Q&A: Why cement emissions matter for climate change

Around half of the emissions from cement are process emissions arising from the reaction above. This is a principle reason cement emissions are often considered difficult to cut: since this CO2 is released by a chemical reaction, it can not be eliminated by changing fuel or increasing efficiency.

Concrete Grinding Residue: Its Effect on Roadside

Concrete grinding residue (CGR) is a slurry waste consisting of water and concrete fines generated from diamond grinding operations that is used to smooth a concrete pavement surface. During this process, CGRs are mostly disposed along the roadside, which can influence soils and plant communities along the roadways.

Construction Causes Major Pollution. Here's How We Can

Aug 20, 2020 Each ton of cement is combined with 6 or 7 tons of sand or gravel; the cement is the structural “glue” that holds the sand together. Sand mining can have devastating repercussions for communities, both due to land erosion as well as from air pollution. Illegal sand mining is common, leading to unchecked environmental destruction.
