In this paper, the effect of additives such as deflocculants and dispersants; on the properties of alumina low-cement selfflowing castables has been investigated. The flow and setting behavior, major physical and mechanical properties of these castables have been tested. Also, the microstructures of these castables have been evaluated. The results show that(More)
Recovery of spores and crystals from the fermentation broth of Bacillus thuringiensis (Bt) was studied using the membrane separation technology. Four types of polymeric membranes, with different characteristics, in the range of microfiltration (MF) and ultrafiltration (UF) were used for evaluating their permeate flux and spore–crystal recovery capacity.(More)
