Part 5:
External concrete coatings
1 Scope
This document specifies the requirements for qualification, application, testing and handling of
materials required for the application of reinforced concrete coating externally to either bare pipe or
pre-coated pipe for use in pipeline transportation systems for the petroleum and natural gas industries
as defined in ISO 13623.
The external application of concrete is primarily used for the negative buoyancy of pipes used in buried
or submerged pipeline systems and/or for the mechanical protection of the pipe and its pre-coating.
This document is applicable to concrete thicknesses of 25 mm or greater.

7 Materials
7.1 Pipe
The supply of bare or pre-coated pipe to be concrete coated shall conform to the pipe and pre-coating
standards or specifications that are specified in the purchase order.
ISO 21809-5:2017(E)
IMPORTANT — Pre-coated steel pipe might not necessarily have a surface condition that is
appropriate for the application of concrete coating. Remediation of the bare steel pipe or pre-
coating may therefore be required.
7.2 Cement
The applicator shall use cement that is:
a) certified by the supplier to be in compliance with the requirements of ASTM C150, ASTM C595,
ASTM C1157 or EN 197-1;
b) identified with the following information on the certification and/or delivery documents for each
shipment of cement:
— cement producer’s name and location,
— product description including type and classification of cement, and
— year and month of production;
c) handled, transported and stored prior to use, in compliance with the cement manufacturer’s
recommendations and in compliance with the applicable standards;
d) no more than 6 months from the date of manufacture for bulk cement or 3 months from date of
manufacture for bagged cement, unless it is retested and proven to be in compliance with the
original standard.
NOTE Cement stored in a warm, humid environment for an extended period of time could possibly lose
significant properties.
For submerged service conditions using concrete mixes containing Portland cement as the only
cementitious material, the tricalcium aluminate (C A) content of the cement shall be less than or equal
to 10,0 %. For all other service conditions, the tricalcium aluminate content limit is not applicable.
For submerged service conditions using concrete mixes containing Portland cement as the only
cementitious material, the alkali content shall not exceed 0,6 %, if potentially reactive aggregates
are used.
7.3 Supplementary cementitious materials
If approved by the purchaser, the applicator shall use SCMs that are:
a) certified by the supplier to be in compliance with the requirements of ASTM C618, ASTM C989,
ASTM C1240, EN 450-1 or EN 13263-1;
b) identified with the following information on the certification and/or delivery documents for each
shipment of SCMs:
1) SCM producer’s name and location,
2) product description including type and classification of SCM, and
3) year and month of production;
c) handled, transported and stored prior to use, in compliance with the SCM supplier’s
recommendations and in compliance with the applicable standard;
d) within time limits stated in the applicable standard, unless it is retested and proven to be in
compliance with the original standard.
NOTE SCMs stored in a warm, humid environment for an extended period of time could possibly lose
significant properties.
