cement standards and concrete standards

ASTMs cement and concrete standards are instrumental in the evaluation and testing of concrete cement and aggregates Concrete can have different properties depending upon the mixture that is used in creating it which contains cement chemical admixtures and aggregates These ingredients are mixed with water to create concrete which is used as a primary construction material in buildings

Standards for cement aggregates admixtures EN 197 Cement Cements for use in concrete are factoryproduced materials produced by either intergrinding or blending their constituents at the cement works They conform primarily to the BritishEuropean Standard BS EN 1971

Are there standard specifications for cements A Yes The ASTM Standard Specification for Portland Cement ASTM C150 provides for five types as follows Type IThe standard product that has long been in use with no limitation on the proportions of the major oxides CaO SiO 2 Al 2 O 3 Fe 2 O 3 also referred to as “ordinary portland cement”

Building Codes Safe strong and resilient communities are made possible by building codes that require durable resilient and noncombustible materials like concrete Concrete does not ROT or BURN Building construction in the US is heavily influenced by state and local building codes which are typically based off

Standardization is the most rigorous consensus process used by ACI ACI standards are written in mandatory language There are typically two types of ACI Standards – design codes and construction specifications Design codes are directed to the design professional not the construction team

In addition the standard specifies 6 strength categories in which cements are classified according to their compressive strength of a standard cement mortar according to the standard ELOT EN 1961 Cement testing methods Part 1 Definition of strengths Every strength category is defined by a lower and an upper strength limit

Answer ASTM standards are designed to allow a “meeting of the minds” between the purchaser and the vendor Most project specifications will cite many material standards for the materials that go into making concrete ASTM C150 Cement C618 Fly ash C989 Slag

In general all cements conforming to European Cement Standard EN 1971 are suitable for the manufacture of concrete according to European Concrete Standard EN 2061 Depending on the area of application however differences related to the cement type may possibly have to be taken into account to ensure the durability of the concretes manufactured with these cements
