Cements
for masonry include masonry cement (ASTM C 91) and mortar cement
(ASTM C 1329). They are hydraulic cements designed for use in mortar
for masonry construction. Masonry cement consists of a mixture of
portland cement or blended hydraulic cement and plasticizing materials
(such as limestone or hydrated or hydraulic lime), together with
other materials introduced to enhance one or more properties such
as setting time, workability, water retention and durability. These
components are proportioned at the cement plant under controlled
conditions to assure uniformity of performance.
Mortar cement
is similar to masonry cement, except the specification for mortar
cement includes a bond-strength requirement qualifying the material
for use in high seismic and demanding structural applications.
The workability,
strength, and color of masonry cements and mortar cements stay at
a uniform level because of manufacturing controls. In addition to
mortar for masonry construction, cements for masonry are also used
in portland-cement based plaster construction.
