Lime generates roughly 25% of the carbon that Portland cement does in production,and then slowly reabsorbs that carbon as it cures. Limestone (what lime is made of) is also extremely abundant on Earth. Seeing as Portland cement is currently the second largest emitter of CO2 into the atmosphere after fossil fuels, we could do with using a lot more lime and a lot less Portland.
If you want to learn how to use lime in a host of different ways, the All About Lime Course will show you the way.

When Might Lime Not Be Suitable?
1. Applications where the lime spends a lot of time submerged in, or being hit by water: Shower floors, water tanks, swimming pools etc may fail. I have seen lime work for a shower floor with tiles and grout, and a water tank, but it's a bit hit and miss. If you need a waterproof crete, this is the one time I'd say Portland cement is more appropriate.
2. Lime renders, mortars and cretes are always softer and more porous than Portland cement, so any application where you definitely need a rock solid, tough as nails, impermeable surface, lime may not be suitable for.

Hi! I'm Atulya. I've been living off-grid and building with mud for nearly ten years now. My love of natural building arose from nowhere. Back in 2011 I was living in a field in Turkey. Bit by bit, out of necessity I taught myself to build with mud. It became a creative passion. Within a year I had constructed a house. A year later I installed solar power. I have been in nature, mud building and writing about it ever since.
Today I am founder and author of The Mud Home natural building and off-grid freedom website. I also write about natural building for publications such as Mother Earth News and the Owner Builder Magazine.
