Author:Netterberg, F; Paige-Green, PDate:Apr 1984The problem of deterioration of lime, lime-slag and cement stabilized pavement layers during curing, before sealing and in service is partly ascribed to carbonation of the stabilizer during curing and subsequent exposure to the atmosphere ...Read more
Author:Mokoena, Refiloe; Mgangira, Martin BDate:Jul 2017Concrete block paving for roads has been proposed as part of a concept on sustainable infrastructure. In an effort to respond to sustainability and environmental awareness, the use of industrial by-products has been employed in the mix design ...Read more
Author:Steyn, WJvdM; Sadzik, E; Semmelink, CJDate:Oct 2001The purpose of this paper is to provide information regarding a conceptual performance model for Deep in Situ Recycled (DISR) pavements where both cement and either foamed bitumen or bitumen emulsion have been added to the mix. CSIR Transportek ...Read more
Author:Van Wyk, Llewellyn VDate:Nov 2010Construction is responsible for 50 per cent of all resources consumed in the world making it one of the least sustainable global industries. Although it is difficult to quantify, largely due to the highly variable amount of waste generated ...Read more
Author:Van Wyk, Llewellyn VDate:Aug 2010The building envelope plays a significant role in the performance of a building, especially with regard to the green building components. This chapter will focus on the external building envelope only, i.e., sub-structure, super structure, ...Read more
Author:Botha, PB; Semmelink, CJ; Raubenheimer, JDate:Oct 2005Stabilized layers are used extensively in South-Africa in the construction of roads. The layers are usually stabilized with hydrated road lime, cement, slag, fly-ash, bitumen emulsion, foamed asphalt or a combination of several of these agents. ...Read more
Author:Paige-Green, PDate:Nov 2009During the early 1980s a number of problems related to the loss of stabilization and disintegration of stabilized layers in roads (lime and cement) were reported in South Africa. This led to many comprehensive investigations and it was shown ...Read more
Author:Paige-Green, P; Ware, CDate:Jul 2006In situ recycling as a pavement rehabilitation option in South Africa is becoming increasingly important. Use has been made of both bitumen (emulsion and foamed) and traditional chemical stabilizers (lime, cement, lime/slagment, etc). Very ...Read more
Author:Grieve, G; Gouws, SDate:Apr 2010During the manufacture of Portland-type cements, significant emissions of carbon dioxide occur, some of which comes from the burning of fuel in the kiln, and the balance from the chemical dissociation of limestone (CaCO3). In South Africa the ...Read more
