Sodium Lignosulfonate Powder Used as Concrete Water

The addition of lignosulfonate powder can reduce water consumption by 1015 increase strength by 1020 in 28 days and increase strength by about 10 in one year Saving cement consumption When the strength and slump of the concrete are similar the cement can be saved by about 10 and the use of 1 ton of water reducing agent can save 30

Refractory Bricks Fire Bricks Types Of Refractory Bricks

2 Mostly normal refractory brick created of natural fire clay is as good as acid brick but if additional acid resistance is required then an additional amount of silica is added to on fire clay which may range up to 97 of its composition For binding bases 1 to 2 lime may be added onAcid bricks are burnt at large temperatures for lengthy periods 2 Ordinary Refractory Brick

Spinel Refractory Material DXD

Spinel Spinel refers to a class of minerals with the same structure The chemical formula can be expressed as AO R2O3 where A represents a divalent element ion which can be Mg2 Fe2 etc R is a trivalent element which can be Al3 Fe3 Cr3 and so on Most of them exist in the form of isomorphous solid solution All spinel forms a solid solution by expanding the

DEVELOPMENT OF ALUMINUM DROSSBASED

201216 Degassing has been used but this can only reduce 5 of dross and there is a cost associated with this step 2 The other possibility is to convert dross recovery into a nonsalt processing step Recycling of aluminum dross without salt fluxes and usingplasma torch es has been developedin France however it is more costeffective
