The lime that concrete is made of is alkaline, so if you’re very careful a little bit may simply neutralise the acid. Neutralised… I think it’s just chalk? Don’t do this though, it wouldn’t take much to mess it up and do serious damage to your insides. Plus idk if it’s actually just chalk. Also if you wash your hands with vinegar after a day working with cement it gets rid of the horrible dried out feeling and feels nice & creamy, because it neutralises the base.
This is funny because when I was a plumber after particularly dirty days I used to wash my hands with cement and I used to think that made my hands feel smooth
At the same time, we generate about 10 billion kilograms of used coffee grounds over the same span — coffee grounds which a team of researchers from RMIT University in Australia have discovered can be used as a silica substitute in the concrete production process that, in the proper proportions, yields a significantly stronger chemical bond than sand alone.
“The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change,” lead author of the study, Dr Rajeev Roychand of RMIT’s School of Engineering, said in a recent release.
He notes that Australia alone produces 75 million kilograms of used coffee grounds each year, most of which ends up in landfills.
In order to make the grounds more compatible, the team experimented with pyrolyzing the materials at 350 and 500 degrees C, then substituting them in for sand in 5, 10, 15 and 20 percentages (by volume) for standard concrete mixtures.
“The concrete industry has the potential to contribute significantly to increasing the recycling of organic waste such as used coffee,” added study co-author Dr Shannon Kilmartin-Lynch, a Vice-Chancellor’s Indigenous Postdoctoral Research Fellow at RMIT.
"Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill,” where its decomposition would generate large amounts of methane, a greenhouse gas 21 times more potent than carbon dioxide.

Looks great, but I’m skeptical if it’ll ever see an actual release. Remastering the entire game with the kind of asset quality we see for this single room would require an enormous amount of time and effort, especially with people working for free.
the modders are also using an early version of RTX Remix to add extra model detail (through Valve’s Hammer editor) and rework materials with physical-based rendering properties.
From what I’ve seen the RTX Remix tool has some AI for texture upscaling and assigning materials but a lot of stuff (like making higher resolution models) still has to be done by hand.
You’d be shocked at the work modders are willing to put in for free when working on a game that they love - and Half Life is a series that a lot of people absolutely adore!
That’s true, but it would also be far from the first time for a mod to go nowhere due to people biting off more than they can chew. I’d be happy to be proven wrong though.
I tried the demo, but it suffers from the same issue that tight urban 3rd person view games have: A camera that jumps a lot when swinging it around due to obstacles and walls.
In nearly 17 years at Valve, Wood helped build and ship the company’s most notable titles, including Left 4 Dead, Left 4 Dead 2, Portal 2, CS:GO and both episodes of Half-Life 2. He was a founding member of the CS:GO project and worked on that series for six years; he was pivotal in crafting Portal 2’s co-op mode, and he created choreography and combat scenes in Half-Life and Left 4 Dead. Level design was one of his specialties.
You have my attention.
“It really is more about cozy exploration,” Wood told Engadget. “The game has aspects of platforming, but it’s very light platforming. It’s more about exploring vertically, and exploring nooks and crannies. I’ve done a lot of things throughout my career, but one of the things I spent a lot of time doing was level design in video games, so I have a lot of personal interest in creating spaces that feel fun to explore, to sort of poke around in.”
