Thesis (DTh (Practical Theology and Missiology))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This study is descriptive research and a practical theological study of the schisms in the Reformed Church in Zambia (RCZ) that took place between 1996 and 2001 and led to the formation of the Christian Reformed Church (CRC) and the Bible Gospel Church in Africa (BIGOCA). It aims to analyse the historical, global and local contexts as regards these schisms in the RCZ. The research questions are: What led to these splits, how did they happen and how can they be prevented? No measures have been put in place to educate or guard against further schisms. The goal of this study is to propose informed precautionary measures to the RCZ to prevent a recurrence of schisms in future. Chapter 2 describes the faith tradition of the RCZ. Various historical perspectives from the colonial period to those of the current Zambia are discussed in order to provide an understanding of this denomination's identity. It also tries to determine whether her political and missionary legacy has influenced the RCZ's leadership style and structures. Chapter 3 is an attempt to understand the contextual influences that globalization have brought about. The correlation between the global and religious trends affords a perspective on the "why" question of the schisms. Various global and local developments are the major focus of this chapter. It also discusses three levels of influence: macro (the global society), meso (the Zambian society), and micro (faith communities at congregation level). In Africa, the Pentecostal/charismatic oriented Christian prosperity movements have caused one of its endemic problems, i.e. the tension. Within the context of the RCZ tradition and faith practices, the Pentecostal/charismatic tendencies have challenged the long inherited autocratic church leadership styles. Pentecostal/charismatic prosperity movements flew in the faces of the denominationally organized churches with their Western origin, such as the RCZ. Subsequently, Pentecostal/charismatic movements have caused intense conflict in the church between the pro-conservatives and pro-Pentecostals. The police even had to close certain RCZ congregations because of skirmishes. At this stage of the study, a hypothesis became clear: The one-party state, with its autocratic presidential powers, continued the missionary legacy of autocratic rule in the independence and post-independence era, which had a direct impact on church leadership. Rutoro (2007) came to the same conclusion in his research on leadership in the Reformed Church in Zimbabwe. Chapter 4 is descriptive and provides a survey of what the documental sources of the RCZ and the printed media reveal about the schisms. The Synod's recommendations and resolutions from 1996 to 2001 give a clear picture of what occurred, as well as the intensity of the conflict. This chapter also reveals how the RCZ interpreted and handled the situation. Chapter 5 discusses the empirical data-gathering methods and the pilot study. Chapter 6 deals with the interpretation of the gathered data and compares it with the findings of Chapter 4. It is an exercise in triangulation - done after the first five chapters were written and affirmed what Chapter 4 concluded but, because of the narrative part of many of the answers supplied in the open-ended questionnaire, more was learned from it than was expected. From this study, it is clear that the church leadership should focus on understanding the *winds of change* in order to discern the way forward and adapt to leadership styles and challenges. Making theologically informed decisions are an absolute priority for the RCZ. This study recommends that church leadership, at least all the ministers, should be trained in conflict resolution and management and should stay abreast of God's missional praxis in this fast and ever-changing world. / AFRIKAANSE OPSOMMING: Hierdie studie is beskrywend van aard en is 'n prakties-teologiese evaluering van die skeurings in die Reformed Church in Zambia (RCZ) wat tussen 1996 en 2001 plaasgevind het, en wat tot die stigting van die Christian Reformed Church (CRC) en die Bible Gospel Church in Africa (BIGOCA) gelei het. Dit beoog om die historiese, globale en plaaslike kontekste met betrekking tot hierdie skeurings in die RCZ te ontleed. Die navorsingsvrae is: Wat het tot hierdie skeurings gelei, hoe het hulle gebeur en hoe kan hulle voorkom word? Geen maatreëls is getref vir opleiding of waaksaamheid teen verdere skeurings nie. Die doel van hierdie studie is om ingeligte voorkomende maatreëls aan die RCZ voor te stel om 'n toekomstige herhaling van skeurings te verhoed. Hoofstuk 2 beskryf die geloofstradisie van die RCA. Vir 'n begrip van hierdie denominasie se identiteit word verskeie historiese perspektiewe vanaf die koloniale tydperk tot dié van die huidige Zambia bespreek. Daar word ook gepoog om vas te stel of die RCA se politieke en missionêre nalatenskap die RCZ se leierskapstyl en strukture beïnvloed het. In Hoofstuk 3 word gepoog om die kontekstuele invloede wat globalisasie mee-gebring het, te verstaan. Die korrelasie tussen die globale en geloofstendensies verleen 'n perspektief op die skeurings se "waarom" vraag. Verskeie globale en plaaslike ontwikkelinge is die hoof fokus van hierdie hoofstuk. Drie vlakke van invloed: makro (die globale samelewing), meso (die Zambiese samelewing), en mikro (die geloofsgemeenskap op gemeentevlak) word ook bespreek. In Afrika het die Pinkster-/charismaties-georiënteerde Christelike welvaartsbewegings een van sy endemiese probleme veroorsaak, naamlik spanning. Binne die konteks van die RCZ tradisie en geloofspraktyke, het die Pinkster/ charismatiese tendensie die lank-oorgelewerde outokratiese kerkleierskapstyle uitgedaag. Die Pinkster/-charismatiese welvaartsbewegings het gestaan teenoor die denominasioneel georganiseerde kerke met 'n Westerse oorsprong, soos die RCZ. Daarna het die Pinkster/charismatiese bewegings intense konflik in die Kerk tussen die