When we think of concrete, the color gray generally comes to mind. The traditional mixture of concrete, which comprises cement, gravel, sand, and water may vary in color depending on elements and admixtures but naturally varies from light to dark gray. However, compounds that add pigment to the mixture are becoming increasingly prevalent and popular, as they infuse the concrete with hues more stable than paint. These shades result from the addition of oxides: yellow, red and their derivations (eg. brown) are obtained with the addition of iron oxide; chromium and cobalt oxide create the greens and blues, respectively. For black concrete, it is common to use black iron oxide and carbon oxide combined with pozzolanic cement.
The idea of turning cold, raw materials into elegant shapes has always fascinated artists, architects, and designers. In the Carrara marble sculptures of Lorenzo Berdini and Michelangelo, human forms were carved from heavy blocks of stones with great detail and precision. There is no difference in architecture: from taking a light volume off the floor, to leaving a small indentation between a structure and a fence, to altering the lining of a block, there are several devices to make buildings visually lighter.
Online courses have gained more and more recognition in the past couple of years. In addition to the flexibility and convenience of learning wherever and whenever you want, they provide access to content from well-respected professors and colleges. In the field of architecture and construction, online courses have grown exponentially. Last year, we compiled a list that focused mainly on constructive and material techniques. This time we selected 15 online courses covering a range of subjects. We hope this selection of courses can help you with your next project.
3D printing itself is no longer a new technology, but that hasn’t stopped researchers and innovators around the world from coming up with new applications and opportunities. Some experiments with new materials have been driven by sustainability concerns and others are simply the result of imagination and creativity. Others have chosen to invest their time utilizing more traditional materials in new ways. Materials, however, are just the beginning. Researchers have developed new processes that allow the creation of objects that were previously impossible to print and, on a larger scale, new building typologies are being tested - including a Mars habitat!
For thousands of years, concrete has been a foundation of the built environment: the most widely used man-made material on the planet. However, as architects, and the public alike, sharpen their focus on the causes and effects of climate change, the environmental damage caused by cement has become a subject of unease.
As exhibited in a recent in-depth article by Lucy Rodgers for BBC News, cement is the source of about 8% of global CO2 emissions. The piece was written off the back of the UN’s COP24 climate change conference in Poland and found that in order to meet the requirements of the 2015 Paris Climate Agreement, annual cement emissions must fall by 16% by 2030.

With the exhibition soon coming to an end, Martino Stierli (Chief Curator of Architecture and Design at MoMA) and Vladimir Kulic (Guest Curator and Architecture Historian) have presented a 7-minute-long video guiding viewers through the highlights of the exhibition.

A series of concave concrete panels hoisted on slender plank-like columns sit amongst the vast rural plains of Sweden, silently redefining the typology of an otherwise utilitarian structure. White Arkitekter's recent proposal for a water tower in Varberg is a slim horizontal structure, deviating from the typical, vertical and round design. Titled VÅGA, it features two tanks for storing water within its unique shape that may actually be better suited to its purpose.
The architectural and engineering feats of Spanish architect Santiago Calatrava can be admired around the world, but his City of Arts and Sciences, designed alongside Felix Candela, has remained a modern architectural marvel. Like many international visitors, Lebanese photographer Anthony Saroufim found himself inherently attracted to the highly publicized building complex with a specific, tailored angle - unraveling the relationship between the built reality and the people interacting with it.
Alvaro Siza orchestrates, like no other, the experience of the visitor in his works. By means of compressions and decompression, openings and closings, volumes, voids and light, the Portuguese architect marks the paths, points of view, and perspective of the passage of time. In this photo essay, Ronaldo Azambuja photographed the Iberê Camargo Foundation ten years after its inauguration.
