Foreword

This Part of BS 5075 has been prepared under the direction of the Cement, Gypsum, Aggregates and Quarry Products Standards Committee and is based on an initial draft provided by the Cement Admixtures Association. This Part of this standard incorporates such recommendations of other organizations as the Technical Committee felt were usually appropriate, and is based on the results of cooperative tests carried out in accordance with earlier drafts of this Part.

This Part of this standard is concerned only with superplasticizing and retarding superplasticizing admixtures. Accelerating, retarding and water-reducing admixtures are covered by BS 5075:Part 1, and air-entraining admixtures are dealt with in BS 5075 Part 2. Admixtures for mortars are covered by BS 4887.

This Part of BS 5075 specifies acceptance tests which demonstrate the ability of a particular formulation to meet stipulated performance requirements, and admixture uniformity tests which demonstrate that a particular consignment is similar to material which has previously been submitted to the acceptance tests.

No requirements for tests on hardened concrete have been introduced, apart from those relating to compressive strength. Drying shrinkage, creep, and long term durability are still under investigation, and the effect of superplasticizing admixtures on these properties should be the subject of advice from the admixture manufacturer.

Certification. Attention is drawn to the certification facilities described on the inside back cover of this standard.
