PACE-PTS Pan-African Cement Proficiency-Testing-Scheme


General information

The Pan-African Cement Proficiency Testing Scheme (PACE-PTS) is a joint cooperation between the BAM Federal Institute for Materials Research and Testing and the German Metrology Institute (PTB). It gives opportunity for public and private laboratories to self-assess their laboratory performance and to increase their network and skills due to a supplementary workshop and training module. After 2012 the PACE-PTS in 2014 is the second Africa-wide proficiency testing scheme. It is funded within the framework of the German Development Cooperation.

Background

The cement PT scheme was set up in 2012 with the aim of establishing a cement-testing network for Africa. Testing the quality of cement is an important task in order to ensure the safety of construction. PTs are evaluations of participants’ performance against pre-established criteria by means of inter-laboratory comparisons. Proficiency tests are a precondition for accreditation to ISO/IEC 17025.

Participants

37 laboratories from 23 African and 2 European countries have registered for the 2014 proficiency testing scheme. Private and public laboratories in Africa involved in cement testing, and which are competent to analyse the fundamental physical and chemical properties of cement, are encouraged to participate. The costs for the participation in the PT scheme differ in price between public laboratories (universities and government) and private laboratories (see Fees below). The final workshop will be open for all participants. Funding for the workshop (excluding registration fee, as seen below) is available for participants coming from public laboratories.

Scope

The PACE-PTS on 2014 will cover testing of the most relevant physical and chemical properties of cement as listed below:

Test item Specification
Loss on Ignition EN 196-2:2013
Insoluble residue EN 196-2:2013
Chloride content EN 196-2:2013
Sulfate content EN 196-2:2013
Specific surface (Blaine) EN 196-6:2010
Standard consistence EN 196-3:2005
Initial setting time EN 196-3:2005
Final setting time EN 196-3:2005
Flexural strength after 2 and 28 days EN 196-1:2010
Compressive strength after 2 and 28 days EN 196-1:2010
Sieving of sand and aggregates EN 933-1:2012

The optional investigations included the following

Test item Specification
Soundness EN 196-3:2005
Flexural strength after 7 days EN 196-1:2010
Compressive strength after 7 days EN 196-1:2010

The required raw materials (cement, sand, extra items) will be sent out to all registered participants for the analysis. The results need to be submitted by a deadline, which will be fixed as soon as the registration is closed.

After the analysis of the results, each laboratory will receive an anonymised report about the statistical results and an assignment number to identify the individual laboratory’s statistics.

At the end of the PT scheme a final workshop will take place for all participants in the last quarter of 2014 to analyse and discuss the results of the executed tests, with discussions of corrective measures and the way forward. The workshop participation is supported by the funding scheme for public laboratories.

Fees

Public laboratories (Universities and Government): 100 USD including shipping costs
Private laboratories (Industries): 300 USD including shipping costs

After receipt of the registration forms participants will receive an invoice with bank details for payment transfer.

The fees cover shipping of testing materials and the final report as well as the provision of a final workshop including a training module (the location of that workshop will be announced later).

History

As in the 2014 PACE-PTS the testing in the previous proficiency testing scheme was performed according to the European Standards with documented results according to a specified format. The mandatory investigations included the following:

Test item Specification
Loss on Ignition EN 196-2:2005
Insoluble residue EN 196-2:2005
Chloride content EN 196-2:2005
Sulfate content EN 196-2:2005
Specific surface (Blaine) EN 196-6:2010
Standard consistence EN 196-3:2005
Initial setting time EN 196-3:2005
Final setting time EN 196-3:2005
Flexural strength after 2 and 28 days EN 196-1:2010
Compressive strength after 2 and 28 days EN 196-1:2010

The optional investigations included the following

Test item Specification
Soundness EN 196-3:2005
Flexural strength after 7 days EN 196-1:2010
Compressive strength after 7 days EN 196-1:2010
