Insulating lightweight refractory concrete – ORBET IZO 0.6

Product Description

LIGHT insulating refractory concretes
are mixtures of refractory and fireproof raw materials and refractory cement, and are used for the production of insulating and working linings of industrial furnaces.
They are delivered in a dry state, and are stored in closed areas protected from moisture.

Before use, it is recommended to mix in a dry state for homogenization.

Lightweight concrete is prepared for installation by mixing in clean mixers or manually, with the addition of an appropriate amount of water,
depending on the type of aggregate and grain size.
Installation is carried out by casting into previously placed templates made of smooth boards, coated with a protective coating.
Lightweight refractory concrete sets after 15-20 minutes, and hardens in 24-48 hours.
The hardening time is shorter in warm conditions, and longer in cold conditions.

It is recommended to install lightweight concrete at a temperature of 5-30 C.

The process of hydraulic hardening is accompanied by the release of heat, so it is necessary to moisten the concrete with water during the first 24 hours. The approximate drying and initial heating regime is as follows:

• During the hardening period, which lasts 24 hours, if possible, maintain the concrete by occasional wetting.
• Air drying lasts 24 hours, then it is heated to 150 ( 0C ) and held for 12 hours. The rate of temperature increase from 150 ( 0C ) to 650 ( 0C ) is 15 ( 0C/h ). At 650 ( 0C ) keep the temperature constant for 10 hours, and then heat to operating temperature at a rate of 50 ( 0C /h ).
• The permitted temperature during installation is +5 to +30 (0C), and if it is lower, add antifreeze additives.
