Conclusions
Dinas brick in the lining of soakingpits at 1400 – 1450‡ showed the same resistance as dinas brick, to the separating wall under the refractory layer the dinas concrete did not fuse and after 8 months of service was still suitable for further use.
Temperature measurements show that the surface of the brickwork below the refractory lining heats up to 1200‡. This excludes the possibility of using heat-resistant concrete with a portland cement base and a chamotte filler in the brickwork of the basic walls of pits.
Dinas concrete blocks can be used to replace dinas brick in the working lining of soaking pits and chamotte in the
