The cargo vessel “Port Botany” will be discharging 26,000 tonnes of clinker for Pacific Cement Limited for six days at Lami Bay.

This was confirmed to the Fiji Sun by the company spokesman Mr Sowani Tuidrola.

“The discharging will start soon after Customs Officers have checked the vessel,” he said.

Mr Tuidrola said the company usually ordered clinker from Mitsubishi Cement Company, Japan.

He said a barge was on standby at Lami Bay.

“The clinker will be discharged to the barge and will transport the clinker to the trucks at Lami and later to the company yard.”

According to Wikipedia, clinker consists of various calcium silicates including alite and belite. Tricalcium aluminate and calcium aluminoferrite are other common components. These components are often generated in situ by heating various clays and limestone. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature. The products of the chemical reaction aggregate together at their sintering temperature, about 1,450 °C (2,640 °F). Aluminium oxide and iron oxide are present only as a flux to reduce the sintering temperature and contribute little to the cement strength. For special cements, such as low heat (LH) and sulfate resistant (SR) types, it is necessary to limit the amount of tricalcium aluminate formed. The major raw material for the clinker-making is usually limestone mixed with a second material containing clay as source of alumino-silicate. Normally, an impure limestone, which contains clay or silicon dioxide (SiO2), is used. The calcium carbonate (CaCO3) content of these limestones can be as low as 80%. Second, raw materials (materials in the raw mix other than limestone) depend on the purity of the limestone. Some of the second raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. The clinker surface and its reactions in different electrolytic solutions are investigated by scanning electron microscope and atomic force microscopy.

Pacific Cement Limited manufactures and supplies cement and related products for private and public projects in Fiji, Solomon Islands, Tonga, Samoa, Vanuatu, Tuvalu, Cook Islands, Kiribati, Wallis and Futuna, and New Zealand. Pacific Cement Limited was formerly known as Fiji Industries Ltd. The company is based in Suva.

Mr Tuidrola said measures had been put in place for the protection of the environment during the production of cement.
