Cite your sources for others to review. I know you are probably using one of the multiple mormon sites for this info. However, if you bother to read Hyman’s original document, instead of the citations that are cherry picked from his 1970 paper, one will note that this ‘cement’ was nothing more that a mixture of limestone that was used for mortar and stucco. There is nothing that has been found of buildings constructed completely from ‘concrete’.
Second issue, this location at Teotihuacan the temple was constructed from stone, with this stucco finish. Again, misrepresenting the facts of the matter.
Finally, there is absolutely nothing at this site that is hebrew, egyptian or any resemblance of the form of worship depicted in the bom.
