An integral part of any shotcreting operation is the cement, which needs to be of a high quality to ensure safety standards are met in mining operations.

 

As a major supplier of Western Australia’s cement for shotcrete to the mining industry, BGC Cement is highly aware of the importance of producing a product that meets these stringent quality and safety standards.

 

“If a site requires ground support in mine tunnelling operations they need to make sure their cement is of sound strength, compatible with additives and manufactured to stringent Australian standards” BGC Cement Sales Manager Robert Turkovic said.

 

“We understand the requirements of the industry, especially around continuous quality monitoring, on- time delivery, cement storage options, supply flexibility and reporting.”

 

Mr Turkovic said an important part of the process was the testing and guarantee of cement quality.

 

“Our cement is manufactured to Australian Standard AS3972, with the quality overseen by BGC Cemtech,” he said. “BGC Cemtech is WA’s only NATA-accredited cement laboratory, with a team of 15 staff.

 

“We do testing every day on both raw material inputs and finished product prior to dispatch. As an added service, we can also supply our clients with a monthly NATA test certificate so they are comfortable in the knowledge the product they receive is of a high quality.”

 

Various tests of additive/accelerator suppliers further ensure optimised shotcreting performance.

 

An accelerator is a material, usually added at the shotcrete nozzle, that increases the rate of hydration of the cement. This is generally called a dry-mix shotcrete process, where cement and aggregates are batched, mixed and delivered into a machine.

 

“This testing is usually based around setting times and high early strength,” Mr Turkovic said.

 

BGC Cement is currently in the process of building a 21,000sqm cement and lime distribution depot at Anzac Drive Industrial Estate in Kalgoorlie.

 

The facility will open later this year and will help BGC Cement better service the Goldfields region by offering sharper delivery times and mitigating the risk of demurrage.

 

Mr Turkovic said BGC’s fleet of prime movers and over 100 tankers provided a holistic supply for the manufacture and delivery of the cement to site up to 2500-3000km away from Perth.

 

The new Kalgoorlie depot will expand the company’s mining-related capability, complementing existing facilities in Port Hedland, Karratha and Darwin.
