A.C.P-A

HIGH PERFORMANCE ACCELERATING SILICA FUME GEL

DESCRIPTION

A.C.P-A is an advanced concrete admixture used for designing high performance concrete and multipurpose concrete mixtures. A.C.P-A is based on a highly pozzolanic mineral material which significantly reduces water absorption and permeability of concrete, besides increasing workability and accelerating hydration.

A.C.P-A comprises the following chemicals:

Silica fumes
New generation super plasticizers
Waterproofing agents
Catalysts and fillers

This advanced-technology product meets the requirements of the following standards:

ASTM C1202

BS EN 12390-8, BS 1881-122

Method

DOSAGE

The optimum dosage of A.C.P-A can be determined by trials in the site. Depending on concrete mix design (concrete type, workability, compressive strength, sizes and types of aggregates, cement content, water/cement ratio, ambient temperature and concreting conditions), a dosage between 5.0 and 9.0 percent by cement weight is recommended.

Note: when using A.C.P-A, water-cement ratio must be considered around 0.40.

For using other ranges of dosage, contact ABADGARAN INTERNATIONAL GROUP Technical Services Department.

Please contact our engineering office in case of simultaneous use of more than one admixture.

DIRECTION OF USE

A.C.P-A can be added to concrete in two ways:

1-A.C.P-A could be added to ready-mix concrete before placing concrete.

2-A.C.P-A could be added to a part or whole of concrete mixing water then added to the concrete mix.

Properties

Reduces water-cement ratio.
Reduces cement content in concrete between 15 to 20 percent.
Increases workability and workability retention of concrete.
Achievement of early compressive strength of concrete.
Improves pumpability of concrete and reduces depreciation of concreting equipment.
It can be used with all types of Portland cement.
Possibility of replacement of cement type 2 by cement type 5 when applied.
Increases the compressive strength of concrete about 30%-70%.
Considerably reduces permeability.
Reduces the potential for AAR (Alkali-Aggregate Reaction).
Inhibits chloride ion penetration and any other destructive chemicals influence.

Application

Enables production and transportation of concrete in long distances and cold weather concreting.
Produces High Strength Concrete (HSC) and Water Resistant Concrete (WRC).
Suitable for marine environments or the regions exposed to chemicals attack e.g. southern and northern parts of Iran and saline regions.
Docks, deck bridges, tanks, etc.
Designs of concrete mixes for Water and Wastewater Treatment.
