One-part blast furnace slag mortars activated with almond-shell biomass ash: A new 100% waste-based material
(2020-08-01)
The use of almond-shell biomass ash (ABA) as an alkali source in one-part blast furnace slag (BFS) mortars activation was investigated for the first time. The chemical composition of ABA revealed high alkalinity ash to be ...
The role of dissolved rice husk ash in the development of binary blast furnace slag-sewage sludge ash alkali-activated mortars
(2022-07-15)
This study evaluated the compressive strength performance and microstructure of binary blast furnace slag-sewage sludge ash (BFS-SSA) alkali-activated mortars, in which rice husk ash (RHA) was dissolved in NaOH solution ...
Lanthanum-lithium-sodium double chromates as ionic conductors
(1997-03-20)
Lanthanum-lithium-sodium double chromates Li1-xNaxLa(CrO4)2 were prepared and analysed by means of admittance spectroscopy. Their a.c. conductivity parameters are correlated with structural details of high and low temperature ...
Dose-dependent in vitro inhibition of rabbit corneal matrix metalloproteinases by an extract of Pothomorphe umbellata after alkali injury
(Associação Brasileira de Divulgação Científica, 2007-08-01)
The in vitro ability of Pothomorphe umbellata ethanolic crude extract to inhibit matrix metalloproteinase (MMP) in normal cornea and in cornea after alkali injury was demonstrated. Corneas of albino rabbits were injured ...
