There are researchers looking at the amount of fossil fuel energy required for the transition. One research group is MIT: https://climate.mit.edu/ask-mit/does-concrete-needed-build-renewable-energy-negate-good

Other researchers have estimated fossil fuel budgets that need to be reserved for building the initial renewable energy production infrastructure for the transition.

Research is nonlinear. A recent breakthrough might circularize cement industry:

‘If Cambridge Electric Cement lives up to the promise it has shown in early laboratory trials, it could be a turning point in the journey to a safe future climate. Combining steel and cement recycling in a single process powered by renewable electricity, this could secure the supply of the basic materials of construction to support the infrastructure of a zero emissions world and to enable economic development where it is most needed.’ http://www.eng.cam.ac.uk/news/cambridge-engineers-invent-world-s-first-zero-emissions-cement
