Hi all,
I'm into a new build and using Heidelberg cement, because that's what my supplier supplies, and I'm having some mixed results with the quality of the mortar.
Some mixes seem to vary quite a bit from one course to another and some mixes seem noticeably weaker.
Before you ask, I am fairly au fait with a mixer, having spent the past 40 years on the trowel. I use the same mix for all brick & blockwork and haven't come across this variation before, nor such problems.
