Custom concrete is typically used, silica fume and glass fiber with high air entrainment. Also use glass microspheres instead of sand. Concrete with a density of 800 kg/m³ can be made, this floats in water.

She started life as a Catamaran Sailboat, and I strip it of everything pertaining to the sailboat. She had 2 4cyl Mercury inboard stern drives. By the time I was finished I had a Speed Demon, on plane on open ocean, I reached 75 mph top speed

@martin_mue Жыл бұрын

For concrete to cure to its maximal strength you need to make sure that the concrete stays wet for a few days. That is especially an issue with such thin parts as they dry out quickly. The reason is that the chemical reaction (hydration) needs water to work. If the concrete dries out, calcification starts and that creates just weak chalk.

Yes the longer it cures the stronger it gets but if they used a plasticizer and a fiber glass filler which speeds up the curing process with the addition of additional strength then there shouldn’t be an issue with it cracking. Also the way they got it out of the mold was awful. It would be better to drill a hole in the mold and shoot compressed air into it to have it release

That’s not quite the story, there were two harbors made, A and B for American and British. Those harbors utilized caissons called “Phoenixes” which were giant concrete tubs, pump out the water and they float, fill with water and you have a breakwater or mole for offloading ships. Some of these caissons are still around today as they’re quite robust but they were designed to be easy to sink in place.

Some cement used for tile work is formulated to be somewhat flexible. If whipped up with air bubbles it might not be as strong but it will be lighter. It's still a Portland cement based product so flexible and light is relative... You should also try plaster. At least bring some of that plaster like you make a cast out of , for an emergency patch , if you spring a leak , if you do a full size boat, plaster can set underwater

They also add fiberglass fibers to the cement to make it a lot stronger. Once it's out of the mold, they polish the cement to a shine and wax the heck out of it. They also make toboggans in a similar way.

Fun Fact: During WW2, German engineers were tasked with finding a way to patrol and protect waterways and river ports from Allied attacks. One way in which this was done was to take a concrete barge pontoon, add a wooden deck, engines, and a control hut. Then, on each corner, quad 20mm anti-aircraft turrets were placed, and supplied with a mixture of explosive and armor piercing ammunition. This proved a very slow but fairly menacing craft.

I work making concrete sculptures using fiberglass molds and there are a couple things special about the concrete mixtures we use as well as how me pour them. First off as the mixture goes. It is important to use some sort of Plasticizer in combination to gain strength and flexibility in the concrete. Second the concrete should be thicker in a uniform sense….so a two part mold would be a better idea. If it is a quarter-half in thick all the way around you will certainly have less issues with it shattering.

Instead of mesh try chopped fiberglass. Typically it's just bits of around 10mm long fiberglass strands. They get mixed into the concrete for pours that need to be incredibly strong, sometimes as a complete replacement for rebar. Saves time/$ on building rebar cages, and in some ways it is even stronger since the strands are mixed in uniformly instead of being basically one layer. Plus nothing for rust to attack! Not sure what mix you used here (looks like gray Portland cement + sand, maybe a 2:1 ratio?), but there are much stronger mixes out there. Something like 1:1:2:1 of _Gray Portland Cement + White Portland Cement + sand + Fiberglass_ should give much better results. Do give your local concrete mixing plant a call before building the full-scale boat though, they would be able to help you way more as far as mixes/additives go. There are many recipes out there and the most common one is only 3000 PSI (takes 3000 lbs to crush a 1x1x1" cube), but they go to 6000 and maybe even higher. And lastly, let the thing set for a while. Technically concrete is strongest after about a month, but it should not even be de-moulded sooner than about 2 days for something this thin.

@VigilanceTech Жыл бұрын

Benford did extensive testing on ferro-cement panels made of different thickness/compositions. One I recall, was a 4'x1'x1/2" plank propped up within 1 inch of it's ends where a sharp woodsplitter type blade was pressed down in it's middle. It ended up bending over 4" with over 700lbs applied to the blade before it broke leading to a PSI rating of 19,500 LBS, e.g. sufficient to sink into the the bottom of the Marianas Trench without imploding.

Hi peter ..I've had some experience in building concrete models ..I studied architectural design under a ship's architect named Richard serving ..about 50 years ago.... for the purpose of model building we used plaster cast material.. like the doctors used to use for broken arms ..this way we kept the weight down and could control the thickness of the hull .. it was already reinforced with a cotton cheese cloth .. then to seal it we used fiberglass resin ..of course nowadays I'd probably use a really good epoxy.. believe it or not .. this type of hull worked extremely well and was very forgiving ,sandable and fairly lightweight.. I also learned plank & frame building at the time .. I think I was around 6 or 7 wen I took those classes and have enjoyed model boating and rc ever since .. I hope that tid bit helps ..I think you'd be surprised.. another not to well known material that was nearly used to build an aircraft carrier was a mixture of water and sawdust that was frozen into a solid ..that was called piecrete.. that stuff is amazing..it held up extremely well to all kinds of artillery and gunfire .. and of course it didn't sink ..being ice ..look it up ..just for kicks

FYI the mesh will definitely still give the boat support, but it's not really doing the same thing as rebar. At least not how I understand it's use in things like bridges. The rebar is stretched, the concrete poured and cured, and then the tension released. Concrete is incredibly strong in compression, but very weak in tension. So by doing this the rebar is constantly keeping the concrete in compression, even on the underside of an arched bridge that is flexing from the weight of cars passing over.
