Products available for South Africa only: Regular tap-hole clays: CALDE™ TAP 010 FASX Reconstructive tap-hole clays: CALDE™ TAP 015 FASX Ladle castables: Q. Our product portfolio has also benefited from the acquisition of established refractory companies, whose products completed our existing range.The Calderys range was comprised of products that were sometimes very similar to one another.To ease the understanding of our new range, most of our products have been renamed using our international brands CALDE™, ALKON®- our dedicated range for Aluminium contact, and SILICA MIX.

Kynurenic acid is an endogenous neuroactive compound whose unbalancing is involved in the pathogenesis and progression of several neurological diseases.
In addition, these self-flowing or pumpable castables may be transported to high elevations (see SPRAYCAST).
the composition of a dry refractory material is such that it can be installed in powder form without addition of water or liquid chemical binders directly onto a heat source. Ramming materials have low moisture and are packed bulk in drums whereas plastics are softer and packed as slices in a box. For more details: SHOTCRETING - CALDE™ SPRAYCAST A new gunning installation technique for low cement castables (LCC) that allow to provide the same mechanical properties as corresponding LCC while using the same amount of mixing water as traditionally vibrated LCCs.
Kynurenic acid synthesis in the human brain is sustained by the catalytic activity of two kynurenine aminotransferases, h KAT I and h KAT II.
A wealth of pharmacological data highlight h KAT II as a sensible target for the treatment of neuropathological conditions characterized by a kynurenic acid excess, such as schizophrenia and cognitive impairment.
In the past most castables were installed by gunning or casting, the latter requiring internal or external vibration for the placement of low cement castables to fill in behind forms.
The ability of the low cement, self-flowing castables to move behind forms and around anchors in difficult to reach areas is a great advantage in installation.
In 2008, the range was rationalized and only the best performing products were retained.
Committing ourselves to innovation and continuous improvement, this product portfolio allowed us to focus on a more simplified and enhanced range.
Notably, given the critical role played by α7-n ACh R and NMDA receptors in the brain, abnormal KYNA disposition may contribute to the pathogenesis and progression of neurological or psychiatric diseases that are associated with impaired cholinergic and/or glutamatergic neurotransmission (6).
