SECAR® 70V - SECAR®, solutions for refractories

Product Data Sheet
SECAR® 70V
Reference FC-S70V-RE-GB-KFR-012012
1 Description
2 Specifications
SECAR® 70V is a hydraulic cement with alumina
content approx. 70%. It consists of calcium aluminate
phases making it suitable for refractory applications.
Although SECAR® 70V can be used for making all
types of refractory castables, it is designed and
therefore, more suitable for conventional castable
applications.
SECAR® 70V is manufactured by a well controlled
sintering process, which provides the product with
high level of consistency in terms of its chemical,
physical properties and final performance.
SECAR® 70V is designed to give optimized
application performance of a range of different
conventional castable types.
SECAR® 70V shows versatility in terms of installation
techniques of conventional castables. It develops
good flow even at high ambient temperature, making
it compatible to Indian climate. Good flow with low
water demand makes SECAR® 70V-containing
conventional castables suitable for vibration casting
application.
Moreover, SECAR® 70V-containing patching
castables are found to develop an appropriate
rheology which helps sticking to the wall. For all types
of installations, SECAR® 70V-containing conventional
castables show long working time, yet fast hardening
leading to a quicker demoulding and rapid return to
service.
SECAR® 70V can be used for any conventional
castable application, including those involving high
temperature and requiring high purity cement.
SECAR® 70V is produced and controlled within a
quality management system that is certified according
to ISO 9001.
The specification limits indicated are determined with
an acceptable quality level (AQL) of 2.5% as defined
in the sampling standard ISO 3951.
The usual range represents typical values of our
production. The values presented are provisional
values which will be validated over the course of 12
months production.

Workability
The workability of SECAR® 70V has been determined
by measuring the flow properties using the ASTM
C230 flow table. The test is carried out using a
standard siliceous sand mortar.
Usual range
Specification
Flow after 0 min 90-130
Flow after 30 min 70-120 > 50
w Composition and preparation of the sand mortar is determined
by standard EN 196-1: cement 500 g, sand 1350 g, water 200
g (W/C = 0.40).
w Tested at 20°C after 30 minutes with 25 shocks in ASTM cone
mould, d1 (diameter of base) = 100 mm, d2= diameter after 25
shocks, Flow (%) = ((d2-d1)/d1)x100.

Storage and shelf life
w Composition and preparation of the sand mortar is determined
by standard EN 196-1: cement 500g, sand 1350g, water 200g
(W/C = 0.4).
w Setting time measurement according to NF P15-431: Vicat
apparatus standard EN 196-3 but using a 1000 g test weight;
temperature 30°C; samples immersed in water or cured at > 90%
relative humidity.
w Final setting time measured in accordance with NF P 15-330:
the Vicat needle no longer penetrates the mortar.
In common with all hydraulic binders, SECAR® 70V
must be stored in shrink wrapped condition on pallet,
as supplied, in dry conditions under a covered storage
area. SECAR® 70V when stored correctly will retain
its properties for at least 6 months.
