Influence of scoria and pumice on key performance indicators of Portland cement concrete
(Elsevier Ltd, 2019-02-10)Cement industries have a huge CO2 signature that can be reduced in an effort to mitigate climate change via precise cement substitution with supplementary cementing materials (SCMs). The substituting materials and their ... -
The influence of stereochemistry of the active compounds on fluoride adsorption efficiency of the plant biomass
(Science Publishing Group, 2014-08-20)Several studies have reported various defluoridation capabilities of plant biomasses. The resultant variations in fluoride removal capacities are associated with the presence of different types of active functional groups ... -
Informing versus generating a discussion: Comparing two approaches to encouraging mitigation of soil erosion among Maasai pastoralists
(Elsevier, 2022-10-21)Soil erosion is a critical problem for pastoralist societies that rely on healthy grazing land for their livelihoods. Previous research suggests that unsustainable land management practice is one of the factors exacerbating ... -
Inhibition of aluminium corrosion using carica papaya extracts in acidic media (sulphuric acid and phosphoric acid)
(NM-AIST, 2017-12)Corrosion inhibition of aluminium using Carica papaya leaves extracts in 1M H2SO4 and IM H3PO4 was investigated under different temperatures (30, 40 and 500C) and concentrations (from 20-100 v/v %). The inhibitor was found ... -
Innovations and Sustainability: The Case of Improved Biomass Stoves' Adoption and Use in Tanzania
(Lund, Sweden – Spring, 2009)The adoption and continued use of improved stoves in the developing countries is of social, economic and environmental concern. In most developing countries, biomass-based energy accounts for more than 90% of all household ... -
