No Cement Castables

a new family of sol-gel bonded castables

Cement

(2)



The new product line named COMPAC SOL is based on a completely

different bonding system, based on nano-particle silica.



This bonding system replaces the conventional cement as binder

What are Sol-Gel bonded castables?

36

2 RHI AG



This bonding system replaces the conventional cement as binder

and its complex system of (hydrated) calcium-aluminate-phases.



The binder is delivered separately from the mix.

(3)

 easy to dry, no specific pre-drying requirement.

 Fast and easy heating-up procedure.

 Reduced ambient temperature impact on final product properties.

 Reduced sensitivity to incorrect dosing of the mixing fluid.

Advantages

36

3 RHI AG

 Reduced sensitivity to incorrect dosing of the mixing fluid.

 Easily adjusted to the desired setting time.

 Higher refractoriness compared to equivalent cement-bonded products.

 Improved chemical resistance (e.g., alkali as well as sulphur) compared to equivalent cement-bonded products.

(4)

Sol-gel bonded castables:

 The setting and hardening of the concrete (jellying) is based on the formation of Si-O-Si - bonding

 NO chemically bonded water, no hydrate phases

Difference cement-/ sol-gel bonded castables

4 RHI AG

 NO chemically bonded water, no hydrate phases

 easy drying and heating up

 NO chemical additives necessary

in order to achieve a controlled and practice-oriented setting and hardening of LCC & ULCC

Disadvantages: separate binder,

Drying and Heat Up of Sol-products - Heat-up Process

The average pore size in Sol-mixes is significantly lower than for a LCC (lower risk of infiltration).

Homogeneous pore-structure and (size) distribution (better heat up properties).

36 7

In relation at low temperatures a higher pore-volume (better heat up), because you can use all the pores at very low temperatures. For cement bonded castables, a large amount of pores are created lately during the heat up. No increase of porosity at higher (>200°C) temperatures.

Safe and very fast heat up that can be finished completely even below 200°C!

As the castable was stored correctly it

was possible to keep the temperature

of the mix at about 10°C.

The castable was easy to pour into the

moulds and also easy to vibrate and

fields were very homogeneous without

formation of cavities.

Especially for the burner pipe the advantages of Sol castables are of particular interest, such as:

• No need for heating up

• Higher refractoriness compared

Comparison of a burner pipe from an Egyptian customer lined with high alumina standard low-cement castable from a competitor and with CARSIT SOL M10-6.

(22)

References 7: nose ring

Another Egyptian customer use the material for casting a 15t nose ring, which had previously less than two months life time. In this case one of the main reasons for choosing a sol-bonded material was, that the flexibility of the material is better than the more brittle behaviour of a conventional castable but still having a high strength. Furthermore nose ring areas cant be heated up correctly because their proximity to the main burner.

References 9: gunning

Gunning techniques (guniting or shotkasting) are popular installation methods for minimising turnaround times. RHI is proud to be the first in the market to offer its customers the advantages of sol products also for gunning installation. COMPAC / CARSIT SOL gunning materials can be installed using the common conventional or dense gunning equipment.

installation after one year

The only special equipment needed is a simple pump for adding the liquid binder DIVASIL at the gunning nozzle.

The first field trials using CARSIT SOL F10G-6 were conducted already in February and March 2011 at cooler sidewalls and roofs in cement plants in

Germany. As these trials showed very promising results in the last winter repair period 2011/2012 (fotos next page). More German cement customers ordered material for their stops.

All the applications so far have proved:



No need of pre-drying and easy heating up:

Although the castables have not been pre-dried and where heated up

36

35 RHI AG

Although the castables have not been pre-dried and where heated up

with the same heating up curve as applied to basic bricks, there was

no spalling or pre-damage of the castables.



Perfect workability and setting also under extreme winter conditions.
