Chimney Cap/Crown mortar that will not crack?

Hi All,
Had a guy repair the top of my chimney including a new cap. A week later I
get on a roof and the cap/crown is already cracked. Had the guy leave a gap
between the crown and the flues (2), so I can fill it with flexible sealant,
but that apparently did not help. I live in the Midwest.
Can anyone point me to a mortar formula for a mortar that will crack in such
a short time? Guy says he used the following:
1 part acrylic to 3 parts water
2 parts sand to 1 part Portland cement
Apparently this is not a good combo.
Regards,
RichK
