DESCRIPTION OF THE MATERIAL
ENT-20 is a special plastic superadditive,
which inhibits and decreases water, and has unique advantages
that allow for the reduction of the amount of cement in the
ENT-20 is a unique additive that our company
in Israel has developed. It is a high quality material for
water reduction, is convenient for use and has every feature
needed in a quality additive for imported concrete.
The advantages of ENT-20 specified below
allow us to resolve the problems referred to in the introduction,
which we all face while planning the mixtures, preparing the
concrete and casting it.
•ENT-20 inhibits the chemical reaction
that begins with the contact of the cement with the water
during preparation of the concrete, and thus delays the decrease
of consistency for 45 minutes (the standard time required
for transporting and casting the concrete). Adding a small
amount of the additive on site will allow for another 45-minute
delay in the decrease of consistency.
• Using ENT-20 will reduce the amount
of water needed for preparation of the concrete with the required
consistency by 15%-20%, and will allow for the reduction of
the cement in accordance with the w/c ratio, without negatively
influencing the required consistency.
• ENT-20 will induce the exit of locked
air from the mixture (created during preparation of the concrete)
and will thus bring about maximal density of the concrete,
which provides several significant advantages: Extra strength.
Waterproof surface area, which is vital in the casting of
basements and pools. The sealing of the concrete prevents
the danger of dampness reaching the constructing iron, which
leads to corrosion.
• ENT-20 allows for a uniform concrete
mixture and maintains the necessary aggregate ranking during
loading, transportation and casting of the concrete.
• The uniform mixture and the completely
dense concrete will let us achieve a nice smooth element with
a uniform surface in the casting of exposed concrete.
• The curing of concrete with ENT-20
is slower and more controlled, thus avoiding the familiar
problem of cracks on hot summer days.
• ENT-20 renders the concrete viscous
and elastic, which makes for easy pumping with the concrete
pumps and prevents blockage of pipes in the pump. The oiliness
of the concrete will also diminish the wear on the pumping
systems and prevent future damages.
• The qualities of concrete with ENT-20
substantially reduce the phenomena of concrete expansion and
contraction under various weather conditions, as well as cracks
and concrete disintegration, thus allowing the concrete to
maintain its strength for many years.
•ENT-20 is characterized by a good
reaction with cement, and it utilizes a bigger portion of
the cement compared to a reaction without the additive. We
thus achieve a strengthening process of the concrete that
is longer than normal.
• The reduction of the amount of cement
in the concrete mixture significantly lowers the cost of theconcrete,
in addition to achieving better concrete.
METHOD OF USE:
APPEARANCE Form: Liquid , Color: Brown.
APPLICATION Solids content: Ca. 37% w/W,
Ash content: Ca. 2% w/W , Relative density: Ca. 1.2%
w/W , Chloride ion content: Nil to 2% w/W , Chloride content
at a dosage rate of 0.28% content: 0.00056% w/W, Equival

Ent-20 is recommended for use at a rate of 400mls -1000mls
per 100kg of cement. (0.4%-1% of cement content). At reduced
dosages water reduction and performance will reduce.
mixes should always be carried out to determine the optimum
dosage rate. For further advice contact the Enermit Technical
Ent-20 should be dispensed into mixer with the gauging
water. It should never be added to dry cement.
Ent-20 can be used with all types of Portland cement.
It is also compatible with other admixtures (i.e. air entrains).
When used in conjunction with other admixtures each must be
dispensed separately into the concrete mix. Please consult
out Technical Department.
This product must be stored in closed containers protected
Ent-20 should be protected in storage against extremes
of temperature. If the product has frozen, thaw at temperatures
above +2 and reconstitute by mechanical agitation only.
18 months in unopened manufacturer containers.
Ent-20 is supplied in 1,000 liter bulk deliveries.
The additive bears a standards mark in compliance with the
strict guidelines of the Israeli standard, and the company
operates in accordance with the European ISO 9001 quality
We have managed to introduce the additive all over the world;
both in Western and Eastern countries, and its advantages
over the other products have been proven.
In addition, our development lab is constantly working on
new technologies and on improving our existing products. We
also modify the additive to suit special climate conditions.
