Biocement: A novel approach in the restoration of construction materials

Author: Enshasy, HE ; Dailin, DJ ; Malek, RA ; •Nordin, NZ ; Nordin, NZ ; Keat, HC ; Eyahmalay, J ; Ramchuran, Santosh O ; Ghong, JNC ; Ramda, VM ; Lalloo, Rajesh Date: Jun 2020 Concrete is the most commonly used construction material worldwide for the development of durable structures. Structural integrity and design of buildings have become increasingly important in construction engineering as well as assessment ... Read more
Conversion of calcium sulphide to calcium carbonate during the process of recovery of elemental sulphur from gypsum waste

Author: De Beer, Morris ; Maree, JP ; Liebenberg, L ; Doucet, FJ Date: Nov 2014 The production of elemental sulphur and calcium carbonate (CaCO(sub3)) from gypsum waste can be achieved by thermally reducing the waste into calcium sulphide (CaS), which is then subjected to a direct aqueous carbonation step for the generation ...

Mitigating health problems associated with AMD in South Africa

Author: Schachtschneider, K Date: Mar 2012 Acid mine drainage (AMD) is a serious threat to water quality in South Africa. Questions are being asked to South African government leaders as to what they are doing to mitigate the effects that South Africa’s mining industry is having on ... Read more
Recovery of calcium carbonate from steelmaking slag and utilization for acid mine drainage pre-treatment

Author: Mulopo, J ; Mashego, M ; Zvimba, JN Date: Jun 2012 The conversion of steelmaking slag (a waste product of the steelmaking process) to calcium carbonate (CaCO3) was tested using hydrochloric acid, ammonium hydroxide and carbon dioxide via a pH-swing process. Batch reactors were used to assess ... Read more
Studies on the mechanical and absorption properties of achatina fulica snail and eggshells reinforced composite materials

Author: Gbadeyan, OJ ; Adali, S ; Bright, G ; Sithole, Bishop B ; Awogbemi, O Date: May 2020 The present study focuses on the mechanical and absorption properties of composites reinforced by achatina fulica snail (S-shell) and eggshell particles (E-shell). Epoxy composites of snail and eggshell particles were prepared separately with ... Read more
Synthesis of high-purity precipitated calcium carbonate during the process of recovery of elemental sulphur from gypsum waste

Author: De Beer, Morris ; Doucet, FJ ; Maree, JP ; Liebenberg, L Date: Aug 2015 We recently showed that the production of elemental sulphur and calcium carbonate (CaCO3) from gypsum waste by thermally reducing the waste into calcium sulphide (CaS) followed by its direct aqueous carbonation yielded low-grade carbonate ...
