Product Data Sheet

Description:

IPANEX is an admixture to waterproof concrete and provide corrosion control. It is a complex alkaline earth silicate admixture that chemically reacts with portland cement to improve the physical and chemical properties of concrete in all stages of development – fresh, curing and finished concrete.

IPANEX is used to reduce the permeability of concrete in above and below grade applications, to provide concrete with greater durability in structures that are historically subject to accelerated deterioration and to provide resistance to reinforcing steel corrosion.

Typical applications include parking structures, below grade walls and floors, water and wastewater treatment plants, underground vaults, tanks and pits, swimming pools, pressure mats, water storage tanks, tunnels, bridge structures (precast and cast-in-place), curbs and gutters, sidewalks, manholes, catch basins, highways, water parks, monuments, runways and dams.

The effects of IPANEX concrete admixture include:

Permeability Reduction

The most water soluble constituents, calcium hydroxide and calcium aluminum hydroxide (referred to as free lime) are converted into the insoluble minerals, tricalcium silicate and tricalcium-aluminum silicate. These insoluble minerals precipitate into the capillaries as very fine micro-crystals. Combined with the micro-pore structure, this results in a concrete mass which can withstand the penetration of water, even under extreme pressures.

Increased Durability

Large numbers of the macro-pores (found in conventional concrete) are reduced in size to micro-pores in IPANEX concrete. Approximately 3.8% of the cured mass of IPANEX concrete is occupied by these micro-pores. The micro-pores are hydrophobic and even though the system “breathes”, condensation cannot form. This factor, combined with other physical properties of IPANEX concrete, results in a matrix that is extremely durable under the most severe conditions.

Corrosion Resistance

Independent field evaluations and laboratory testing show that IPANEX concrete protects reinforcing steel from corroding.

Advantages:

In the Fresh Concrete State –

Contains no calcium chloride (or other chlorides)
Lower slump concrete is more easily mixed, placed and consolidated
Highly cohesive, eliminating voids and honeycombs
Bleed-water is reduced, providing for earlier finishing
Excellent workability when floating or troweling
Easily pumped
Minimizes segregation

In the Curing State –

Significantly reduces drying shrinkage
Lower controlled heat of hydration

In the Hardened State –

Higher compressive strength (slump for slump and equal air content)
Positive effect on all physical properties
Watertight under hydrostatic pressures up to 7 atmospheres – more than 100 psi (689.5 kPa). Forms a completely watertight mass
Hard durable surfaces are resistant to dusting and spalling
Surfaces are also highly resistant to cavitation and abrasion
Eliminates formation of condensation in the pore matrix, resulting in excellent freeze-thaw resistance
Inorganic material providing anti-bacterial and anti-fungal properties
IPANEX reduces efflorescence and exhibits increased resistance to chloride ion penetration
Cannot wear off like a coating

The following is a partial summary of tests made on IPANEX concrete:

Permeability of conventional concrete as compared to concrete containing IPANEX admixture, F’c = 4,000 psi (27.6 MPa). Based on modified CRD C 48-55 test procedure. Depth of penetration by water was reduced by 84%. Volume of penetration by water reduced 98%.
Compressive Strength, psi, ASTM C 39 – Minimum 110% of control – 3, 7, 28 day strengths all greater than control (equal air and equal slump)
Flexural Strength, psi, ASTM C 78 – 3, 7, 28 day strengths all greater than control (equal air and equal slump)
Length Change, ASTM C 157 – IPANEX concrete exhibits approximately 25 percent less shrinkage than control concrete (equal air and equal slump)
Bond developed with reinforcing steel, psi, ASTM C 234 – minimum 105% of control, 28 day tests
Heat of Hydration, cal./g., ASTM C 186 – IPANEX concrete exhibits 13% less heat of hydration
Capillary Water Intake, % – IPANEX concrete exhibits 48% of control at ½” (12.7 mm) submersion and 44% of control at 5½” (139.7 mm) submersion
Freeze -Thaw Durability, AASHTO T 161, 300 cycles – 101.2% of control
Resistance of Concrete to Chloride Ion Penetration, AASHTO T 259-78/T260-78 – 75% greater than control
Reduction in Expansion from Alkali Silica Reaction, %, ASTM C 441 – 47% less expansion
Macrocell corrosion test (SCAT) – after 48 weeks of alternate cycles of 4 days of 15% NaCl ponding and 3 days at 100°F (37.8°C) drying of IPANEX modified concrete, the corrosion currents, half cell potentials, and chloride ion contents were all below established corrosion thresholds. After 48 weeks the slabs were demolished and no corrosion of reinforcing steel was evident.

Installation:

IPANEX admixture is added to the concrete at the job site, batch plant, or pre-caster’s facility.

Check design mix to specification to confirm proper dosage of IPANEX
Premix IPANEX. Continue mixing until a uniform consistency is achieved.
Dispense IPANEX into the concrete truck or batch plant mixer at proper dosage.
Mix IPANEX in the truck by spinning the barrel at maximum mixing speed for 5 minutes.
Mix IPANEX at batch plant in accordance with plant procedures.
Insure that convenience water is not added. Over addition of water will negate beneficial effects of IPANEX .
