The notoriously large carbon footprint of cement production is a prime target for researchers looking to chip away at the problem of climate change, and we’ve seen how this could involve all kinds of tweaks to the recipe. Scientists at Stanford Univers… Continue reading Stanford’s low-carbon cement swaps limestone for volcanic rock
As the mostly widely used material on Earth, concrete has a massive carbon footprint that scientists are working to chip away at in all sorts of ways. Recent research projects have demonstrated how the wonder material graphene could play a role in this… Continue reading World’s first graphene-enhanced concrete slab poured in England
A six-year competition to capture CO2 emissions from operational power plants and convert them into useful products has drawn to a close, and produced dual winners with technologies that promise to reduce the environmental footprint of concrete. The US… Continue reading Fresh recipes for low-carbon concrete take out $20-million XPrize
Concrete is the most commonly used building material in the world, but unfortunately the cement used to make it carries quite a carbon footprint. Now, scientists at the University of Tokyo have created a cement-free alternative that directly bonds sand… Continue reading Cement-free concrete recipe bonds sand using alcohol
Pulp mills generate significant amounts of waste and we’re seeing scientists get quite creative with how it might be put to use, with the possibilities including everything from foams, to batteries to stronger concrete. The latest example comes from re… Continue reading Recycled pulp mill waste adds strength and resilience to cement
Concrete is one of the world’s most commonly used materials, and unfortunately its production is a major source of carbon dioxide in the atmosphere. Now, engineers at Purdue University have developed a new cement recipe that can absorb CO2 twice as fas… Continue reading New concrete recipe improves its carbon capture efficiency
In a list of walls that you’d want to stay strong, those in a nuclear reactor would be near the top. Now, researchers have found that the walls in a decommissioned power plant in Japan have not only kept their strength but have actually gotten stronger… Continue reading Ancient Roman concrete mineral found strengthening nuclear reactor walls
Leaky gas wells are not only a waste of natural resources, but a significant player when it comes to climate change via the release of methane into the atmosphere. Engineers at Penn State University have developed a new type of flexible cement they say… Continue reading Flexible cement is made to fill the fine gaps around leaky gas wells
From the looks of the average driveway or sidewalk, it may seem as though concrete is just destined to crack. But if concrete is so prone to cracking, how are we able to use it in so many high-stress applications like bridges and skyscrapers? This question came about while I …read more
The cement used to construct concrete sewerage systems around the world does a mighty job of helping wash away our waste, but does have its shortcomings. Scientists in Australia have developed a new cement-free solution they say is better equipped to h… Continue reading Cement-free sewerage concrete combats fatbergs and corrosion
