Analysis of a range of construction and associated materials to British, European and American standards to a five working day turnaround, shorter time scales are available where possible. Unusual procedures can be accommodated from supplied documentation or our own extensive library.
Shown below are our UKAS accredited tests for each material for our full range click on the picture.

Concrete

• Aggregate cement ratio (cement content).
• Presence of HAC
• Chloride content.
• Sulfate content.
• Sulfide content.
• Alkalis.
• Capillary porosity.
• Original water cement ratio.

Analysis is carried out to BS 1881:Part 124:1988, BRE IS 15/74 and documented in house methods.

The presence of HAC can be confirmed by analysis to BS 1881 with the additional determination of aluminium allowing the calculation of aluminium:silica and aluminium:calcium oxide ratios for comparison with accepted values for OPC and HAC concrete.

Should the presence of ggbs be noted during analysis for cement content the sulfide content can be determined and the correct proportions calculated.

Mortar & Render

• Mix proportions (cement content).
• Sulfate content.
• Iron oxide, aluminium oxide & magnesium oxide content.
• Chloride content.

Analysis is carried out to BS 4551:2005 and BS EN 1015-17:2000

Screed

• Mix proportions.
• Sulfate.

Analysis is carried out to a documented in house method based on BS 4551: Part 2 :1998 (screed was removed from BS 4551 in 2005). Magnesium oxychloride and calcium sulfate based screeds can also be analysed.

Gypsum Building Plasters

• Sulfate & calcium oxide content
• Soluble sodium & magnesium content.
• Loss on ignition.
• Free lime content
• Contamination with cement

Analysis is carried out to documented in house methods based on BS 1191:Part 1 & 2 :1973

Aggregates

• Water & acid soluble sulfate content.
• Water soluble chloride content.
• Total sulfur content.
• Sulfide content.
• Carbon dioxide (carbonate) content.
• Loss on ignition.
