they are not without
their problems. The metal-on-metal movement means they need constant
lubrication, they have lots of moving parts, get very hot, are heavy, fuel is
getting more scarce and more expensive, and new laws to cut harmful exhaust
emissions mean a lot of expensive technology needs to be used to reduce
pollutants.
“Heating with concrete, cooling with clay” – the provocative
title of the second discussion round with German winners of the Holcim Awards
again attracted more people than the lecture theatre could accommodate at the
Aedes Architekturforum in Berlin. Some 130 people including a group of guests
from Holcim Southern Germany showed interest in learning more about the “Smart
Material House” in Hamburg and an educational center for sustainability in
Marrakesh, Morocco. But for all their drawbacks, they are wildly successful.
There are billions of engines in use around the world today in cars, trains and
ships, as well as in industrial applications and off-road equipment like
construction machines. Diesel engines remain the overwhelmingly popular choice
to power equipment in this industry.
Following presentations by the design
teams, architecture critic Andreas Ruby moderated a podium discussion seeking
answers to the question on how building materials can be used to the best –
taking geographic, climatic and above all sustainability factors into
consideration.
As Gwenne Henricks, president of Perkins explains in this
month's interview, that is because diesel engines have a lot going for them.
They are power-dense, meaning you get a lot of energy out of a small package,
the fuel is easily portable, and a reasonably manageable quantity will keep an
engine running for a long time.
Whereas architects Frank Barkow and Regine
Leibinger together with engineers Mike Schlaich and Matthias Schuler designed a
multistory “card house” for IBA Hamburg using precast concrete wall elements and
wooden floors, architects Anna Heringer and Salima Naji together with materials
specialists Martin Rauch and Elmar Nägele re-invent traditional building
techniques and show in their large-scale educational center the potential
offered by combining modern ball mill technology with
low-tech building material such as natural clay.
