PROMACAST

PROPERTIES & ADVANTAGES

  • Compression-proof
  • High temperature resistant
  • Lightweight concretes 
  • For mechanically low-stressed areas up to 1370 °C

Refractory concrete

PROMACAST® is a well-balanced range of various types of refractory concrete for monolithic refractory linings. These products consist of highly refractory raw materials and aluminous cements. 

PROMACAST® lightweight refractory concretes are compression-proof and high temperature resistant, lightweight concretes for mechanically low-stressed areas up to 1380 °C, e.g. for burner benches, side walls and rear lining.

Working & processing
< #Back#
  1. PROMACAST compounds are delivered dry in bags. The mixture may demix during transport. We therefore recommend that the complete contents of the bag are put into the mixer. If only parts of the contents are used, mix the dry contents of the bag thoroughly beforehand.
  2. Use only clean tap water for mixing. Acidic water, soft water or water containing sulphate reduces strength and leads to structural faults.
  3. The specific quantity of water required for mixing is a standard value. Mixing should not take less than one minute and not exceed four minutes.
  4. The following on-site test will help you to determine whether the right consistency has been achieved: Make a ball the size of a snowball from the mixed compound, throw it approx. 30 cm in the air and catch it. If it retains its shape, the consistency is right. If it crumbles, the compound is too dry. If it falls through the gaps between your fingers, it is too wet.
  5. PROMACAST® products should be compressed immediately after mixing, using conventional tools. If setting has already begun, do not recompress.
  6. PROMACAST® must retain some of the mixing water while it is hardening. It is therefore necessary to protect it from drying out for at least 24 hours.
  7. The setting times change at temperatures below 5 °C. Make sure that the temperature of the prepared concrete is raised to at least 5 °C. Never use frozen material.
  8. For heating up the following rules should be observed: Setting period: 3 days; keep at 100 °C for 24h; keep at 200 °C for 48h; from 200 -  600 °C approx. 20 K/h; from 600 °C until the final temperature 30 K/h.
