cementitious materials for concrete standards, selection

Cementitious materials for concrete are fine mineral powders. When these materials are mixed with water, they react chemi-cally to form a strong rigid mass that binds aggregate particles together to make concrete. The cementitious materials dealt with in this leaflet are all based on portland cement and many contain a “cement extender.” This publication gives information on the standards

Secondary cementitious materials include fly ash, ground granulated blastfurnace slag (GGBS), limestone, silica fume, natural pozzolana and natural calcined pozzolana. Fly ash and GGBS are the most commonly used of these materials in the UK. These secondary materials are useful by-products of other industrial processes.

Standards for cement, aggregates, admixtures

Cements (for use in concrete) are factory-produced materials produced by either inter-grinding or blending their constituents at the cement works. They conform primarily to the British/European Standard BS EN 197-1. Some cements, such as sulfate-resisting Portland cement (SRPC) are however still covered by residual British Standards.

Cement Standards and Concrete Standards

ASTM's 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.

The concrete produced using alkali-activated cementitious materials (AACM) can have performance benefits such as improved chemical and fire resistance and/or lower permeability to water and aggressive agents. However, these new AACM products are not fully covered in other British Standards for cement and concrete.

What is Concrete

Cementitious Materials 'Cement’ generally refers to the powder component of concrete which, when mixed with water, becomes the glue-like material, or binder, that allows concrete to set, harden and strengthen. These materials include Portland cement, fly ash, ground granulated blastfurnace slag (GGBS), limestone fines and silica fume.

Concrete is a mixture of hydraulic cement, aggregates, and water, with or without admixtures, fibers, or other cementi tious materials. Aggregates are granular materials such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag. Coarse aggregate is that portion retained on the 4.75 mm (No. 4) sieve.

How to mix cement to make mortar or concrete Marshalls

For a standard mortar mix this normally on a ratio basis (usually around 3 or 4 parts building sand to 1 part cement) recommendations vary but you don’t want the mixture to be too wet or too dry. In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts
