What is BS 8615‑1 - Specification for pozzolanic materials about?
BS 8615 is the European standard on pozzolanic materials used in cement for building construction.
BS 8615‑1 is the first part of the BS 8615 series of documents that specifies requirements for the production, chemical composition, mechanical and physical properties of pozzolanic materials for use in combination with Portland cement class 42.5 N or greater, conforming to BS EN 197-1:2011, as a component of concrete, mortar or grout.
NOTE: BS 8615‑1 covers the following types of pozzolana:
- Natural pozzolana (P) as defined in BS EN 197-1:2011, 5.2.3.2
- Natural calcined pozzolana (Q), (excluding high reactivity natural calcined pozzolana conforming to BS 8615-2), as defined in BS EN 197-1:2011, 5.2.3.3.
Who is BS 8615‑1 - Specification for pozzolanic materials for?
BS 8615‑1 on the specification for pozzolanic materials is applicable to:
- Manufacturers of cement and concrete
- Civil engineers
- Builders
Why should you use BS 8615‑1 - Specification for pozzolanic materials?
Pozzolans are silicate-based materials that react with the calcium hydroxide generated by hydrating cement to form additional cementitious materials.
BS 8615‑1 provides the chemical and physical requirements of pozzolanic materials for use with Portland cement.
8615‑1 navigates you through the necessity marking, provision of information and conformity criteria for the manufacturer’s auto control system.
With 8615‑1, you can utilize quality pozzolanic materials in concrete as partial replacement of cement is gaining immense importance today, mainly on account of the improvements in the long-term durability of concrete combined with ecological benefits ensuring workability, setting time, density, air content, compressive strength, modulus of elasticity and permeability of concrete.
