description PURPOSE:To enhance both casting workability and resistance to explosion at a time of preheating and drying by blending an oxycarboxylic acid and/or its carboxylate with a composition consisting of refractory aggregate, refractory superfine powder, a dispersant and a curing agent. CONSTITUTION:(D) 0.3 to 3wt.% oxycarboxylic acid (e.g. glycolic acid) and/or its carboxylate (e.g. sodium glycollate) is blended with a composition consisting of (A) acidic, neutral or basic refractory aggregate (e.g. electromelted alumina aggregate) regulated in particle size in accordance with necessity, (B) 5 to 15wt.% refractory superfine powder (e.g. alumina ultrafine powder) having
