I'm doing a life cycle analysis type of calculation and would need to compare several products that use concrete; however, the literature sources list either concrete or cement consumption but not both. What would be appropriate values for converting from cement consumption to weight of finished concrete product, or from finished concrete product to cement consumption? I'm interested in average concrete as used globally.
Dear Janne M. Korhonen
I think the following open access articles will provide you with useful information:

You need to first define what is the application of the concrete, form that you can define what mix ratios you would use (1:2:2; 1:2:3, etc) there are even Apps for that. Depending on how you calculate them you will get the cement amount either on mass or volume, on which case you use the cement density to calculate its mass. On the ecoinvent database( https://www.ecoinvent.org/database/database.html) , you will get many LCIs with the mix designs for different concrete applications, products and geographies.
You can prepare a proper mix design depending upon the strength reqirement of your project.
I have tried to establish a similar ratio in an open access paper before. You can take a look at it and check its suitability.
