After caving in ancient underground fort casements and massive magazines of
turn of the century coastal defenses I stumbled across some old ledgers in
the dust of what used to be the fort engineers office..
The old faded yellow paper half eaten by moth and mice reads
. Dated "June 30 1898" We are using Beach Brand Rosendale cement an(d?)
,Largerdofer Portland cement for the forts construction.........Ah ha! ...but
.Later on in 1903 there is an invoice for Laurenceville cement ......and they
documented using beach sand in the mix ( a no no)
.......any takers or libraries on what Rosendale and Laurenceville are ???
Hydraulic Lime mortars (yes?) perhaps Roman(natural) cements.?... pulling my
hair after Hogmonay Michael...
