The Albertine Rift, which is part of the East African Rift, is a region prone to repetitive slope instability due to its intense rainfall, high weathering rate, and consistent seismic activities. Although this has led to several publications about landslides in the past. Unfortunately, not many attempts at gathering systematic data on landslide research in the western Albertine rift have been made so far. This study analyses the research carried out in landslides in Albertine rift during 2003-2019 on several parameters including: the title, authors, institutions, publication year, keywords, the names of journals publishing the articles, and language. The majority of papers were written in French (62%). Geo-Eco-Trop journal has published the greatest number of papers (46%). The majority of authors (67%) produced only one paper. Moreover, Moeyersons had the highest co-authorship connections ( 15), followed by Dille, Trefois, and Nobil with 14, 10, and 7 connections respectively. 13 institutions from 6 countries contributing to the researches. The most producing institutions were Royal Museum for Central Africa, followed by the "Université Officielle de Bukavu".

Cement-based grout has been used for ground improvement. Owing to environmental issues related to cement, its usage should be reduced. In this study, an inorganic binder is introduced to reduce the use of cement in grout. To evaluate the transient electrical and mechanical properties of the sand–cement admixture samples improved with the addition of inorganic binders, two non-destructive testing methods, the electrical resistivity and free–free resonant column tests, were adopted in addition to the unconfined compressive strength (UCS) test. Experimental tests were performed considering four different mixing ratios and three different cement contents, depending on the curing time. The results show that the mixing ratio and curing time have considerable effects on the electrical and mechanical properties of the mixture. The UCS decreases as the cement content decreases. However, sufficient UCS is expected to be obtained when the inorganic binder content is increased in the mixture. From the results, it is found that geotechnical properties of the mixture can be estimated in the field with proper non-destructive testing methods. It is expected that the data and trends proposed in this study can be used as a reference in predicting grouting quality in the field.
