TRANSCRIPT

  • TERNAL® EV needs to be formulated with one or a combination of rapid calcium sulfates such as semi-hydrate, gypsum or rapid anhydrite. Rapid kinetics of dissolution of the calcium sulfate is a key in creating a balanced hydration process that benefits from TERNAL® EV rapid dissolution.

    Choosing the right calcium sulfate / TERNAL® EV ratio allows the engineering of optimum dimensional stability:

    Once the calcium sulfate / TERNAL® EV ratio is set, it becomes the “core binder” for a range of formulations. The range of performance of flooring compounds sought is created by varying the content of the “core binder”. Different levels of performance, from cost effective to high performance, can be easily achieved with a single “core binder”.

    An entire range can be developed as demonstrated in the chart below:

  • Adjustment of the “core binder” content (based on a carefully defined combination of calcium sulfate and TERNAL® EV) allows the achievement of a wide range of performance. The binder content directly impacts each of the criteria that determines the performance of a self-leveling compound.

    FOR FLOORING COMPOUNDS

    Return to service is improved as “core binder” content is increased.

    Coverage time is reduced with increased “core binder” content.

    Long term mechanical strength improves with increased

    “core binder” content.

    Abrasion resistance improves with increased “core binder” content.

    CONTINUOUS AND PREDICTABLE REACTIVITY

    The reactivity, as measured by initial and final setting time, of TERNAL® EV-based binary self-leveling compounds

    increases in a continuous and predictable way with “core binder” content and can be adjusted to a specific

    performance by varying the additives percentage.

    WALK-ON-TIME

    COVERAGE TIME

    MECHANICAL STRENGTH

    ABRASION RESISTANCE

    The walk-on-time decreases when the “core binder” content (based on a precisely defined combination of calcium sulfate and TERNAL® EV) increases as shown in the graph opposite.

    Rapid drying, i.e. rapid crystallisation of water within ettringite, is essential

    to ensure the residual moisture decreases to a sufficiently low level to allow the installation of floor coverings.

    Drying speed increases with the binder content (at constant dosage of mixing

    water), as shown by the amount of bound water after 2 days.

    The level of strength can be easily adjusted by varying the “core binder” content.

    The wear resistance varies also with the “core binder” content. The graph

    displayed above gives the result of weight loss after Taber test (500 Taber cycles

    (H22/1,000g)) for different self-leveling compounds. The abrasion resistance

    of  self-leveling compounds increases with the “core binder” content.

    Fig 4: Evolution of walk-on-time versus “core binder” content variation

    Early compressive and flexural strength both improve as “core binder content” is increased.

    Self-leveling compounds need to achieve specific strengths before lightweight traffic can be allowed.

    Reliable performance during application, across

    a range of floor leveling compounds, is perhaps

    one of the most difficult features to achieve in this

    application. Each leveling compound in a range

    normally needs to be formulated using multiple

    binder components each introducing a significant

    degree of complexity and variability.

    With TERNAL® EV, an innovative calcium

    aluminate binder, drymix producers can

    efficiently develop an entire range of self-leveling

    compounds with reliable and consistent

    performance. Each of these products can be

    developed with a single “core binder” composed

    of a combination of TERNAL® EV and a suitable

    calcium sulfate according to local availability.

    With this “core binder” a wide range of compound

    performance can be created cost effectively and a

    range of self-levelers developed by the adjustment

    of the quantity of “core binder” added to the

    fillers that make up the bulk of typical formulations.

    The usual range of additives should still be used to

    tune specific performance.

    TERNAL® EV based self-leveling underlayments

    and overlayments provide an answer to many

    trends in the flooring products industry. Issues

    such as environmental performance through low

    binder content, ultra fast return to service and the

    creation of high performance materials can all be

    addressed with TERNAL® EV.

  • Adjustment of the “core binder” content (based on a carefully defined combination of calcium sulfate and TERNAL® EV) allows the achievement of a wide range of performance. The binder content directly impacts each of the criteria that determines the performance of a self-leveling compound.

    FOR FLOORING COMPOUNDS

    Return to service is improved as “core binder” content is increased.

    Coverage time is reduced with increased “core binder” content.

    Long term mechanical strength improves with increased

    “core binder” content.

    Abrasion resistance improves with increased “core binder” content.

    CONTINUOUS AND PREDICTABLE REACTIVITY

    The reactivity, as measured by initial and final setting time, of TERNAL® EV-based binary self-leveling compounds

    increases in a continuous and predictable way with “core binder” content and can be adjusted to a specific

    performance by varying the additives percentage.

    MECHANICAL STRENGTH

    ABRASION RESISTANCE

    The walk-on-time decreases when the “core binder” content (based on a precisely defined combination of calcium sulfate and TERNAL® EV) increases as shown in the graph opposite.

    Rapid drying, i.e. rapid crystallisation of water within ettringite, is essential

    to ensure the residual moisture decreases to a sufficiently low level to allow the installation of floor coverings.

    Drying speed increases with the binder content (at constant dosage of mixing

    water), as shown by the amount of bound water after 2 days.

    The level of strength can be easily adjusted by varying the “core binder” content.

    The wear resistance varies also with the “core binder” content. The graph

    displayed above gives the result of weight loss after Taber test (500 Taber cycles

    (H22/1,000g)) for different self-leveling compounds. The abrasion resistance

    of  self-leveling compounds increases with the “core binder” content.

    Fig 4: Evolution of walk-on-time versus “core binder” content variation

    Early compressive and flexural strength both improve as “core binder content” is increased.

    Self-leveling compounds need to achieve specific strengths before lightweight traffic can be allowed.

    Reliable performance during application, across

    a range of floor leveling compounds, is perhaps

    one of the most difficult features to achieve in this

    application. Each leveling compound in a range

    normally needs to be formulated using multiple

    binder components each introducing a significant

    degree of complexity and variability.

    With TERNAL® EV, an innovative calcium

    aluminate binder, drymix producers can

    efficiently develop an entire range of self-leveling

    compounds with reliable and consistent

    performance. Each of these products can be

    developed with a single “core binder” composed

    of a combination of TERNAL® EV and a suitable

    calcium sulfate according to local availability.

    With this “core binder” a wide range of compound

    performance can be created cost effectively and a

    range of self-levelers developed by the adjustment

    of the quantity of “core binder” added to the

    fillers that make up the bulk of typical formulations.

    The usual range of additives should still be used to

    tune specific performance.

    TERNAL® EV based self-leveling underlayments

    and overlayments provide an answer to many

    trends in the flooring products industry. Issues

    such as environmental performance through low

    binder content, ultra fast return to service and the

    creation of high performance materials can all be

    addressed with TERNAL® EV.

  • TERNAL® EV needs to be formulated with one or a combination of rapid calcium sulfates such as semi-hydrate, gypsum or rapid anhydrite. Rapid kinetics of dissolution of the calcium sulfate is a key in creating a balanced hydration process that benefits from TERNAL® EV rapid dissolution.

    Choosing the right calcium sulfate / TERNAL® EV ratio allows the engineering of optimum dimensional stability:

    Once the calcium sulfate / TERNAL® EV ratio is set, it becomes the “core binder” for a range of formulations. The range of performance of flooring compounds sought is created by varying the content of the “core binder”. Different levels of performance, from cost effective to high performance, can be easily achieved with a single “core binder”.

    An entire range can be developed as demonstrated in the chart below:
