Concrete Garden Bench

Rated 2 out of 5 by Bobb from Nice Product But? This kit makes a nice bench for the yard or patio. Pavestone makes a quality product. However this kit does not come with a wood bench. You must purchase the bench materials separately and build it at an extra cost. The bench kit comes only with pave stones to make the stands to support the bench. For the price without a bench its not a good value. I purchased the materials to make the bench i.e. the pave stone, lumber, nails and wood stain for much less than the price of the kit at my HD. So if you want a bench, purchase the materials at HD separately and save some money. Date published: 2016-05-18

Thanks for the advice!

I did calculate the amount of rebar that's necessary. It's not a hard calculation, I calculated it with a 300kg force in the middle of the bench. At architectural engineering we always use big safety margins;). The outcome is you need 0,05% of steel in the section cut of the bench. This leads to a steel surface of 30mm2. A piece of 6mm rebar has a surface of 28mm2. So there isn't a lot of rebar necessary. I can tell you a lot more about this kind of calculations, but for this particular bench it isn't really that important. When you make the seat thinner though the needed amount of rebar increases rapidly!

I waited longer to demold the bench because i have to flip it upside. When the concrete cures for 2 days it's strong enough to demold. But when you flip the bench upside the corners of the legs will definitely be damaged and chip off.That's why i waited a little bit longer.

You can easily make lighter variations by the addition of other substances to normal concrete without particularly compromising the strength of it (like anything, there are always trade offs).

My brother experimented extensively with alternative forms of concrete for another project he was doing. I can ask him about it and post back here if you'd like.

At the risk of increasing the mold complexity, the obvious solution to the problem of weight is to cast voids into the legs and underside of the bench. Yes, there would be a reduction of strength, but not significantly so. Were it me, I'd probably have tried to incorporate polystyrene into the center of the pour so that none of it was visible but there would be less weight.

The whole weight/construction issue seems to me to be essentially about the weight bearing capacity of the bench. Ignoring the parts of the bench over the legs (because they'd be the strongest) you'd really need to identify the max load capabilities of the unsupported center section to really get an idea of what you can and can't do with materials.

I used 10 premixed concrete bags (25kg each). The premixed bags are easy to use. When you want to make your own concrete you have to put the cement, sand and gravel together. 1 part cement, 2 parts sand and 3 parts gravel. When you change the size of the bench you have to calculate the amount of concrete you need. A 25kg bag of concrete is good for 12 liters.

In order to counter the reduction in strength, two pieces of rebar cut and bent to run the verticals (legs) and horizontal (seat) as one solid run of 1/2" to 3/4", embedded into both sides of the bench would be enough.

Then, the pieces of polystyrene (lightest alternative) or even fiberglass batting could then be placed as filler and embedded with the rebar. However, and this is the trickiest part, the rebar will need to internally connected with enough concrete that is structurally solid with the non-filler based concrete to give strength throughout the total structure.

Now, this is just my thought on how to approach reducing the weight while maintain strength. I will appreciate any feedback or suggestions. Who knows, I might even try to build one that way. Thanks.

Yes, that could be a problem, especially in a warm, humid climate like here in Florida. Do you suppose a final top surface could be embedded into the mold that would cleat to the papercrete mixture? Perhaps an initial spread of the original mixture–say, 1"-2" –laid into the bottom of the mold first (top surface of bench) and allowed to firm up slightly. A concrete sealer is a possible solution to help avoid water soaking into the paper fibers. Either that or some well-placed coatings of polyurethane or lacquer paint.

BTW, what do you think about the papercrete and modifications that we discussed earlier using the pvc tubing /rebar? Much lighter, yes. But where do you think it would stand on strength at that point?

I like the project, the bench, and its usefulness. No one will ever steal it from the owners by simply picking it up and running off with it! 😉

What I would be interested in finding out about is whether there is a suitable filler material that could be used to reduce the weight while maintaining adequate strength. I've heard of bamboo fibers being used for some projects, while fiberglass can also be used.

If so, does anyone have an idea regarding the ratios that could be incorporated to displace some of the concrete while still producing a strong product?

To sand on concrete we use a very hard bar called a Truing stone, sold in hardware stores. I agree, don't like to uncover the rock, but in a couple of years, rain will remove the top layer of cement and you'll see pebbles anyway. So maybe first concrete into the mold (becomes the TOP surface) could be Sand Mix, no pebbles.
