One of the important facets of The South African Institute of Mining and Metallurgy is its service to its members. One way of achieving this objective is by pursuing an active branch structure. In this Spotlight, Richard Beck, Holder of the Regional Development Portfolio, gives the aims of the Institute's branches, with a short note on each branch prepared by the regional chairman. Aims of the Branches: The primary aims of the Branches of The South African Institute of Mining and Metallurgy are those of the Institute itself: to further the interest of its members, to uphold the status of the mining and metallurgical profession, and to promote the image of mining and metallurgy. Beyond these 'high' objectives, the branches have a special function in providing a more intimate relationship between the Institute and its members. The branches enable members who live outside the Johannesburg area to participate in the affairs of the Institute to an extent that would not otherwise be possible and that they themselves can define. This is achieved through the holding of social events, colloquia, and visits.

The main objective of The South African Institute of Mining and Metalurgy is to identify the needs of the mineral and metals sector of the South African economy, and to initiate the means by which the requirements for technology and scientific knowledge can be satisfied. To achieve this, the Institute organizes schools to promote technology transfer and to satisfy the needs of its members for continuing education by the exchange of technical information, the communication of ideas, and the identification of technological problem areas.

The first joint colloquium between the South African Institute of Mining and Metallurgy and the South African Branch of the Institution of Metallurgists was held in Kelvin House on 23rd April, 1981. About eighty delegates registered, the majority being associated with the local branch of the Institution of Metallurgists. Types of Abrasion and Wear Professor A. Ball, of the University of Cape Town, gave the opening address, which he entitled 'Some Thoughts on Abrasion and Wear'. In his thoughtprovoking talk, he quoted some figures showing that, in the highly industrialized countries, loss by wear and abrasion might amount to about 4 per cent of the gross national product but, in the Republic of South Africa, it was believed to be about 6 per cent of the gross national productprobably associated with the massive influence of mining in our economy. Professor Ball described wear as being of three main types.

On 18th November, 1991, the Department of Chemical Engineering at the University of the Witwatersrand, Johannesburg, held a display of posters to review their R & D activities. Although not a new concept, this series of presentations was the first time that the Department of Chemical Engineering at Wits had undertaken as comprehensive a review in this particular format. It turned out to be a most worth-while exercise, and the many visitors must have been impressed with the quality of the presentations.

"SynopsisCommencement of the next phase of the Lesotho Highlands Water Project is a year or so away from becoming reality. Some 50 km of tunnels in the form of access adits, shafts, diversion tunnels, and main waterways will be constructed. Sprayed concrete will form an integral part of the temporary and permanent rock support systems that will be installed. Furthermore, the use of sprayed concrete as a final tunnel lining solution was proposed as a viable alternative to concrete linings in the feasibility studies that preceded the forthcoming implementation phase.The aim of this paper is to make the reader aware of all the sprayed concrete related issues that engineers tend to grapple with during the design and construction of tunnel projects and other underground works. Primarily, these issues would include selection of applicable design parameters, technical specifications, construction application methods, quality control and, most importantly in the context of final or permanent linings, the durability of sprayed concrete.The International Tunnelling Association (ITA) Working Group (WG) 12 has been tasked specifically to publish a set of recommendations on the Quality and Control of the Application of Sprayed Concrete and the Testing of Sprayed Concrete for Durability. These tasks were also further explored at the recent World Tunnel Congress (WTC 2015) that was held in Dubrovnik, Croatia at the end of May 2015.IntroductionSprayed concrete is presented in a variety of shapes, designs, forms, application methods and accompanying terminologies including shotcrete, gunite, pneumatically applied concrete, and the like. The International Tunnelling Association (ITA) decided to standardize on a single terminology, namely ‘sprayed concrete’, in order to simplify specification, interpretation of guidelines, and codes of practice."
