New page Alternatives to Cement

edit

There are quite a few more alternatives to cement than are listed in the section here. I think it justifies its own page. Nellas Galadhon (talk) 18:47, 14 August 2021 (UTC)Reply

Please add them here then propose a split Chidgk1 (talk) 14:26, 27 April 2023 (UTC)Reply

Not exclusively roman

edit

We have example of hydraulic cement after the fall of Rome and before the advent of Portland cement. In Znachko-Iavorskii, I.L., New Methods for the Study and Contemporary Aspects of the History of Cementing Materials. Technology and Culture, Vol. 18, No. 1, 1977 the author describes a great deal of hydraulic lime mortar from all over the world before and after the fall of Rome, made from a startling variety of materials - things like egg whites, cheese and sour cream were used to achieve it. He has recipes from the high medieval period, and analysis of 11th century mortars that could set under water. These were not "weak pozzolans" - in many cases the different regional variations of hydraulic cement were superior to imported Portland cement in the 19th century. — Preceding unsigned comment added by 80.167.95.143 (talk) 19:17, 2009 January 30 (UTC)

Environmental segregation and union

edit

The article on Environmental impact of concrete repeats a lot of the content in this article, in the section on cement and environmental impact. I propose that that article be changed to Environmental impact of cement and concrete and that the substance of the matching section of the cement article be moved out and suitably united with the new article, together with any other material in other articles that match. I'd be willing to help if desired. Any comments? JonRichfield (talk) 12:12, 15 March 2013 (UTC)Reply

Don't know if you are still around Jon. Possibly interested Nellas Galadhon (talk) 18:45, 14 August 2021 (UTC)Reply

Water Restive?

edit

The article currently refers to some cements as having poor "water restive" qualities. Is that meant to be "poor water resistance"? Because in modern English "restive" means something like "impatient". IAmNitpicking (talk) 20:20, 20 April 2017 (UTC)Reply

Cement#CO2_emissions

edit

Shouldn't we mention Carbon8 Aggregates, CarbonCure and perhaps Solidia Technologies here ? It doesn't subtract CO2 from the environment (or at least I don't think so) but the first makes building materials by using the CO2 from the environment, the second one sells a system to inject CO2 into concrete and the last is a type of concrete that traps CO2.

Also maybe stuff from https://www.lc3.ch/ and https://www.carbonbrief.org/qa-why-cement-emissions-matter-for-climate-change if someone has time to do it.Chidgk1 (talk) 07:06, 21 March 2019 (UTC)Reply

Why does Greece have to be in the same section with Rome..

edit

Let's separate those two. People shouldn't always associate Greece with the Romans and vice versa. Onoufrios d (talk) 11:12, 22 August 2023 (UTC)Reply

No need for separation. They are together in this section because both employed pozzolans to produce hydraulic cement and concrete. Plantsurfer 11:37, 22 August 2023 (UTC)Reply
