M.Ing. / Maintaining and repairing building stock, repair and replacement of the infrastructure, has been a facet of the European building industry for more than 50 years. Deterioration of structures to a level that renders them unusable is a more recent occurrence in South Africa. World-wide changes in the proportion of construction expenditure on new construction and repair and refurbishing of existing structures has occurred only the last two decades. Today, nearly 50 % of such expenditure is on repair and renovation in comparison to proportions of 30 % of previous years. Projections indicate that this trend will continue at least to the next coming century. 1171 Such a substantial proportion of construction expenditure must be expected to influence the market for repair materials, specialized techniques and services. Therefore, a good understanding of the all range of modern concrete repair materials, associated techniques and services as well as latest developments in concrete rehabilitation technology is a prerequisite for designers and users of concrete structures. The following pages attempt to present the basic background of modern concrete repair approaches with regard to the intended use of building structures. They will also deal with the management of a repair project with realkalisation as a remediation strategy. The present condition of the Rand Afrikaans University main campus buildings will serve as a case study model.

M.Tech. (Civil Engineering) / Recoverable anchor screws are widely used in the construction of massive concrete structures such as dams, channels, tunnels and multi-story buildings to fix temporary cantilever forms. Attempts have been made before to quantify the failure capacities of recoverable anchor screws. However, such tests were conducted and reported on more than 25 years ago and were limited to a small number of tests on concrete strengths not exceeding 20 MPa, whereas most concrete constructions now exceed such strengths. The aim of this dissertation was to review the existing theories on the use of concrete anchors in practice and to apply the appropriate theories to recoverable anchor screws. In doing so, the overall shear strength of these screws was determined by considering existing theoretical standards and norms, and by testing the tensile capacity in the laboratory. The failure behaviour of recoverable anchor screws in various concrete strengths and construction applications is reviewed and is discussed based on both theory and the laboratory results obtained. The empirical formulas derived for the practical use of recoverable anchor screws are presented in standard form. These formulas provide an easy reference for engineering professionals in practice to determine the load capacity of recoverable anchor screws in various concrete strengths and construction applications. In conclusion, the required future research on recoverable anchor screws is presented.
