I have a number of bags of Blue Circle Mastercrete Cement (the blue and yellow plastic bags) that I bought years ago. They were bought to render my raised driveway but certain events meant this got delayed. I still have the bags stacked up in our lean-to which is in the middle of being insulated and turned into a proper utility room so it’s water tight, doesn’t get damp etc. The bags used by date is Nov 2021, which is obviously a long time ago!
Blue Circle advise against using out of date cement because of health and safety reasons (here), but don’t say anything about its actual usage and effectiveness. The cement is still earmarked to be used for rendering, so are they still ok to use? I haven’t opened any up, they’re all still sealed, so I don’t know the condition. What should I look for, and if all being well can I still use them for this application? Thanks
