A complete portfolio of solutions and services as a contribution to reducing the environmental impact of the production of concrete

Concrete is far from being considered a sustainable material, particularly due to the massive amounts of CO2 emissions associated with the production of Portland cement. In 2014 CO2 emissions from the cement industry amounted to 2.2 GT, the second highest the second highest contributor of direct industrial emissions of CO2.

Amongst the various levers in the hands of the cement industry to control greenhouse gas emissions and limit global warming to 2°C by 2100, relative to preindustrial levels (2DS Scenario), the industry has a number of innovative technologies that will assist in reducing its carbon footprint. These include carbon capture and reducing clinker/cement ratio. These options and solutions are paving the way to a reduction of cumulative CO2 emissions in line with the roadmap for 2050.

One such approach is the use of reactive additives (such as blast-furnace slag, fly ash and natural pozzolans) to partially replace clinker in the manufacture of cement. This is a fundamental part of the strategy enabling the entire chain to reduce CO2 emissions by 55% by 2030 and to achieve Carbon Neutrality by 2050.

The use of cement with lower clinker content and recycled aggregates in concrete production presents several challenges however for the concrete industry. Mixes generally will demand increased water contents, achieving and maintaining optimal theological properties and, the slower development of the mechanical strength at both early and late stage.

At Mapei we are committed to improving the sustainability of the construction industry, whilst supporting our customers in this very dynamic environment. To this end we have developed a range of admixtures that can reduce or eliminate these problems the industry faces as a result of the changing performance of its cements and aggregates. Ensuring the industry meets the environmental targets set whilst maintaining concrete performance at all stages.

The complexity of this challenge is increased further due to the regionality of the concrete industry. In recognition of this Mapei has developed the CUBE. An integrated approach that helps the concrete industry overcome the difficulties of reduced clinker cements and aggregates of varying quality through the various phases. Production, placement and in situ. CUBE actively helps the industry maintain its high standards whilst reducing the climatic impact. Beyond the physical performance of a concrete developed by the CUBE it is possible to actively track and measure in real time the impact via digital monitoring.

The CUBE from Mapei helps the concrete market become more sustainable.

technologies


Thanks to the use of propriety technology based on nano-compounds of silicate hydrates, our patent pending system, CUBE represent the fundamental cornerstones of the next generation of admixtures for the new cements with reduced clinker content

Secondary Nucleation (SN)
The addition of nano-composite silicate hydrates produces hydration reactions more rapidly and diffusely in the cement paste.

Augmented Pozzolanic Reaction (APO)
The combination of nano-compounds of silicate hydrates with retarding accelerators produces a more powerful pozzolanic reaction, thereby enabling faster development of mechanical strength after both short and long curing cycles.

Alkaline Activation (AA)
The new hybrid cements have a smaller carbon footprint and combine the properties of OPC (20-30%) with the properties of alkaline activation materials (70-80%). Development of the mechanical strength of hybrid cements is promoted by the alkaline activation of their components.
