This paper sought to explore the possibility of getting good pavement material from marine clay stabilized with cement and lime. Various tests analyses were carried out examine effects lime on soil. These repeated at intervals. Firstly, by carrying natural disturbed soil, then intervals, addition admixture (cement lime) 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%. With an increase admixtures; plasticity...

In order to accurately obtain the mining activities of Roliai laterite nickel mine, based on remote sensing technology and object-oriented image analysis, methods multi-scale segmentation scale optimization optimal classification threshold selection were used extract nine activity elements from WorldView II images 2013 2020 respectively. According extraction results, dynamic changes each elemen...

This paper presents the results of experimental evaluation curing conditions on microstructure and performance geopolymer binders developed from iron-rich laterite soils. Two calcined laterites namely LB600 LY600 were used as solid precursors in preparation binders. The samples cured at 20, 60 80 °C. FTIR, XRD, EDS DTA/TG to evaluate microstructural properties prepared products. binder was eval...
