Solution
Lower-clinker cement
Cement blends that replace part of the clinker with other materials, cutting the emissions of making it.
Materials such as calcined clay, limestone or industrial by-products take the place of some clinker in the mix.
Trialling lower-carbon cement
Testing cement blends that use less clinker in a real building, alongside conventional mixes.
Context
Most of cement's emissions come from making clinker, so using less of it is one of the most direct routes to cutting them.
What the work involves.
Step 0101
Specify
Agree test blends and strength targets with engineers and the supplier.
Step 0202
Pour
Use the blends in chosen parts of the structure, beside conventional concrete.
Step 0303
Test
Track strength, curing time and durability against the conventional mix.
Considerations
What it has to weigh up.
- 01
Building codes and approval for new mixes.
- 02
Curing time on a busy construction programme.
- 03
Supply of the alternative materials.
