3D printing technology in concrete construction primarily involves
- AUse of lightweight aggregates
- BLayer-by-layer deposition of concreteCorrect
- CMixing concrete with nanoparticles
- DUsing recycled aggregates exclusively
Solution
Concept
Additive manufacturing of concrete
Step-by-step solution
1. A printer deposits concrete in layers following a digital model.
Explanation
3D printing builds walls layer by layer without formwork.
Why the other options are wrong
The other options are materials issues, not the process.
Shortcut
3DCP = layers, no formwork.
Correct answer: B) Layer-by-layer deposition of concrete
