"ABSTRAK
This project has an objective to reduce the use of cement for paste by replacing partial part of the concrete with limestone. This experiment focuses on the effect of the shear thickening behaviour to the behaviour of the paste and hence concrete. The idea of such a replacement is generated in order to reduce the effect of carbon footprint. In addition, the cost of cement paste production can be minimised as well since the percentage of cement in paste is reduced and replaced. Several pastes with various percentage of replacement were tested. Limestone as replacement has been proven to reduce the effect of shear thickening. The reduced effect of shear thickening is considered to be beneficial in construction industry.

ABSTRAK
Riset ini mempunyai tujuan untuk mengurangi penggunaan semen dalam pasta dengan mengganti beberapa bagian dari pasta dengan batu kapur. Eksperimen ini terfokus pada efek dari prilaku penebalan geser dengan prilaku pasta begitu juga beton. Ide pengganti tersebut dihasilkan dalam rangka mengurangu efek jejak karbon. Selain itu, biaya produksi pasta semen dapat diminimalkan karena persentase semen dalam pasta berkurang dan diganti. Beberapa pasta dengan persentase pengganti yang berbeda telah dites. Batu kapur sebagai material pengganti telah terbukti mengurangi efek dari penebalan geser. Berkurangnya penebalan gesel dinilai menguntungkan di dunia kontruksi."

"Semen merupakan salah satu material yang sangat penting dalam proyek konstruksi teknik sipil. Namun dalam proses pembuatannya, semen menghasilkan emisi karbondioksida. Berdasarkan literatur, penggunakan material yang memiliki sifat semen telah digunakan untuk mengurangi kebutuhan semen yang secara tidak langsung mengurangi produksi semen yang menghasilkan emisi karbondioksida. Geopolimer merupakan salah satu alternatif yang bisa digunakan dimana pasta semen dalam mortar dan beton konvensional digantikan oleh pasta geopolimer. Di dalam penulisan ini akan dibahas mengenai studi literatur mortar dan pasta geopolimer. Pengumpulan literatur, pengelompokan literatur dan pengambilan kesimpulan adalah metode yang digunakan dalam penulisan. Analisa yang dilakukan adalah berdasarkan pengelompokan akan hal-hal yang mempengaruhi mortar dan pasta geopolimer. Dari hasil studi literatur didapat bahwa bahwa geopolimer merupakan salah satu alternatif pengganti semen Portland dan jenis prekursor, faktor air prekursor, metode curing, dan aktivator adalah hal-hal yang berpengaruh pada geopolimer.

Cement is one of the most important material in civil engineering construction projects. However, in the process of manufacture, cement produces carbon dioxide emissions. The used of material that have properties of cement based on the literature review propose to reduce the need for cement, which indirectly reduce carbon dioxide emission produced by the cement industries. Geopolymer is one alternative that can be used where the cement paste in conventional mortar and concrete were replaced by geopolymer paste. In this paper will be discussed regarding the literature study geopolymer mortar and paste. Collecting literarure, grouping the literature and making conclutions is a mehtod of this writing. The analysis conducted is based on the grouping of things that affect geopolymer mortar and paste. The results of this literature study are geopolymer is one alternative to replace Portland cement and the type of precursors, water precursor ratio, curing method and activator are things that affect geopolymer."

Scott, Erik R.
"Familiar Strangers tells the story of a remarkably successful group of ethnic outsiders at the heart of Soviet empire and, in so doing, offers a new interpretation of Russian and Soviet history in the twentieth century. While past scholars have portrayed the Soviet Union as a Russian-led empire composed of separate national republics, Scott makes the case that it was actually an empire of diasporas, forged through the mixing of a diverse array of nationalities. Concealed behind external Soviet borders, internal diasporas from the Soviet republics migrated throughout the socialist empire, leaving their mark on its politics, culture, and economics. Among the Soviet Unions internal diasporas, the Georgians were arguably the most prominent group. The roles they played in the Soviet empires evolution illuminate the opportunities as well as the limitations of the Bolshevik Revolution for ethnic minorities. Looking at the rise and fall of the Soviet Union from a Georgian perspective, this book moves past the typical divide between colonizer and colonized that guides most scholarship on empire and argues for a new theory of diaspora, with implications far beyond the imperial borders of Russia and Eurasia."
