AB  - The blended cement containing pozzolan have
developed in America, Japan and many European
countries. In recent decades, the blended cement
consisting of by products such as fly ash has been
developed by national cement factories. One of a blended
cement made in Indonesia cement plant is Portland
Composite Cement (PCC). At present in Indonesia the
majority of construction works use PCC.Many mass
concrete structures such as dams are currently being built
in Indonesia with use PCC as binder. One important
factor is the variation in the high temperature at the early
age of the mass concrete after pouring. The strength
development at early age of the mass concrete caused by
the hydration heat generated from the blended cement
such as PCC was a focus in this study. After fresh
concrete was poured into a 1.2×1.2×1.2 m mass concrete,
the temperature inside was measured to study the thermal
heat produced by PCC hydration. In an effort to
understand the relationship of thermal heat with the
strength of mass concrete at an early age at the age of 3
and 7 days core specimens were taken to be tested for
compressive strength and indirect tensile strength. From
the results of testing it can be seen that the development
of compressive strength and indirect tensile strength from
3-7 days in 1.2×1.2×1.2 m of mass concrete using PCC
can be attributed to the hydration and interface binding
process on aggregates and cement paste has been going
well even though it has experienced a high temperature of
61.5°C.
