You may wonder why we don't use Roman concrete today if that is the case; well, one of the reasons as to why is because, although it gets stronger over time and withstands erosion from water, when this cement is still young and has not had time to develop its strength from seawater, it likely does not have the ...
How do you make concrete without cement?
No, because the strength-forming matrix of hydrated cement would never be strong enough to be used for building anything. Sure, you could mix some cement with water and soil and it will harden, but it will be very brittle and not stay together.
Why don't we make concrete like the Romans?
Decomposed Granite
This type of gravel is ground into fine particles and will pack together to form a gravel that hardens like concrete when compacted. Decomposed granite has suitable drainage properties for hardscaping, however, it's not capable of draining water fast enough during high-volume rainfall.
Can you make concrete with dirt?
For example, blast furnace slag, a by-product of steel manufacturing, can be used as a partial replacement for cement, reducing carbon emissions associated with cement production. Another approach to carbon-negative concrete involves the capture and storage of CO2 emissions during the manufacturing process.
