Aggregate Industries has introduced a new range of high early strength concretes. The concretes are specifically designed for use in structural, void-fill, pavement, and track bed applications.
The Strike+ range is available in four different strengths and in various levels of consistency, making it suitable for a number of placement methods, including pump, skip, and direct. The high performance concretes have been formulated with rapid setting times, ranging between 15 min. and four hours. The company has stated that they are essential for use in construction projects where durability is key, in sectors such as road, rail, and infrastructure.
The concretes’ other properties include high resistance to chlorides, low surface absorption, low shrinkage, and high freezing thaw resistance. The company has stated that, as a result, the Strike+ products are well placed to meet specified return to service requirements in compressive strength. In addition, its early strength gain properties can be adapted to meet complex contract specifications.
The products are manufactured and delivered using volumetric concrete mixers, with water only being added to the mix at the point of use. The range consists of specially blended binders, PC52.5N, CEM I (BSEN 197), and carefully selected concrete aggregates (BSEN 1260).
“A greater onus on contractors to deliver ever more complex builds to tighter budgets and reduced deadlines, means that speed, efficiency, and durability during the construction process has never been more critical,” said David Porter, Area Manager of Concrete for the East Midlands at Aggregate Industries. “That is why we have launched our new Strike+ range of high early strength concretes. Its rapid setting times enable users to dramatically increase their productivity when building carriageway replacements, airport hard standings, warehouses, and precast structures. It also provides the enhanced strength and long-wearing properties required on many infrastructure projects.”
