• Modeling the cooling of concrete by piped water. 

  Myers, T.G.; Fowkes, N.D.; Ballim, Y. (American Society of Civil Engineers., 2009)

  Piped water is used to remove hydration heat from concrete blocks during construction. In this paper we develop an approximate model for this process. The problem reduces to solving a one-dimensional heat equation in the ...
• A maturity approach to the rate of heat evolution in concrete. 

  Ballim, Y.; Graham, P.C. (ICE Publishing, 2003)

  This paper discusses the use of the concept of maturity as a means of combining the effects of time and temperature in describing the rate of heat evolution from hydrating cement in concrete. The proposed maturity approach ...
• Early-age heat evolution of clinker cements in relation to microstructure and composition: Implications for temperature development in large concrete elements. 

  Ballim, Y.; Graham, P.C. (Elsevier, 2004)

  This paper presents an assessment of the range and extent of variation of heat evolution of nominally similar cement clinkers from a range of cement production facilities in South Africa. Clinker samples were collected at ...
• The effects of supplementary cementing materials in modifying the heat of hydration of concrete. 

  Ballim, Y.; Graham, P.C. (Springer, 2009)

  This paper is intended to provide guidance on the form and extent to which supplementary cementing materials, in combination with Portland cement, modifies the rate of heat evolution during the early stages of hydration ...
• Effectiveness of the fineness of two South African Portland cements for controlling early-age temperature development in concrete. 

  Graham, P.C.; Ballim, Y.; Kazirukanyo, J.B. (The South African Institution Of Civil Engineering., 2011)

  Temperature gradients due to heat of hydration of cement can cause cracking and present serious structural and serviceability concerns in concrete structures. Engineers use a wide range of strategies to limit the potential ...
• Reflections on future needs in concrete durability research and development. 

  Ballim, Y.; Alexander, M.G.; Beushausen, H.D.; Moyo, P. (CRC Press, Taylor & Francis Group, 2008)

  There is no doubt that, over the past two decades, we have made enormous advances in the understanding and practice of concrete durability. Spurred by the often experienced early deterioration of reinforced concrete ...
• Assessment of two cone penetration test based methods for evaluating the liquefaction potential of tailings dams. 

  Torres Cruz, Luis Alberto (2013-06-12)

  The stability of tailings dams is of great importance to the mining industry. It is well known that soil liquefaction is one of the mechanisms that can compromise the stability of such structures. Given the difficulty ...
• Reflections on future needs in concrete durability research and development 

  Ballim, Y.; Alexander, M.G.; Beushausen, H.D; Moyo, P. (2012-02-03)

  There is no doubt that, over the past two decades, we have made enormous advances in the understanding and practice of concrete durability. Spurred by the often experienced early deterioration of reinforced concrete ...
• Effectiveness of the fi neness of two South African Portland cements for controllingearly-age temperaturedevelopment in concrete 

  Graham, P.C.; Ballim, Y.; Kazirukanyo, J. (2011-04-01)

  In developing an assessment of the quantum and rate of heat evolution from hydrating cement, an important controllable variable is the fineness of grinding of the cement. This paper presents the results of a project in ...
