That's quite a resumé!!
Re: [YucaLandia] Percentage of Cal is Best for a Strong Concrete Mix for Cantara Stone Wall and O

But with such a wealth of knowledge to draw from forgive my surprise at the following quote from one of your prior posts (bolding mine):
Notice how Roman concrete and properly mixed concrete gets harder and harder over time, until the concrete that my great grandfather and grandfather poured is so hard that I can't drive a nail into it, while the common albinile-hand-mixed home-made-up-formula concretes do not cure properly, have a lot of unnecessary efflorescence, are weak, and get weaker over time vs. stronger over time.
So, by substituting Cal for cement and by making a soupey slurry to make it easier and faster to handle (less bubbles to have to work out) and much easier and faster to finish - many common guys create a weaker product that does not perform well.
Because it seems odd you wouldn't know that for the Romans and others for centuries that followed, lime was the main ingredient of their cement, concrete and mortar.
Lime mortar was used pretty much exclusively up until Portland cement came along when it was first added to speed up the set time.
Since you are obviously an expert on concrete construction and spent 6 months working with your SIL, and love to make long, linformative posts, explain how a typical house is built here. (Don't go Googling now. That would be like cheating at Solitaire). A step by step explanation. Start us off with the foundation and take us all the way up through the roof. Materials, techniques, different cement and concrete mixes etc. Necessary compression strength, slump testing and a rebar schedule should be included. Some detailed information on the different aggregates used in your area. Include specifics on the workability of your mortars. The different kinds of brick and block plus their differences and properties.
I know I am not alone in anxious anticipation of your response.
P.S. It is spelled albañil
