Mid-Range Water-Reducing Admixture for Concrete Product Description

CATEXOL 3500 N is a mid-range plasticizing admixture designed to meet the performance requirements of specialty concretes. CATEXOL 3500 N is specifically formulated to dramatically enhance finishability while providing a normal rate-of-set in mixes with a high pozzolanic content (fly ash, slag, etc.) or a slow-setting cement in cooler temperatures. CATEXOL 3500 N has a unique formulation which provides a wide range of dosage flexibility to adapt to the performance characteristics of your materials and climatic conditions. CATEXOL 3500 N substantially improves the aesthetics of poured walls, provides superior finishability in flatwork while providing an optimum rate-of-set to meet difficult construction schedules.


• Dramatically improved finishing • • • • • • • • • •

characteristics for flatwork. Increased workability and easier placeability. Mid-range water-reducing characteristics. Faster rate-of-set with high pozzolanic content mixes. Easier and faster pumping of concrete. Reduced shrinkage and cracking. Reduces segregation at a given slump. Reduced permeability. Increased concrete durability and uniformity. Improved appearance of architectural concrete. Increased strengths at all ages.


CATEXOL 3500 N contains no calcium chlorides. CATEXOL 3500 N can be used in all types of concrete including plain, reinforced, extruded, precast and prestressed concretes. CATEXOL 3500 N is especially effective in concrete containing such pozzolanic materials as fly ash, silica fume and slag.


The recommended dosage range for CATEXOL 3500 N is 3.0 to 20.0 ounces per 100 lbs. (195 to 1300 ml per 100kg) of cementitious material as an ASTM C 494, Type A admixture. Dosage rates vary depending upon the amount of plasticity and/or water reduction desired. Various concrete materials, slump, ambient air temperature, additions of pozzolanic materials, mixing time, and type and brand of cement will affect dosage rates. It is suggested that trial mixes be conducted in order to determine the required dosage for optimum performance with your concrete components.

Directions For Use

CATEXOL 3500 N can be dispensed into any of the concrete materials except cement, slag or fly ash. Preferably, CATEXOL 3500 N is dispensed into the water.

Health and Safety

Refer to the MSDS for additional health and safety information.


CATEXOL 3500 N is compatible with other Axim admixtures. However, each admixture should be added separately to the mix.

CATEXOL 3500 N is supplied in either 55-gallon (200L) drums, 265-gallon (1000L) totes or bulk delivery.

Applicable Standards

A trained Axim representative is available to assist in the preparation of specifications, and the resolution of concrete problems in the field.

CATEXOL 3500 N meets or exceeds the requirements of ASTM C 494, Type A; and AASHTO M 194, Type A.

Technical Service


CATEXOL 3500 N should be kept from freezing. If accidentally frozen, its properties can be restored by thawing and thoroughly re-mixing by mild mechanical agitation.
