The particle growth of silica below the isoelectric point plays a key role in oil well cements, production of silica gels and production of nanosilica by dissolving silicates. In this article, we study the particle growth of silica below the isoelectric point using olivine, a silicate mineral, and sodium silicate solutions as silica sources in acid, where the particle size, soluble silica conce...

Sillimanite is a very important raw material for the manufacture of refractory bricks used in iron and steel, cement and glass industries. In some coastal stretches of south India, the beach sand is contaminated with shell. After recovering heavy minerals like ilmenite, rutile, zircon and garnet by various physical separation techniques, the final sand containing sillimanite, quartz and shell i...

It is the key to concrete repair and strengthening construction that base has a certain quality strength. Based on mechanism of sodium silicate, silicate was modified develop kind compound liquid. Through contrast test results impregnation. The strength C5 before after increased by 42.5%, while C10 21.4%, C15 10%.

The construction of the future is moving in direction environmentally friendly materials and use various types industrial byproducts wastes. blast furnace slag (BFS) for production concrete one those alternatives. In this study, pastes concretes based on high-MgO BFS were alkali activated with 10% by weight sodium carbonate, silicate, a combination both. Heat treatment laboratory curing applied...

this study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% pb, 1.91% zn taken from changarzeh mine, south natanz, iran. the effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, ph and solid content were investigated in relation t...
