Influence of Utilizing Prosopis Juliflora Ash as Cement on Mechanical Properties of Cement Mortar and Concrete

by

Karthikeyan Ganesan et al. View all

Ecology, environmental change and management

The infrastructure of the country heavily depends on the construction material concrete. The primary ingredient in conventional concrete is cement, fly ash, or another cementitious substance. The need to explore alternative sources is driven by the challenges posed by global environmental warming...

Diatom records in sediments for eutrophication process of Lake Xian'nv, China since the mid-20th century

by

Yong Ji et al. View all

Ecological effects of Environmental change

To well understand the eutrophication process for inland lakes where more lands had been used for agriculture and industry without adequate environmental protections, 9 surface sediments and 1 core sediment in Lake Xian’nv which was located in the middle of Jiangxi Province were chosen. Combined...

Spatiotemporal variability of heavy metals concentration in an industrialized estuarine-bay ecosystem in Northern Persian Gulf

by

Mahsa HakimiAbed et al. View all

Ecological effects of Environmental change

This study aimed to evaluate the pollution level of Ni, Pb, Cd, V, and Hg in the sediments of Musa Estuary and its four main tributaries namely Majidieh, Zangi, Semaili, and Merimos (collectively known as Mahshahr estuaries) in summer and winter 2019 using sediment quality indices. In each tributary...

Effect of coconut shell ash as an additive on the properties of green concrete

by

S. Shanmuga Priya et al. View all

Solid Waste Management

Concrete is the broadly adopted composite material in the construction arena. The growing need for cost-effective housing is resulting in the depletion of environmental resources such as river sand and gravel, which are essential components in the manufacture of concrete. However, the manufacturing...

Anaerobic Digestion of Corn Stover Pretreated with Sulfuric Acid in Different Soaking Durations

by

Lukhi Mulia Shitophyta et al. View all

Biowaste

The biogas production of pretreated corn stover has been determined in different soaking durations. Batch anaerobic digestion applies three different soaking durations in sulfuric acid pretreatment under room temperature. The study aimed to probe the effect of soaking durations during sulfuric acid...
