Performance Attributes

CRACK CONTROL

TOUGHER

FASTER WORK

CRACK CONTROL

• Plastic shrinkage crack mitigation

• High modulus fiber controlling thermal and drying shrinkage
cracking in hardened concrete from thermal and drying shrinkage

• Impact and fatigue resistance

• Increased flexural performance

• Neutral buoyancy and uniform dispersion

• No rust, no staining

TOUGHER

• Multi-filament strand mineral fiber with natural affinity to cementitious materials

• Immediate efficiency starting at small crack opening, LOP and beyond

• Enables wider joint spacing and jointless floors

FASTER WORK

• Replaces the time consuming preparation and installation of steel rebar

• Easy dosing — ready to add to the concrete, either at the ready-mix plant or at the jobsite

• Fast dispersion during mixing

• Low impact on workability

• Easy and trouble-free pumping

• Superior finishability

APPLICATIONS

Anti-CRAK® HP 67/36 is used in slabs-on-ground, pavements, bridge decks, roundabouts, concrete pavement overlays, agricultural slabs, commercial and industrial floors, precast concrete, and other applications designed with low crack openings.

How to Use

It is recommended to add Anti-CRAK® HP 67/36 at the mixer into wet concrete during the last stage of mixing, or directly into a ready mix concrete truck on the jobsite. Mixture proportions and fiber dosage should be verified by testing.

The recommended dosages are:

	THERMAL AND SHRINKAGE CRACKING		STRUCTURAL PERFORMANCE
FIBER TYPE	MACRO		MACRO
ADDITION RATE	kg/m³ 1 - 5	lbs/yd³ 1.5 - 8.5	kg/m³ 5 - 15	lbs/yd³ 8.5 - 25
BENEFIT	Anti-cracking mesh replacement		Structural mesh and steel rebar replacement
PRIMARY APPLICATION	Residential floor, light commercial floors		Commercial & industrial floors, pavements, thin-walled precast

Packaging & Storage

Anti-CRAK® HP 67/36 is packed in plastic bags (5 kg). Anti-CRAK® HP 67/36 should be stored away from heat and moisture, and must stay in its original packaging. Optimum conditions are temperature between 15°C and 35°C (59ºF to 95ºF) and humidity between 35% and 65%. If the product is stored at lower temperatures it is advisable to condition it in the workshop for at least 24 hours before use, to prevent condensation.

Quality Standards

Anti-CRAK® HP 67/36 is manufactured under a quality Management System approved to ISO 9001.

Anti-CRAK® is not classified as dangerous by the Regulation 1272/2008/EC. For more information, please refer to our Safe Use Instructions Sheet.
