Folks,

I am trying to find out why masonry cement (MC) is on the market when
portland cement / lime (PCL) mortars appear, at least to me, to perform
better and more reliably?

As many of us know, MC is typically a mix of portland cement, pulverized
limestone and "proprietary admixtures" which manufacturers seldom (never)
will divulge. PCL is portland cement and lime, period.

Can anybody shed light on this for me?

Thanks,

Eric Hammarberg
