Must not know about asphalt yet...

A crumbling asphalt road with a window-sized pothole revealing a layer of red brick underneath

[–] Tar_alcaran@sh.itjust.works 46 points 5 days ago (4 children)

I'm sorry, is this asphalt over baked paving stones? And if so, why?

Or is this a pothole filled up with stone? And if so, why?

[–] insomniac_lemon@lemmy.cafe 39 points 5 days ago (3 children)

It is indeed paved over. I'm sure there are reasons, but probably not good ones given potholes like this. Aside from initial cost, for large vehicles+higher speeds. IMO seems a bit like gluing carpet over wooden floorboards (which is another anger-inducing thing, especially if you've lived in a house with a carpeted bathroom).

Not Just Bikes has a video on brick roads in the Netherlands (the bricks being called Klinkers, video called Natural Handcrafted Artisanal ... Streets?!), how they allow easier maintenance/re-use, brick designs instead of painting the surface after, worn klinkers used in historic areas etc.

[–] Tar_alcaran@sh.itjust.works 24 points 5 days ago* (last edited 5 days ago) (3 children)

Oh yeah, klinkers (if they're baked clay) or the much less inspired sounding betonstraatstenen (concrete street stones) definitely have their benefits, but that video really skips over what a literally backbreaking job it is to pave a street like that, or how slippery these stones get when wet (less so for concrete or textured baked clay).

It's mandatory to do anything over 2 hours of bricklaying by machine now, but that requires packaged stone. And packaging stone is even worse than relaying it from a pile, so you end up loading it into a truck, shipping it off for packaging and then moving it back.

You can design around that, most of the time, but we haven't been doing that, so lots of handwork remains, which is not great for your health.

Of course, running asphalt over a street like this gets you the worst of both worlds, and its begging for potholes since the two materials match up really poorly. You do occasionally see it in the Netherlands on old roads on top of dikes that were "modernized" in the 70s and 80s.

(Edit: it's actually more a synergy of shittyness, because you can't really reuse most of the asphalt, because you don't brickdust in it, and you can't reuse the bricks because there's asphalt on them)

This post kinda feels like op is ridiculing autism with a probably made up story. Hyperfixation is a thing with autists but they don't only talk about one topic and they shut up from time to time too. Autists are more than their hyperfixations, they're humans.

I had a learner on spectrum who physically attacked me for 2 hours because, after our classroom won the 'Golden Trashcan' Award for cleanest room, the Golden Trashcan was not real gold.

The only quote I remember from this was him screaming at me while gesturing at the trashcan, "That's not a thing! That's not even an animal!"

10/10, would teach again.

You didnt have that one kid in any of your classes? A kid I went to school with had similarly deep feelings about evergreens over deciduous trees, and got in a fight with a Canadian kid after he started talking smack about maple syrup and maples in general. I dont think the Canadian wanted to fight, but he had on a Canadian flag shirt so the maple leaf was front and center, making him a target for the arborist. But it was literally trees all the time. Evergreens can photosynthesize year round so they are always giving us oxygen. Evergreen lumber is better for construction. Evergreen seeds are adapted to sprout after fires when there is more likely to be room for them to grow. Nonstop. Middle school is a weird time for a lot of folks and people on the spectrum are not exceptions.

Autist here, while brick houses are nice, I actually own a 100+yo one, they're also not the most ideal material for anything bigger that a midrise.

Wanted to have better insulation for shits and giggles? We have a tool for that: putting proper insulation on the concrete.

[–] frezik@lemmy.blahaj.zone 9 points 4 days ago (1 children)

Some people have some real bad ideas about insulation. No, the air gap in your brick building isn't good. Air gaps are cheap and easy, not good. They do belong in certain strategic locations, but they can't compete with the R-value of filling the space with blown fiberglass. Not even close.

Windows, too. The best, most energy efficient window on the market is at least 3 times worse than a few inches of blown fiberglass. Industry marketing has confused customers on that one.

Don't know why, but I totally get this. Like, 100%, I just have it as a general feeling of disgust that I can ignore.

Edit: specifically cement blocks like the one pictured. That exact shape and texture of cement is the worst for me.

[–] masterspace@lemmy.ca 46 points 5 days ago* (last edited 5 days ago) (5 children)

I understand the distaste for the aesthetics. But it's a pretty inarguably better material from a structural, cost, sound blocking, etc. standpoint.

Don't get me wrong, I love red brick, and personally want a red brick house, but I also recognize the sheer practicality of concrete blocks and would probably pick that with a brick veneer if I actually had to pay for it to be built new.

[–] Jesus_666@lemmy.world 19 points 5 days ago (1 children)

That's literally how many German private houses are built: Autoclaved aerated concrete with a brick cladding. Looks nice and provides a lot of thermal insulation.

honestly I love bricks and hate concrete blocks.

btw what's the most (not necessarily among these two) sustainable building material, lemmings?

