CEMEX has played a key role in a highway construction job in Egypt. The company has supplied 130,000m3 of concrete that has been used for the construction of the new Cairo–Suez highway project. The project is of note as this is Egypt’s first concrete highway and if it proves successful, more are likely to be built using this construction method. The 35km road is of major importance to Egypt also as it connects the capital, Cairo, with the seaport city of Suez, two of the nation’s most important economic cen

A Chinese quarry is using crushing equipment from Sandvik to help meet customer demand. This leading Chinese aggregate supplier has invested in four CH870 cone crushers supplied by Sandvik Construction. These up-to-date crushers have been acquired by the company to help produce high quality aggregate for the company’s customers’ increasing requirements. Zhongshan Xinlong Aggregate is located in Zhongshan City, Guangdong Province, China. From this and other locations, the company acts as a key producer and s

Versatility and productivity are key drivers for the concrete plant sector - Mike Woof writes. The days of most construction machines being expressly designed and built for a single specific purpose have gone. These days construction equipment is largely intended to be versatile and adaptable, allowing it to be operated in a wide array of applications and duties. New concrete plants are designed too for mobility as this allows users to set up highly productive equipment quickly on basic sites, with little p

An Indian quarry facility has seen increased uptime and gains in overall efficiency due to the installation of new wear components in its crushing system Installing new distributor plates in this Indian granite quarry has increased its plate operational lifetime by 400-500%. Panchami Stone has fitted the unique HX900 plates to the 85 HP rotor of its Sandvik Construction CV218 VSI, reducing its replacement costs by 50%. The Panchami Stone granite quarry is located 60km from Bangalore, in the south of I

IROCK Crushers says that its TS-522 Heavy Duty Screener suits use in medium- to large-scale operations. The introduction of this unit brings the firm’s range of screens to five and this model suits applications such as recycling, sand and gravel extraction, or as a part of a crusher circuit. Built for high productivity, the TS-522 features extra hopper capacity, class-leading screening area, and the firm claims that it offers the highest stockpiling capability of any unit in its class. The TS-522 is powe

Advances in asphalt plant technology were in major evidence at the bauma 2016 exhibition in Munich - Mike Woof writes One of the most apparent developments at bauma 2016 was the strong focus on asphalt plant technology. The massive physical presence of the asphalt plants could be seen from a distance, right across the showground, particularly the 50m-high machine Benninghoven had opted to exhibit. However, other plant systems from rival firms Ammann, Lintec and Marini, as well as Turkish company E-MAK, c

The Prachuap Khiri Khan region of Thailand is well known for producing high quality aggregates, with four quarries and six concrete plants in operation. A key producer is Tabsakae Granite, which now operates a complete mobile crushing and screening plant. The Sandvik Construction QJ341 jaw crusher, QH331 Hydrocone crusher and a QA451 triple deck Doublescreen are now delivering high production of quality aggregates. Tabsakae Granite operates a quarry and a concrete plant in the Prachuap Khiri Khan region

Scientists at MIT - the Massachusetts Institute of Technology, in the United States - have reportedly developed a type of concrete that may be stronger and more durable than traditional cement. According to the MIT News, a paper recently published in the journal Construction and Building Materials, scientists compared cement paste with the structure of natural materials including bones, shells and sea sponges. These are exceptionally strong because of the way they are arranged at both the microscopic lev

Researchers at the University of British Columbia (UBC) in Canada believe they may have discovered a cure for ‘concrete cancer’, which afflicts many concrete structures. The Canadian claims for a concrete cancer cure revolve around a novel method for producing concrete using discarded glass. Researchers at UBC’s Okanagan campus were able to reduce the chemical reaction that previously caused glass-fed concrete to weaken, expand and crack. This reaction is widely referred to as concrete cancer. “Every

Rapid International has supplied the Gallagher Group, based in the UK, with a new Rapidmix 400CW mobile continuous mixing plant. The Rapidmix machine is operated primarily at the group’s Hermitage Quarry site and is transported to site if haulage presents an issue. Gallagher Group, in the south-east county of Kent, is a building, civil engineering, aggregates and property development company. The group has already purchased a 3m3 Rapid pan mixer for installation in a concrete batching plant system.
