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. 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.

One such approach is the use of Secondary Cementitious Materials (SCM) (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 the CUBE system. 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.

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 with the properties of alkaline activation materials. Development of the mechanical strength of hybrid cements is promoted by the alkaline activation of their components.

PRODUCT RANGE

MAPECUBE 1 Strength enhancer after short curing cycles
MAPECUBE 2 Strength enhancer specific for cements with limestone
MAPECUBE 4 Strength enhancer specific for cements with fly ash or slag
MAPECUBE 60 Strength enhancer for all cements and SCM
MAPECUBE 60W Strength enhancer for all cements and SCM
