Re: first time foaming basement cement


There is a pretty good article on foamcrete in Wikipedia, see https://en.wikipedia.org/wiki/Foam_concrete.

This is a real product with a variety of applications, however house construction is not a typical use for foamcrete.

The most common method is to use lighter weight aggregates - manufactured expanded aggregates or natural light aggregates (scoria, pumice).

I was involved in the manufacture of conventional shape concrete block made from expanded polystyrene beads mixed with manufactured and/or normal aggregates. In order for it to work, the heavier aggregate must be finer than normal to be mixed uniformly and a wetting chemical (wetting agent) must be used to permit the cement matrix to bond to the lightweight expanded foam beads. We were able to make loadbearing 8" block in a block plant that weighed less than 18#(they went into my lake home) that the masons loved. There is no way a contractor can get the control and uniformity of real lightweight construction on a job site.

The "crumbled"/shredded waste foam boards with variable properties are good for nothing except poor construction with no controls.

Your post makes sense to me, i doubt any concrete producer in the USA would be involved with something like that, as it would involve dedicating a plant to the sole production of that item, and that i doubt would happen.

I'll bet your masons were happy, with the light weight blocks being 18 lbs. as opposed to the standard 28 lbs.

Re: first time foaming basement cement


I am familiar with the performance or as some people say "insulation value". Many people in the U.S. are not aware of the benefits of "thermal inertia" that is a real proven money saver. Unfortunately, it is easier for domestic product/material suppliers to market the fallacious "R-value" that can be totally misleading.

If you ever sit on a code or standards that tries to write an enforceable code or materials standard it is like facing the opponent with an unlimited checkbook and an unlimited number of employees.

And i doubt you will see it in the foreseeable future, of all the schools and seminars i've attended over the years, it was never even mentioned, you would also have to dedicate a central mix plant to avoid contamination with standard concrete, that alone would send the cost sky high.
