Also, you cannot expect the lightweight concrete to puddle into a completely level surface with some troweling and checking with a level. A 1:6 (one part Portland cement by volume to 6 parts perlite by volume) mix would be appropriate and add enough water to make it easily spreadable, but not so wet that it is dripping.Web

The more cement you add to a papercrete mix, the less shrinkage and settling, going as low as 3 to 5%. If you want to make papercrete mortar or plaster, mix paper pulp with cement in a 50/50 proportion.

To make an 18 x 12 x 9-in. planter, you need approximately 2 gallons of sifted peat, 2 gallons of perlite, 1-1/3 gallons of Portland cement (about 12 lb.), 1 cup of loosely packed reinforcing fibers, and water. To test for the right consistency, squeeze a handful of mix. You should be able to get only a couple of drops out.Web

Perlite is what gives your concrete that porous texture when finished. Add one 5 gallon bucket of perlite to your mix first. Perlite will absorb the water in the mixture and thicken your mix. Depending on how thick you want your mixture, add anywhere from 5 to 25 gallons of perlite.Web

Vermiculite Concrete Introduction Vermiculite concrete is a low density non-structural construction product. It is insulating (both thermally and acoustically) and intrinsically fire resistant. It is normally made simply by mixing exfoliated vermiculite as the aggregate, with cement and water, plus additives such as plasticisers if required.Web

For a 4:1 (aka 80% perlite) mix, you fill up any random container 4 times, dump it in your mixing tub/bucket, then add 1 scoop of the cement.

Perlite is a volcanic mineral with a high R value, which means it does not conduct heat well; it is soft compared to load-bearing aggregates. Mixing perlite with concrete is a matter of proper portion; you must mix the correct ratio of perlite, cement and water. The more perlite in the mix, the higher the R value, but the lower the structural ...Web

The flow curves of concrete mixtures without perlite and with 3.75% (volume) perlite addition versus the amount of cement after mixing and 60 min show that both when increasing the shear rate and decreasing it almost coincide, i.e. the mixtures are not thixotropic and their viscosity depends little on the shear rate.Web

This paper presents the test results of the lightweight concrete properties obtained by adding expanded perlite (EP) to an RPC mix in quantities from 30% to 60% by volume of the concrete mix. It has been shown that in these cases it is possible to obtain concrete containing 30% by volume with density of approximately 1900 kg/m3 and the …Web
