Re: [papercreters] Re: Ron & Doris Papercrete Formula/ database



Got into the entry screen. What we need is a list of standard material to pick from and indicate quantities so that it can be cross referenced and searched by material.

The only accurate way to measure the ingredients is by weight (yes water comes in gallons, but each gallon weighs a specific amount). Dry paper gets a lot heavier when you add water to it. When draining, the water loss varies depending on what you are draining on, humidity, wind, temperature, etc. To say dump it on the ground and then use it the next morning, there is no way you can be accurate. That's OK as a general guideline and sure, it works, but for any kind of code acceptance you have to have accurate measurements. A certified testing lab won't accept gallons of semi wet pulp as a quantity.

There's nothing wrong with doing it the way Ron & Doris, and Judith, are doing it. That works great for a one-off project. If we want standard formulas to yield consistent results then we will have to use standard measurements and standard tests.

Another point not related to the database, trying to mix papercrete like the concrete guys do it just won't work. Most people with concrete backgrounds choke on the amount of water used in mixing and say it'll never work. Fact is that most of the water drains away leaving the cement in place. If your papercrete gets hard enough to knock on after just a couple of hours, you are using way too much cement. Papercrete isn't concrete and goes through a completely different curing process.
