Cement: The Latest Architecture and News

As you read this, you may notice that you are surrounded by several items made of plastic. This omnipresence is no coincidence; the versatility of plastic has made it suitable for a variety of applications, and was described by its inventor—Leo Baekeland— as “the material of a thousand uses.” However, when it comes to environmental impact, the problem lies in its very qualities: it is so durable, adaptable, and easy to produce (430 million tons per year) that, according to UN data, the equivalent of 2,000 garbage trucks full of plastic are dumped into the oceans, rivers, and lakes every day.

In the built environment, plastic has been incorporated into various materials, products, and construction systems, contributing to an environmental crisis that seriously affects the well-being of millions of living beings. Faced with this problem, one possible direction is to shift away from utilizing it. The search for plastic-free alternatives is marking a path toward a future where architecture is progressively disassociating itself from these polluting materials, promoting sustainable solutions that reduce our dependence on it and contribute to preserving the environment.

MAD Architects has unveiled the project for the renovation of the "Wanmicang" warehouse on the southside of the Shanghai Zhangjiang Cement Factory. The building is set to be transformed into a multifunctional public waterfront space for culture, creativity, and commerce. The project maintains the character of the former industrial site but introduces a new addition in the form of an ark-like metal 'floating' volume, creating a stark contrast between the old and new structures. The project is scheduled for completion by 2026.

ArchDaily and VELUX have joined forces to provide you with an exclusive coverage of the highly anticipated UIA World Congress of Architects 2023. Watch Sebastian Peck from KOMPAS VC and Liz Gilligan from Material Evolution explain a revolutionary low-carbon cement produced from industrial waste, and how can it help to decarbonize architecture by reducing a building's carbon footprint by 85%.

It is expected that by 2050, the rapid depletion of raw materials will leave the world without enough sand and steel to build concrete. On the other hand, the cost of building continues to soar, with an increase between 5% and 11% from last year. And with respect to its impact on the environment, the construction industry still accounts for 23% of air pollution, 50% of the climatic change, 40% of drinking water pollution, and 50% of landfill wastes. Evidently, the construction industry, the environment, and the human race are facing several challenges that are influenced by one another, but it is the human being who is at the greatest disadvantage.

As a response to global challenges such as climate change, discrimination, and physical vulnerability, designers and engineers from across the world have developed innovative construction materials that put the human wellbeing first in urban, architecture, and interior projects.

Concrete and sustainability are two words that are often considered incompatible. Used as early as the Roman era, concrete has shaped much of our built environment, being the most widely used manufactured material in the planet thanks to its resistance, versatility, cost-effectiveness, and accessibility, among other inherent benefits. Its popular use in buildings and infrastructure forms the foundations of cities, connects communities, and will continue to play a vital role in providing solutions to the challenges of the future – especially as cities must respond to a growing global population. But with cement as its key ingredient, it also comes with several environmental costs, being responsible for at least 8% of the world’s carbon emissions in a climate-change context. However, it doesn’t necessarily have to be that way. With the rise of innovative technologies and products, there are many ways to make concrete greener.

The new headquarters of the building materials manufacturer HeidelbergCement consists of three interconnected building sections of different heights. The atrium of each building section provides plenty of light and luminance. The building was opened in June 2020 and provides up to 1,000 employees with a state-of-the-art work environment. The architectural firm AS+P Albert Speer + Partner based in Frankfurt was responsible for the project as a general planner, and carried out the design in collaboration with W+Architektur, with the latter providing the consulting office for the client’s project manager.

PERI, one of the leading formwork and scaffolding manufacturers worldwide - and the building materials manufacturer HeidelbergCement - combined their architectural and concrete expertise for the execution of this project. In doing so, the existing limits of PERI’s concrete construction offerings were pushed. The architectural highlights of the project were successfully realized using special PERI formwork elements.

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.
