Concrete testing to new Irish Standard I.S. 465:2018

Concrete testing to new Irish Standard I.S. 465:2018

Petrolab has completed its first tests carried out in accordance with this recently published Irish Standard. I.S. 465:2018 is concerned with the assessment, testing and categorisation of damaged buildings made with concrete blocks containing certain deleterious materials (excessive quantities of free muscovite mica or pyrite) in Co. Donegal and Co. Mayo. The problem is similar in many respects to that of ‘mundic’ concrete degradation in the sout-west of England, and the petrographic examination requirements of the new I.S. draw upon those developed for the RICS Mundic Guidance by Petrolab and other petrographers. Petrolab is pleased to be able to apply its considerable 25 years+ experience in examination of ‘mundic’ concrete to look at this new...
Job Opportunity – Software Engineer

Job Opportunity – Software Engineer

We currently have a temporary position available for an experienced Software Engineer. MAIN PURPOSE The postholder will work to continue the development of version 2 of a reporting application for the Carl Zeiss Microscopy Mineralogic Mining system. This is a temporary post with an expected project duration of approximately 2 months (full-time), though possibly longer. PROJECT BACKGROUND A WPF/ C#/ SQLite reporting application to be used to summarise, view and compare large mineralogical data sets produced by automated mineralogy using a scanning electron microscope and the Zeiss Mineralogic system. Data comes from analysis of a mineralogical sample (or samples) and consists of data on particles, made up of one or more grains. Each grain / particle has shape (morphometric) and composition (elemental) data. The overall goal of the reporting application is to streamline the workflow for calculating and producing summary project output (in the form of custom tables, charts and images) from Mineralogic output data in a reproducible and efficient manner. For more information and to apply, please e-mail petrolab@petrolab.co.uk to request an application...
RICS Mundic Guidance 3rd Edition

RICS Mundic Guidance 3rd Edition

The long awaited 3rd edition of the RICS guidance note – The mundic problem – took effect from 1 January 2016. Petrolab Director John Fletcher was involved in revising the section on petrographic testing procedures and thinks that while the revised procedures do not invalidate any of the tests carried out under the 2nd edition of the guidance, they do provide more flexibility for the petrographer in concrete classification by the use of the dry density test and by re-grouping of certain types of stable mine waste aggregate by the Stage 2 examination procedure.  More details on mundic testing can be...
