FOREWORD
This Indian Standard ( Part 2 ) ( Third Revision ) was adopted by the Bureau of Indian
Standards after the draft finalized by the Cement and Concrete Sectional Committee had been
approved by the Civil Engineering Division Council. Portland-pozzolana
pozzolana cement can be
produced either by grinding together Portland cement clinker and pozzolana with addition of
gypsum or calcium sulphate, or by intimately
intimat
and uniformly blending Portland cement and
fine pozzolana. While grinding of the two materials together presents no difficulty, the
mixing of dry powders uniformly is extremely difficult. The blending method should,
therefore, be resorted to only when the grinding method is impossible or proves
uneconomical in a particular case. Where blending method is adopted, every care should be
taken to see that the blending is as intimate as possible. Generally, if the blending is not
uniform, it is reflected in the
he performance tests. The Sectional Committee responsible for the
preparation of this specification is of the opinion that the blending method should be confined
to factories and such other works where intimate and uniform blending is feasible with the
employment
loyment of requisite machinery so as to ensure uniformity of production and guaranteed
performance. Portland-pozzolana
pozzolana cement produces less heat of hydration and offers greater
resistance to the attack of aggressive waters than normal Portland cement. More
Moreover, it
reduces the leaching of calcium hydroxide liberated during the setting and hydration of
cement. It is particularly useful in marine and hydraulic construction and other mass concrete
structures. Portland-pozzolana
pozzolana cement can generally be used wherever
ever 33 grade ordinary
Portland cement is usable under normal conditions. However, it should be appreciated that all
pozzolanas need not necessarily contribute to strength at early ages. In view of this fact, this
present specification has been prepared to enable manufacturers to produce Portland
Portlandpozzolana cement equivalent to 33 grade ordinary Portland cement on the basis of 3, 7 and
28-days compressive strength. For construction of structures using rapid
pid construction
methods like slip form construction, Portland pozzolana cement shall be used with caution
since 4 to 6 h strength of concrete is significant in such construction. This standard was first
published in 1962 and subsequently revised in 1967 and 1976. In this revision the standard
has been split into two parts based on the pozzolana used in the manufacture of such cements
in view of the special needs of some hydraulic structures which require pozzolana cement
manufactured only with fly ash pozzolana and for easy identification of pozzolana used in the
manufacture of Portland-pozzolana
pozzolana cement in the interest of consumers. Part 1 of this
standard covers pozzolana cement manufactured by using only fly ash pozzolana and Part 2
covers pozzolana cement manufactured by using either calcined clay or a mixture
mixture of calcined
clay and fly ash as pozzolana. In this revision both chemical and physical requirements have
been kept the same as was given in 1976 version of this standard as amended from time to
time. Various requirements of Portland
Portland-pozzolana cement given
ven in 1976 version of this
standard had been modified from time to time by issuing amendments based on the
experience gained with the use of the standard and the requirements of the users and also
keeping in view the raw materials and fuel available in the
the country for manufacture of cement
The important amendments include lowering the value of compressive strength in lime
reactivity test from 5 MPa to 4 MPa, incorporating a value of 3 day compressive strength as
16 MPa, modifying the requirement of sulphur
sulphuric
ic anhydride ( SOs ) and insoluble residue,

B- 1.2 (See

SECTION 1: PRODUCT DESCRIPTION
1.1. Description of product: The Portland Pozzolana Cement is a kind of Blended Cement
which is produced by either inter grinding of clinker along with gypsum and pozzolanic
materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic
materials separately and thoroughly blending them in certain proportions.
Portland Clinker
Clinker, consisting mostly of calcium silicates, obtained by heating to incipient fusion, a
predetermined and homogeneous mixture of materials principally containing lime ( CaO )
and silica ( SiO2 ) with a smaller proportion of alumina ( Al 2O3 ) and iron oxide ( Fe 203 ).
Pozzolana
An essentially silicious material which while in itself possessing little or no cementitious
properties will, in finely divided form and in the presence of water, react with calcium
hydroxide at ambient temperature to form compounds possessing cementitious
ous properties.
The term includes natural volcanic material having pozzolanic properties as also other natural
and artificial materials, such as diatomaceous earth, calcined clay and fly ash.
