Nine IMD stations (Alipore, Krishnagar, Sagar Island, Midnapore, Berhampore, Bankura, Contai, Shantiniketan, Haldia), distributed randomly in alluvial, red-laterite and coastal regions of West Bengal, were selected for studying the temperature change. First five stations have database of 105 years, sixth, seventh and eighth stations have database of 45years and the ninth station has the databas...

This study investigates the influence of curing age and mix proportions on the compressive strength of volcanic ash (VA) blended cement laterized concrete. A total of 288 cubes of 100mm dimensions were cast and cured in water for 3, 7, 28, 56, 90 and 120 days of hydration with cement replacement by VA and sand replacement by laterite both ranging from 0 to 30% respectively while a control mix o...

The performance and kinetic of saprolitic laterite reduction using palm kernel shell charcoal anthracite were studied. coal represents the conventional high-grade carbon content matter, biomass-based reductant. experiment was conducted at a temperature ranging from 800oC 1000oC. XRD analysis applied to observe phase transformation. For study, two models, namely (1) Jander (2) Ginstling-Brounhst...

Limonitic nickel laterite always contains abundant high smelting components such as Al2O3 and MgO, which is extremely adverse to sintering. To weaken the negative effect of components, in this study, sinter pot tests limonitic were conducted for better sintering performance by optimization (MgO + Al2O3)/SiO2 mass ratio at same basicity. The relevant mechanism was revealed theoretical analysis m...

This paper presents a study on the thermal characterization of laterite used as building material. In Senegal, has been in construction semi-industrial scale since 1990s through projects aimed at promoting local materials that can contribute to energy efficiency buildings. The aim work is determine characteristics composite (laterite + peanut shell). results showed pure specimens have higher co...