pro-konserwatiewes en die pro-Pinkstergesindes veroorsaak. As gevolg van skermutselings moes die polisie selfs sekere RCZ gemeentes sluit. Op dié stadium van die studie het 'n hipotese duidelik geword. Die eenparty staat, met sy outokratiese presidensiële mag, het die missionêre nalatenskap van outokratiese beheer in die onafhanklike en post-onafhanklike era voortgesit, wat ‘n direkte impak op kerkleierskap gehad het. Rutoro (2007) kom tot dieselfde slotsom in sy navorsing op leierskap in die Reformed Church in Zimbabwe. Hoofstuk 4 is beskrywend van aard en bevat 'n oorsig van wat die dokumentêre bronne van die RCZ en die gedrukte media oor die skeurings openbaar. Die Sinode se aanbevelings en besluite van 1996 tot 2001 verskaf 'n duidelike prent van die gebeure, sowel as die intensiteit van die situasie. Hoofstuk 5 bespreek die metode van empiriese dataversameling en die loodsstudie. Hoofstuk 6 handel oor die interpretasie van die versamelde data en vergelyk dit met die bevindings van Hoofstuk 4. Dit is 'n oefening in triangulering – wat gedoen is na die skryf van die eerste vyf hoofstukke. Dit bevestig Hoofstuk 4 se afleidings maar, vanweë die narratiewe deel van baie van die antwoorde wat in die vraelys verskaf is, is meer as wat verwag is hiervan geleer. Deur hierdie studie word dit duidelik dat kerkleierskap op die verstaan van die *winde van verandering* gefokus moet wees om die weg vorentoe te bepaal en die leierskapstyle en uitdagings aan te pas. Om teologies-ingeligte besluite te neem is 'n absolute prioriteit vir die RCZ. Hierdie studie beveel aan dat kerkleierskap, of minstens al die predikante, in konflik-oplossing en –bestuur opgelei moet word, en tred moet hou met God se missionêre praksis in hierdie snelle en steeds veranderende wêreld.

Denna studie utforskar användningen av Re-Con Zero ballast (RCZ-ballast), ett material framställt från återvunnen betong och en tvåkomponents pulverprodukt, som ett alternativ till traditionellt jungfruligt ballastmaterial i betongproduktion. Studiens huvudsakliga syfte är att bidra till en mer hållbar och cirkulär betongindustri, där restbetong inte blir ett avfallsproblem utan en värdefull resurs. Studien vill fylla en kunskapslucka om hur RCZ-ballast påverkar betongens färska samt hårdnade egenskaper. Studien undersöker om RCZ-ballast kan matcha prestandan hos traditionellt ballastmaterial med avseende på viktiga betongegenskaper som densitet, vattenabsorption, samt mekaniska egenskaper som sättmått, lufthalt och tryckhållfasthet. Experimentella metoder inkluderade tester för att jämföra mellan betongblandningar med traditionellt ballast och den som innehåller en del RCZ-ballast. Dessa tester omfattade densitet och vattenabsorption på RCZ-ballast, dessutom mätningar av sättmått och lufthalt vid olika tider (0, 30 och 60 minuter) samt tryckhållfasthet vid olika härdningstider (1, 7 och 28 dagar) för samtliga blandningar.  Resultaten från dessa tester visade att betong framställd med RCZ-ballast generellt hade högre vattenabsorption och lägre densitet jämfört med traditionella blandningar. Trots dessa material betingade skillnader uppnådde betongen med RCZ-ballast likartade tryckhållfasthetsvärden inom ramen för ett normalfördelat material vid alla testade tidpunkter. Detta visar att RCZ-ballast anses vara lämplig med avseende på tryckhållfasthet. Slutsatserna från studien understryker att RCZ-ballast, framställt från restbetong, är ett fullt fungerande alternativ till jungfruligt bergmaterial i betong, med god tryckhållfasthet. Det finns dock tydliga skillnader i sättmått, där betongens beteende varierar beroende på om den blandas med nyproducerad eller mättad RCZ-ballast. Studien avslöjar även att både nyproducerad och mättad RCZ-ballast påverkar betongens lufthalt på olika sätt jämfört med betong som är tillverkad med jungfruligt ballastmaterial. / This study explores the use of Re-Con Zero aggregates (RCZ-aggregates), a material made from recycled concrete and a two-component powder product, as an alternative to traditional virgin aggregates material in concrete production. The primary purpose of the study is to contribute to a more sustainable and circular concrete industry, where surplus or excess  concrete does not become a waste problem but a valuable resource. The study aims to fill a knowledge gap regarding how RCZ-aggregates impacts the fresh and hardened properties of concrete. The study investigates whether RCZ-​​aggregates can match the performance of traditional aggregates materials with respect to key concrete properties such as density, water absorption, and other mechanical properties like slump, air content, and compressive strength. Experimental methods included tests to compare between concrete mixes with traditional aggregates and those containing RCZ-aggregates. These tests measured the density and water absorption of RCZ-aggregates, as well as slump and air content at different times (0, 30, and 60 minutes) and compressive strength at various curing times (1, 7, and 28 days) for all mixes. The results from these tests showed that concrete made with RCZ-aggregates generally had higher water absorption and lower density compared to traditional mixes. Despite these material-induced differences, the concrete with RCZ-aggregates achieved compressive strength values that were similarly within the range of a normally distributed material at all tested times. This demonstrates that RCZ-aggregates is considered suitable in terms of compressive strength. The conclusions from the study underscore that RCZ-aggregates , made from residual concrete, is a fully functioning alternative to virgin aggregates material in concrete, with good compressive strength. However, there are clear differences in slump, where the behavior of the concrete varies depending on whether it is mixed with newly produced or saturated RCZ-aggregates. The study also reveals that both newly produced and saturated RCZ-aggregates affect the air content of concrete differently compared to concrete made with virgin aggregates material.
