Descriptioon
EGB Pozzolanic Binder is designated in the British Standard for cement ( BS EN 196-1 : CEM 11 / B-Q ). This designation covers cement containing between 55% and 68% Portland cement clinker, 32% and 45% EGB Pozzolanic material and 0.5 - 1.5% minor additional constituents.
EGB Pozzolanic Binder is manufactured by blending and inter grinding the various constituents to produce a homogeneous product. It is subject to the same rigorous production control as all others BS EN 196-1 cement with independent third-party verification and carries SIRIM Certification Standard.
Application
EGB Pozzolanic Binder is based on siliceous material and is recommended as an alternative to Ordinary Portland Cement in the following applications:
-
For general purpose concreting.
-
To reduce chemical attack on concrete in aggressive ground conditions.
-
To minimize the risk of ASR in concrete containing high-reactivity aggregates or recycled aggregates.
-
EGB Pozzolanic Binder has a certified low heat of hydration. This is highly beneficial for concrete used in large pours, where it can help to reduce the risk of early-age thermal cracking.
Properties
EGB Pozzolanic Binder concrete, when compared to Ordinary Portland Cement concrete at the same cement content, has the following properties:
-
Slower early-strength development, but potentially higher long term strength.
-
The appropriate cement content for concrete of a given 28 day cube strength and slump should be determined from trial mixes.
-
Extended setting, particularly in cold weather.
-
Reduced bleed.
Packaging
Availability
EGB Pozzolanic Binder is available in bulk and 50kg/bag.
Condition of Use
-
Can be used for most applications.
-
