NCC Industry in Södra Sandby, Sweden has been using Sandvik’s latest screening media technology, the WX6500, for over a year The company reports that the first fine screening test panels are still in place and performing reliably. NCC Industry's Stone Materials division said that it has long chosen rubber screening media over wire mesh. The choice is crucial in Södra Sandby, where abrasive quartzite produces excessive wear on metal components. Yet despite its preference, the company said that it had stru

A new super-modifier is born from waste plastic in Italy and a soybean-based rejuvenator from the US spreads from its home market. By Kristina Smith The two bitumen technologies featured this month come from almost opposing sources. One emerges from the human-created plastic waste plaguing our planet, the other from a plant. However, both technologies have been created with the same aims: to increase the life of roads, saving cost and ultimately reducing the impact of road building on the planet. A coll

Carmix says that its 3500 TC production system offers superior comfort to users along with improved ergonomic controls, all-round visibility – and an air-conditioned cabin. A batching unit has a material yield of 3.5m³ with double mixing screws. Mixing and discharge speed is independent from the speed of the diesel engine, and discharge is by reversing drum. A joymix-controlled 600litre loader with a hydraulic door discharges sand or gravel directly into the drum. The unit can travel on slopes greater th

Batching plant supplier Rapid International has supplied the Scottish Collier Group with its first batching plant as it enters the ready-mix and precast concrete market. The plant was installed at Collier’s Goathill Quarry in Fife. Collier Group’s activities have included processing of inert rubble, muck and soil from building sites, transportation of ash from power stations, production of type 1 sub-base, rock armour, single size aggregates including high PSV and manufactured concrete sand from the washi

Thomas Cement has opened a 7,000tonne capacity terminal for the import of binding material in the port of Uddevalla, north of Gothenburg, Sweden. The terminal is strategically important for the Thomas Concrete Group’s Swedish subsidiary Thomas Betong. Last year Betong acquired four concrete plants in Sörmland province and three plants in the Gothenburg region, said Hans Karlander, chief executive of Thomas Concrete Group. Gothenburg is the group’s headquarters. “Gothenburg is also particularly important f

The new MX-20MT mixer/pump from Blastcrete Equipment gives contractors a unit with twice the output of the company’s popular MX-10 Yet the higher-capacity MX-20MT has nearly the same compact footprint as its smaller cousin, according to the US company, based in Anniston, Alabama. It’s mounted to a single-chassis trailer for convenience as well as fast and easy transportation, setup and cleaning. The MX-20MT is CE certified to meet European Union safety standards for equipment operation. It features a 1t

If ready-mix concrete is not an option for underground sealing, stabilisation and grouting, then Blastcrete Equipment’s Mine Mate will step up. The low-profile Mine Mate mixes and pumps concrete material for shotcrete applications. It features Blastcrete’s X-10 ultra high-pressure swing tube pump for the wet-mix shotcrete process. In contrast to the dry shotcrete – gunite - the wet shotcrete process minimises dust and improves visibility making it much safer, particularly for underground use. Featuring a co

The Liantang/Heung Yuen Wai Boundary Control Point project is creating a seventh land crossing, including highways and tunnels, between Shenzhen in China and Hong Kong There are already two control points on the eastern side of the New Territories between China and Hong Kong - at Man Kam To and Sha Tau Kok – to access eastern Shenzhen and Guangdong. All cross-boundary traffic travelling from these points must use busy local roads in Hong Kong and Shenzhen before joining the major highway systems. The US

A new bridge project in Colombia is benefiting from the supply of concrete from CEMEX Latam Holdings The project is to build a new bridge for Colombia’s Río Magdalena 2 Highway, with the road being one of the primary infrastructure projects currently under development in the country. CEMEX Colombia is supplying concrete for several essential elements of the project, including a viaduct over the Magdalena River that will become one of the longest bridges in the country.
