Lytag Aggregate Industries will be transforming the London skyline with the £250 million redevelopment of 100 Liverpool Street. The high-profile redevelopment is part of the wider Broadgate campus adjacent to Liverpool Street station and it involves demolishing 50% of the original building and rebuilding new infills in structural steel with the addition of three new floors to a create modern, mixed-use space. A key requirement for the main contractor, Sir Robert McAlpine, was to source a concrete solution which would enable more floors to be cast without compromising the dead load of the overall structure. The obvious choice, then, was to use Lytag from Aggregate Industries’ highly innovative lightweight aggregate solution, which can effectively reduce the composite deck concrete slab load by approximately 25% over normal weight control while offering the same level structural performance – enabling 100 Liverpool Street to – literally — reach new heights. In addition, Lytag is made from secondary aggregates; therefore offering a much more environmentally friendly alternative to standard concrete. Thanks to its unique properties, it can help to significantly reduce the amount of material required on a project, along with the associated carbon emission produced in delivery. “The redevelopment of 100 Liverpool Street is a major milestone in Broadgate’s evolution into a world-class, mixed-use destination for London. This project wouldn’t have been structurally or architecturally possible without Lytag and its unrivaled capabilities. Not only did it enable us to take the project from conception to construction, and create a superior sustainable high rise structure but it was also instrumental in helping the building to achieve an Excellent rating in BREEAM,” said Barry Mellor, Commercial and Technical Manager for Lytag. Working with its specialist London Concrete unit, Aggregate Industries has supplied 5000m3 of Lytag to the project, with the building featuring an array of sustainable features that complement the significantly reduced carbon footprint. As a result, 100 Liverpool Street is expected to receive an Excellent rating in BREEAM.
A new upmarket commercial build in Edinburgh city centre benefited from Aggregate Industries’ innovative Lytag, when it came to helping to lighten its load. Located in the heart of the city’s Exchange District, the £24 million 2 Semple Street development has been designed to help alleviate the Scottish Capital’s chronic shortage of Grade A office accommodation. The newly-opened building boasts 45,000 sq ft of cutting-edge office and retail space, over five storeys. In terms of the flooring specification the challenge for awarded concrete and screed specialists, Advance Flooring Solutions was to procure a concrete solution which would enable minimal size slabs and help reduce the overall dead load of the building. The specialist then chose Lytag from Aggregate, which is a highly innovative lightweight concrete that can effectively reduce the dead load of approximately 25% over normal weight control, while offering the same level of structural performance. “Lytag is a fantastic product which was well-matched to this high calibre project for the Scottish capital. Supported with a meticulous delivery plan, the concrete supply was first-class from Aggregate Industries – we’d like to pass on our thanks to all involved,” said Stephen McKenna, Commercial Manager at Advance Flooring Solutions. In total, 744 m3 of Lytag was supplied for the completion of the five floors over the course of eight months. This was supported with a robust delivery framework ensuring that all batches arrived on time and to the exact specification – thus negating the risk of cold joints. In production for more than 50 years, Lytag secondary aggregate is made using innovative technology which transforms fly ash into small pellets which are then heated to 1,100°C. The pellets formed are rounded in shape and range in size from 14 mm down to fines and can be used as a superior, consistent, lightweight aggregate.

Building materials supplier Aggregate Industries has unveiled its Pro Pitch Elite, which is a new, infill sand that claims to have the best drainage rates of any other on the UK market. This solution would help ensure sporting action isn’t interrupted when adverse weather hits. “Extreme weather conditions are a growing concern when it comes to the construction and maintenance of synthetic sports pitches,” said Tom Wise, general manager at Garside Sands, Aggregate Industries. “As such, this has spurred us into our laboratory to design and rigorously test our biggest product innovation in more than 20 years. As a result we can launch Pro Pitch Elite, the ideal solution for enhancing and sustaining sport facilities by ensuring playability all year round, even in areas of extreme rainfall.” Specifically developed to include larger rounded particles, the Pro Pitch Elite infill sand provides greater void space through the playing surface of synthetic sport pitches. During recent laboratory testing, it was also claimed that the product is able to drain 116% better than the most popular competitor of sand available, all due to its absorbent characteristics. “Due to its technical grading, ProPitch Elite has been proven to aid with effective drainage, even outperforming our market-leading Pro Pitch 2EW infill sand, as demonstrated during robust lab testing. For sports clubs looking to provide first-class playing surfaces, even in extreme weather conditions, this revolutionary solution will not disappoint,” added Tom Wise.

Aggregate Industries, the leading construction material supplier, has proved its unrivalled credentials once again in its recent work at the ground-breaking Woodsmith Mine development in North Yorkshire. The £2 billion development will constitute one of Britain’s biggest mines; to incorporate a vast mine head at Woodsmith Mine, Sneaton, with shafts 4,921ft (1,500m) deep, and a 23-mile underground tunnel to transport the potash to Wilton International near Redcar. The project needed the supply and delivery of a vast high quality, hardstone aggregate that was to be used for road construction and ground stabilisation works; therefore the contractor Collins Earthworks called for the services of Aggregate Industries. “Having worked on numerous projects of this size, we were able to apply our learnings to ensure an even more robust approach to the aggregate supply. From working closely with Collins Earthworks at the inventory stages, we have put a stringent plan in place to ensure a continuity of supply without disruption, ensuring the teams have the exact specific technical and quality specification of aggregate as and when they need it,” said John Taylor, sales manager, Aggregates North. During the period of May to December 2017, Aggregate Industries’ specialist team has supplied 81,000 tonnes of Type 3 sub-base aggregates and 9,000 tonnes of Type 1 sub-base aggregates, constituting a total of 90,000 tonnes. A further 20,000 tonnes of material was provided during January and February 2018. In order to effectively and sustainably manage the scale of supply demands, material has been sourced from the business’ Glensanda quarry and shipped to the nearby Teesside port, before being road hauled direct to the project. This approach has enabled the team to deliver in excess of 500 tonnes per day, while operating a stringent quality procedure to ensure the material exceeded the structure and strength values required for the project. “I would like pass on my thanks to Aggregate Industries for providing such a swift and efficient approach to our aggregate requirement which has been vital to keeping the project on schedule. Working on a project of this calibre and scale, it is vital to partner with genuine experts with not just the product capabilities but the expertise behind it, and the team haven’t failed to deliver. I’m sure this relationship will continue as we progress the project over the next four years,” commented on the project Dave Shaw, site manager at Collins Earthworks.
