Re: The hearth questions and progress pictures Hey George. My oven is still in progress (slow at the moment, I have company and it's been insanely hot here), so I can't tell you how wonderfully it works, but I have 4 inches of vermicrete on top of my structural layer (I used cove base as the form, worked pretty well) and 2 inches of insblock19 on top of that.
Nov 08, 2013· Lowdensity aggregates, such as perlite (274) and vermiculite (275), are important ingredients in modern plasters. Reducing the density of plaster products has a number of advantages including lower transport costs, less effort to mix/apply, it can be used in thicker layers (without sagging), and it has improved thermal insulation and fire resistance properties.
Perlite concrete mixed at a ratio of 1 part cement to 6 parts perlite has an insulation value, or "k" value, of and a compressive strength of 125 to 200 pounds per square inch. At a ratio of 1 part cement to 4 parts perlite, you achieve a "k" value of and compressive strength of 350 to 500 pounds per inch.

The use of this information is for perlite concrete applicators responsible for the installation and application of perlite insulating concrete. – Definition Perlite insulating concrete is a combination of perlite aggregate, Portland cement, air …
Cementitious materials and concrete have been used since thousands of years by mankind. The oldest archaeological finds of concrete date back to about 5,600 [Bhatty 2004]. Today, Portland cement based concrete is the most used solid materials .In 2014, it has been estimated that Gt cement were produced worldwide [USGS 2015].

I need a refractory for my 2 bucks inspired furnace, and I need to be able to get the materials from a home improvement store. I looked at lows online and they have a 3000 degree furnace cement, it is called Durst DoAll Furnace Cement, and it is 1/2 gallon pre mixed in a tub. I also saw some type of fire clay that is really cheap, 8 for 55 lbs.

I'm trying to find the specific gravity (Relative density) of a few lightweight aggregates to be used in a concrete canoe. Normally this wouldn't be an issue but due to the aggregates being quite light (estimating a SG of .5) we're unable to test for the specific gravity as they float on top of the water and thus don't mix with it.
