Modelling recycled water in concrete

Oliver7025 February 9, 2023 at 8:54 pm

Hi there eTool community,

Hey can anyone explain how I can model concrete with a certain % of recycled water content?

Also does this have any meaningful effect on reducing carbon?

Many thanks

Hi Oliver,
I’ve found this public template in the eTool library that explains how to model concrete with a certain % of recycled water content: Poured Concrete – External Works, Paving, 25MPa, 50% BFS, 50% Recycled Water, 30 year Service Life (m3).
Here is the link: https://etoollcd.com/Library/Template/Index/42272
In this template, recycled water is modelled as a -(ve) quantity of fresh water. Note that this is for reduced fresh water usage and not a carbon saving (carbon impact is not modelled accurately, but is not significant).
For more information about modelling custom concrete mixes, this support post may be useful: https://support.etoollcd.com/index.php/knowledgebase/modeling-custom-concrete-mixes/

Best,
Alice
