Product DescriptionBending agent for concreteRA-KPerformance and
use:RA-K bending agent is a new type of concrete admixture
developed by our company for concrete with bending and tensile
(bending) strength requirements. It is mainly used in concrete
structures or components, such as pavement concrete, bridge
concrete and precast railway sleeper. Its main characteristics are
that it can significantly improve the bending strength of concrete,
improve brittleness, save cement, reduce maintenance costs, reduce
costs, open traffic in advance, and extend the service life of
cement concrete pavement.Scope of application:This product is
mainly used in road concrete, bridge concrete and precast railway
sleeper requiring flexural tensile (flexural) strength.Main
performance:1, in the case of constant slump of concrete, using the
recommended amount of this product, the water reduction rate can
reach 10 ~ 25%.2, this product uses reactive polymer copolymer as
slump retention component, its slump retention ability is strong,
workability is good, is conducive to centralized mixing, long
distance transportation.3. This product can improve the flexural
tensile strength (flexural strength) of cement concrete pavement.
Under normal circumstances, the flexural tensile strength (flexural
strength) of 28d cement concrete pavement can be increased by 15 ~
20%.4, this product can significantly improve the early strength
bending strength of concrete. 7d flexural strength increased by
more than 20%, 28d flexural strength increased by more than 15%, 7d
compressive strength increased by more than 25%, 28d compressive
strength increased by more than 20%.5. This product can increase
the folding ratio of concrete by more than 20%, improve the
brittleness of concrete, reduce the generation of broken plates and
cracks, and extend the service life of pavement.6. When the product
is mixed with the benchmark concrete to maintain the same slump and
strength, the cement can be saved by 10-25%.7, this product is
non-toxic, odorless, non-burning, no corrosion of steel bars.Usage
and precautions:1. Common dosage: The dosage range is 1.0% ~ 4.0%
of the amount of cementing material. Use in strict accordance with
the recommended dosage.2. Mixing method: When used, it should be
directly added to the mixer with cement to extend the mixing time
by 30 to 60 seconds.3, in order to ensure the best use results, it
is recommended that users use this product, according to the type
of cement, label and specific conditions of the project before the
use of this product to carry out the necessary concrete
test. Packaging & ShippingPacking specification:1.
The powder is packed in lined plastic woven bag with a net weight
of 25±1kg/ bag. The liquid agent is packed in 200±1kg iron drum or
1000kg plastic drum.2, Store in a dry place, pay attention to
moisture, sun protection.3, the warranty period is one year, the
extended product must pass the concrete test before it can be
used.Application displayEnvironmentCertifications FAQQ: Are
