Eco-cement is a special kind of cement that is made in a way that is good for the environment.
Normal cement is made by heating up special rocks and minerals to very high temperatures. This creates a lot of pollution because it takes a lot of energy to heat the rocks up so much.
Eco-cement is made differently. Instead of heating up rocks and minerals, eco-cement is made by recycling things that we already use every day. For example, it can be made from recycled concrete, glass, and even plastic!
The best part about eco-cement is that it doesn't pollute as much as normal cement. This is because it uses less energy and doesn't release as much harmful gases into the air.
Overall, eco-cement is a really good thing because it helps us build things without hurting the environment as much.
