OVERVIEW

This is an introduction to the family of current EN standards relating to the design of concrete structures and the former British standards they replaced. The new single standard covers 27 types of common cements and 7 types of sulfate resisting cements that replace different individual British standard on common cements. Join this session to learn topics including:

• Conformity criteria for strength class and heat of hydration
• Supplementary cementitious materials (fly ash, ggbs and silica fume) as additions
• Chemical admixtures (plasticisers and set-retardation) specification and testing
• Aggregate grading and properties as categories and their requirements
• Fineness and fines content in fine aggregate
• Crushed concrete aggregate (CCA) and recycled aggregate (RA)
• Minimizing the risk of damaging alkali-silica reaction in concrete
