Bentonite is commercially viable due to its superior plasticity and lubricity, high dry-bonding strength, high shear and compressive strength, low permeability, and low compressibility. Bentonite is valuable for binding foundry sand, drilling mud, pelletizing iron ore, and as a waterproofing and sealing agent in construction projects; it also ...
building structures, there is an urgent need to find low-cost natural pozzolans to replace the cement[3-6]. Natural pozzolans have many properties, such as high ultimate strength, low heat of hydration, low permeability, and high sulfate resistance, which make it a great benefit in mortar and concrete.[7, 8]. Bentonite, a natural
Low alkali cements produce lower pH (around 10-11) leachates and it is expected that this will slow bentonite reaction (or even stop it altogether) over the timespan of relevance to repository safety.
It was therefore decided to implement a focussed natural analogue study on bentonite/low alkali cement leachate reactions to provide indications of the probable long-term reaction products and reaction pathways to provide feedback on the existing short-term investigations noted above and to ascertain if any critical path research and ...
