CO2-free Concrete

BALKE & PARTNERS

INTRO

Cement production is responsible for roughly 8% of global CO2 emissions. Balke and Partner utilize their extensive global network to locate optimal mineral reserves, such as Basalt, Tuff, Pozzolans, Ash, Limestone, Kaolin, Clay, and others, situated near cement production facilities. This initiative supports the shift toward sustainable, CO2-free concrete solutions.

There are various alternative materials and methods available for producing concrete without relying on traditional cement:

1. GEOPOLYMER CONCRETE

Geopolymer concrete employs inorganic polymers derived from

alumino-silicate materials in place of cement.

Benefits: This type of concrete offers improved durability, heat and chemical resistance, and a significantly reduced carbon footprint.

2. HEMPCRETE

Hempcrete is a composite made primarily from hemp hurds and lime.

3. ASH BASED CONCRETE

This method incorporates industrial by-products such as fly ash or bottom ash as substitutes for cement.

4. CALCIUMSILICATE-BASED BINDERS

These binders consist of silicates, including calcium silicate, which can replace cement in concrete mixtures.

5. POLYMER-MODIFIED CONCRETE

In some concrete mixtures, polymers can replace traditional cement.

Benefits: This concrete type offers enhanced bonding, improved water resistance, and increased flexibility.

5. RICE HUSK ASH (RHA)

RHA serves as a sustainable alternative for concrete production. It can partially replace cement in concrete mixes, enhancing the final product's strength and durability.

CONCLUSION

According to Balke and Partners, the pursuit of concrete without traditional cement is indeed achievable by exploring these alternatives. Each method presents specific advantages and application opportunities. When selecting these materials, it is crucial to consider the intended use, necessary properties, and the local availability of resources. Continuous research and innovation are advancing these technologies, promoting a greater demand for environmentally sustainable construction practices. Balke & Partners is the ideal partner to help you find the right materials and minerals for your concrete production needs.
