Re: [papercreters] Re: Cement & Concrete FAQs (Frequently Asked Questions) Portland Cement Association (PCA)

Another question... You said the papercrete "squished apart" at 1600 psi while a compressed block "let go" at 1630 psi. I'm assuming that by "squish," the papercrete failed plastically while the compressed block failed instantaneously/catastrophically. Could we have some details about the compressed block?  What was the compression method during its formation?  Its constitute material? That sort of information. If the papercrete failed plastically, was it not fully cured/set prior to being subjected to the compressive test? Inquiring minds want to know.

What did the papercrete look like when being squished at 1200 PSI? I guess I'm asking how much it flattened before it broke up. Do you remember what the formula was for this papercrete?
