US: Thomas, Bennett & Hunter (TBH) has had a site plan to build a new ready-mixed concrete (RMX) plant in Hagerstown, Maryland approved by the Washington County Planning Commission. The concrete producer is moving its operations in the town to a new site, according to the Herald-Mail newspaper. It is hoped that the new RMX plant will be commissioned by the end of 2020.

UK: Aggregate Industries has acquired Maxi Readymix Concrete, an independent readymix concrete (RMX) business based in Leicestershire and the East Midlands. The company operates a Betomix 2.66m³ twin shaft wet batch plant capable of producing 110m³/hr of compacted concrete with a silo capacity of 400t and aggregate capacity of 650t. It was supplied by Germany’s Liebherr and commissioned in 2014.

UK: Hanson has opened a new ready-mixed concrete (RMX) plant in Rochester, Kent, to supply growing demand for construction projects in the South East. The new unit replaces the subsidiary of HeidelbergCement’s former concrete plant in the town. The group says it provides increased capacity, improved productivity, lower power consumption and reduced ongoing maintenance costs.

France: LafargeHolcim France has become the first cement manufacturer to offer tailor-made concrete solutions, with a range of concrete products for eight different applications. These include concretes made with specially adapted cement for thermal insulation, resilience to acid and seawater and optimised CO₂ balance.

UK: Aggregate Industries has released a range of admixture-driven waterproofing solutions, blended with a custom mixes of BASF’s MasterLife WP 799, called Watertight^TM concrete.

Aggregate industries has described the high performance integrated waterproofing systems as ‘insensitive to weather, groundwater and sprinkler systems.’

US: Nano Graphene has launched a concrete admixture. OG Concrete Admix improves concrete’s water resistance by a factor of four and more than doubles the strength, while significantly reducing cracking.

In GrapheneCA’s promotional material, it mentions a lowered carbon footprint amongst the benefits of its admixture for concrete producers, with less cement being required in the production of concrete using OG Concrete Admix.

Brazil: Votorantim Cimentos’ revenue rose by 3.8% year-on-year to US$1.44bn in the first half of 2019 from US$1.39bn in the same period in 2018. Sales growth was driven by ready-mixed concrete and the company’s other businesses as cement sales fell slightly. It reported a profit of US$29.4m compared to a loss of US$72m previously. Its cement sales volumes fell by 6% to 13.8Mt from 14.7Mt.

"In the first half of the year, we achieved net revenue growth and stability in our leverage, even though the Brazilian economy has not yet achieved the anticipated recovery and despite the impact of an atypical seasonality in North America. In this second quarter, we followed our investment plan and inaugurated a new production line of mortar, in Cuiabá, and one of agricultural solutions, in Nobres, both in the Brazilian state of Mato Grosso," said Osvaldo Ayres Filho, Global chief financial officer (CFO) of Votorantim Cimentos. The company added that higher prices in Brazil, growing sales in North America and positive currency effects successfully offset poor results in Turkey.

One of the summer news stories in the UK has been the drama surrounding the near-failure of dam near Whaley Bridge in Derbyshire. Concrete slabs on an overflow spillway fell away after a period of heavy rain leading to fears that the dam could fail inundating the area. Around 1500 local residents were evacuated for about a week as a precaution until the reservoir’s water level could be pumped down low enough for inspection.

No one was hurt in the incident but it has raised questions about the maintenance and renewal of infrastructure and how this fits with changing weather patterns caused by anthropogenic climate change. A sadder example of this is the collapse of the Morandi Bridge in Genoa, Italy in August 2018 that killed 43 people. This was later blamed on decaying steel rods in the structure. There have been similar debates in the US with President Donald Trump’s on-going attempts to push through a US$2tn infrastructure bill to repair the country’s structures. Although, predictably, it is floundering on the question of who is actually going to pay for it all.

In the UK, for example, cement production hit a high of over 15Mt in the late 1980s before declining to a low of 7.6Mt in 2009 and eventually climbing to above 9Mt/yr since 2015. A big cause of that decline was the 2008 financial crash and the subsequent government austerity policies. Yet, even with this taken into account, production was at around 11Mt/yr in the 2000s. How much, if any, of this production capacity gap of at least 4Mt between the late 1980s and the 2000s might be needed to maintain the country’s infrastructure? Southern Mediterranean countries like Spain and Italy offer even starker examples. Italy’s cement production fell to 19.3Mt in 2017 from nearly 40Mt in 2001. Spain’s production hit a high of around 50Mt/yr in 2007 with apparent production (local consumption and exports) falling to around 20Mt in 2018. Much of these declines are due to loss of export markets but the same basic questions remain about how much capacity will be required in the future to maintain and repair existing structures in developed nations. This could be imported but the usual constraints about moving heavy building materials around inland mean than at least some of this cement will need to manufactured locally.

The International Energy Agency (IEA) estimated in 2010 that the world would need 50Bnt of cement between 2015 and 2030. The global cement industry was already producing around 3.5Bnt/yr in 2015 according to the Global Cement Directory 2015 giving it overcapacity even then towards the estimated target. Global production capacity is just under 4Bnt/yr today. Estimates for the cost of global infrastructure requirements in this period range from US$1Tnr/yr to US$6Tnr/yr. The majority of this will go towards new infrastructure in developing countries but a minority portion will be required for maintenance. One study by the Brookings Institution and the Global Commission on the Economy and Climate estimated that developed countries would need around US$2Tn/yr for their infrastructure bills.

A study by management consultants McKinsey & Company in late 2017 reckoned that there was a worldwide US$55Tn spending gap between then and 2035 for infrastructure spending. It estimated that countries like the UK, Germany and the US needed to increase their annual spending on infrastructure as a percentage of gross domestic product (GDP) by 0.5%. Although Italy only needed to improve by 0.2%. Looking at the change in infrastructure investment rates suggests that the European Union (EU) actually started to improve its investment from 2013 to 2015 by 0.2% but that the US did not.

All of this goes to show that the show is definitely not over for building materials producers in developed countries. These industries may be mature but they should not be complacent. Roads need patching up, bridges need replacing and all sorts of other infrastructure projects are required even in places that have them already.
