The following paper presents the results of research on cement composites with expanded graphite as resistance heating elements. Samples of cement mortar were prepared with expanded graphite obtained from intercalated graphite by means of rapid heating at 1000℃. Monotonic and cyclic self-heating tests of cement composites with differing contents of expanded graphite were conducted. In the monotonic self-heating test, the electrical current and the surface temperature of the cement composites with expanded graphite were measured at temperatures 23℃ and –10℃ in order to evaluate their capacity to generate heat. The maximum temperature of composites, the time required to raise the temperature by 10℃, and the power density were determined. Five cycles were applied in the cyclic self-heating test to investigate heat-dependent mechanical properties. The results of the research revealed that cement composites with expanded graphite exhibited promising properties for application as resistance heating elements.

The goal of this article is to examine the introduction of plantations into East Sumatra (Indonesia) in the late nineteenth and early twentieth century. Attention is given to the five most important plantation crops, namely tobacco, rubber, oil palm, tea, and fiber. The article analyzes the economic and social transformation of the region as a consequence of the rapid expansion of plantations. Within a short period of time, East Sumatra emerged to become one of the most dynamic economic regions of Southeast Asia. The development of the region and the needs of a source of protection for Dutch planters in face of fierce competition from other Western companies and local resistance encouraged the Dutch colonial government to establish effective authority in East Sumatra.