[–] Iron_Lynx@lemmy.world 16 points 4 days ago (1 children)

Honestly, whatever makes the most sense with the materials in the local area. And then I don't mean what you can get from the local hardware store, but literally, what the earth in the area provides. If you have lots of clay, then brick would be best. If you have lots of big stones, then stone construction it'll be. If you're deep in the woods, then a wooden building would serve you just right. Maybe a combination of materials and techniques if you have options in the area.

Bonus points if you can build in a way that passively optimises for managing things like moisture and temperature.

[–] hungryphrog@lemmy.blahaj.zone 5 points 4 days ago

Thisss! You don't need to invent some crazy futuristic material when humans have been building sustainably for millenia. All you have to do is look into: 1. what material is avaible in the area? and 2. what enviromental factors do you need to take into account? If you're building in a hot area, the house needs to be able to stay cool. If you're building in a cold area, the house needs to be able to stay warm.

[–] Gork@sopuli.xyz 20 points 5 days ago (4 children)

Stone. It's natural, subject only to the slow erosion of time.

The irony is brick was thought of as cheap when buildings moved to it, from traditional stone blocks. The term "oh, that's so Redbrick", was a slam against something that had become cheap or slummy

I have a similar thing with flat roofs. They are terrible. When you are 5 years old, you already learn to draw houses with a pointy roof. The pointy roof has been invented about a 100 times in history, as people were looking for the best shape. The wave shaped roof tile with 2 waves per tile has been invented about 3 times in history as people were looking for the best shape. The advantages of a pointy roof over a flat roof:

  • Rain flows off. Yes, you can give a flat roof a small inclination, but rain will not flow as well, and if your roof tilts a small bit during the decades, it can become horizontal again.
  • Snow falls off, reducing the chance that the roof collapses under the weight of heavy snow.
  • It is lighter and cheaper, as you can use thinner materials. This is because pointy is a stronger shape than flat.
  • It gives more interior space.
  • It allows more sunlight to reach the street.
  • It has a smaller area-to-vloume-ratio through with heat can escape.
  • Solar panels get a higher efficiency.
  • It allows the roof to be made out of wavy roof tiles which provide the following advantages:
  • Roofs designed with wavy roof tiles can be constructed when it rains.
  • When a tile breaks, you can easily replace it, without having to cut it loose from the tiles next to it.
  • Roof tiles do not fracture upon an uneven heat distribution. Meanwhile, the advantages of flat roofs are:
  • If you design an apartment building, you can copy and paste the interior. (Thus less work for the architect.)
  • A horizontal line is one segment less to draw compared to two diagonals. (Thus less work for the architect.)
  • If a city has the same height restrictions for flat roofed buildings as for pointy roofed buildings, and the architect is too lazy to go to the city council to explain to them that that doesn't make sense, the architect can design a building with more volume by making the roof flat. In other words: the only reason any architect would design a building with a flat roof is because they are either lazy or they have no idea what they are doing.

They better have concrete evidence of these claims tho

Concrete is a major driver of CO2 emissions. Fuck concrete.

[–] RaivoKulli@sopuli.xyz 46 points 5 days ago (10 children)

It's a major driver because of how much it is used. It's the building material, nothing else even really comes close. If we used bricks to the same degree, that would be the major driver.

There's often no good alternative to concrete. There's lots of newer less CO2 intensive cements and cement replacements out there though. Often comes at a cost on something else though.

Did you read that link before posting?

In comparison with other construction materials (aluminium, steel, even brick), concrete is one of the least energy-intensive building materials.[2]

Okay I am a big fan of brutalist architecture. Guess I am in the minority... I feel the philosophy behind it is just being wildly misunderstood.

[–] unconsequential@slrpnk.net 21 points 5 days ago (6 children)

Modern and brutalist architecture can have that effect on people. Fuck concrete, and fuck neo-imperialist colonial architecture.

Concrete is horrible for the environment and its fucked up global emissions of buildings and architecture. (Cement production alone constitutes 8% of global emissions, not considering its inefficiency in thermal lifecycles of a building and ultimate un-renewable waste). It is in fact not the best fit for every circumstance.

One shoe fits all architecture trends have effectively killed vernacular wisdom and climate conscious local innovation. Favoring “cheap” garbage that jacks up costs in other sectors, damages climate and ignores localized need, requiring complex, often power-hungry, solutions like extensive BAS to try and counterbalance their piss poor application.

(For those unaware modern buildings when all is said and done account for over 40% of global emissions. And the heating/cooling systems far outpace keeping the lights on in terms of energy consumption (something like 2/3 of the total buildings demands over time). Tackling that behemoth number is going to take a multifaceted approach but the importance of materials and place-specific design cannot be understated.)
