Above or below ground mining activities require materials to be of an exacting standard and to meet high safety requirements. Technicrete has a unique range of pre-bagged concrete mixes as well as heavy-duty blocks which not only meet these safety concerns but offer effective and cost effective solutions for applications in the mining sector.
The pre-bagged products from Technicrete offer an all-in-one solution such as concrete in various strength grades, high abrasion resistant concrete, pumpable concrete and special grouts, all of which can be tailor-made for specific solutions.
The pre-bagged concrete mixes are used for the construction of dams, floors, box fronts, drains, sumps, foundations to machinery, sprayed concrete for support and abrasion resistant applications.
Wide range of specialised options
Some of the specialised pre-bagged mixes include Ore Pass Lining which is a special concrete that is used for the lining of ore passes and underground silos where high abrasion resistant properties are required. It is easy to mix and place with minimal vibrating required.
HT Wetcrete is a pre-bagged wet shotcrete mix for use in underground support, rockface lining, or in structural repair situations. Two versions are available the fibre-reinforced or the non-reinforced types both providing excellent pumping characteristics. HT Wetcrete drastically reduces rebound characteristics, whilst rebound losses are normally reduced to 5% of total material sprayed. This offers the customer lower wastage and cleaning costs.
The Drycrete product is a dry shotcrete mix for use in underground support, rockface lining, or in structural repair situations. It can be supplied with or without steel fibre reinforcing or polypropylene reinforcing. Quick set characteristics are available for applications where an early strength gain is required.
Roof Bolt Grout is a pre-bagged cementitious grout material for use in rock anchor support. It can easily be pumped using different types of pumping equipment and is supplied in standard, medium or quick set materials providing a choice of required support characteristics. The Standard set Roof Bolt Grout has a pull-out strength that exceeds 10 tons at 24 hours (tested using 300mm pipe section pull out test), when the correct water/cement ratios are used. The product does not segregate during pumping operation.
Other specialised pre-bagged options include: Buildmix, Boxcrete, HSWR, Pumpcrete, Novax, Plastermix, Technimix, TSL and Voidcrete, all of which have specific applications for use in the mining sector.
Key factors in the successful application of the Technicrete pre-bagged cement products are: water/cement ratio. Compaction, mixing, curing and the cement type. All products are manufactured to ISO 9001:2015 quality assurance programmes with daily testing conducted. These reports are available to mine quality officers. All of the materials used in the manufacturing process are compliant with SABS specifications.
Some of the benefits associated with pre-bagged material includes: cost efficiencies, correct mix design without guesswork, easy transportation and handling, quality assured performance by independent testing authority with consistent performance of final material throughout the projects lifespan.
The technical team at Technicrete is available to assist with any specific application requirements customers may need.
Technicrete is part of the IS Group of companies which includes Rocla.
