The effect of wollastonite powder with pozzolan micro ...

Wollastonite (CaSiO3) is an important mineral that is widely used in ceramics and polymer industries. Defect energetics, diffusion of Ca ions and a solution of dopants are studied using atomistic-scale simulation based on the classical pair potentials. The energetically favourable defect process is calculated to be the Ca-Si anti-site defect cluster in which both Ca and Si swap their atomic ...

Consequently, the use of wollastonite powder to the manufacturing of conventional structural concrete containing recycled ceramic aggregates, in addition to improving some of the properties of concrete are environmentally friendly solutions, providing natural recycling of materials.

US3576657A - Method of treating wollastonite - Google Patents

Jun 20, 2019· In this work, the possibility of applying silica gel waste for the production of wollastonite via both single- and two-step methods was investigated. For the synthesis of wollastonite, two initial mixtures with CaO/SiO2 molar ratio of 0.75 and 1.0 were prepared. The synthesis was done by single-step and two-step methods: one-step synthesis was carried out in 800–950 °C temperature range in ...

Effects of wollastonite substitution were investigated relative to the mechanical, physical, and microstructural properties of a wood fiber-cement composite. Wollastonite content of 0%, 3%, 6%, and 9% and lignocellulosic material (kraft fibers) content of 10%, 20%, and 30% were used based on the dry weight of cement.

Phosphorus removal by wollastonite: A constructed wetland ...

Recycling composites is difficult since they typically contain two or more components (filler, fiber, resin, etc.). Recycling thermoset composites is a particular challenge since, once the thermoset matrix molecules are cross- linked, the resulting material can no longer be remelted or remoulded [4]. Further, the most common thermoset-
