* Portland cement Types I, II, and III and blended cement Types IS, IP, and I(PM) are also used in making mortar.
** Portland cement Types I, II, and III and blended cement Types IP, I(SM) and I(PM) are also used in making plaster.
*** Portland and blended hydraulic cements are also used for these applications.
cement or blended hydraulic cement and plasticizing mate-
rials (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 propor-
tioned and packed at a cement plant under controlled con-
ditions to assure uniformity of performance.
Masonry cements meet the requirements of ASTM C
91, which classifies masonry cements as Type N, Type S,
and Type M. White masonry cement and colored masonry
cements meeting ASTM C 91 are also available in some
areas. Mortar cements meet the requirements of ASTM C
1329, which also classifies mortar cements as Type N, Type
S, and Type M. A brief description of each type follows:
Type N masonry cement and Type N mortar cement
are used in ASTM C 270 Type N and Type O mortars. They
may also be used with portland or blended cements to
produce Type S and Type M mortars.
Type S masonry cement and Type S mortar cement
are used in ASTM C 270 Type S mortar. They may also be
used with portland or blended cements to produce Type
M mortar.
Type M masonry cement and Type M mortar cement
are used in ASTM C 270 Type M mortar without the addi-
tion of other cements or hydrated lime.
Types N, S, and M generally have increasing levels of
portland cement and higher strength, Type M having the
highest strength. Type N is used most commonly.
