Green Sense Concrete

 

Introduction

Environmental policy and sustainability are core issues within the concrete construction industry. Producers and contractors are increasingly being expected to preserve natural resources while continuing to produce quality products, and thus are searching for construction methods, practices, and products that will promote these objectives. The shift to an environmentally conscious marketplace requires the innovative development of products, practices and procedures.

The Technology

With Green Sense Concrete, BASF offers a revolutionary advanced concrete mixture proportioning service that achieves new levels of performance, economics and sustainability. Green Sense Concrete is an environmentally preferable, cost-effective concrete with optimized proportions in which supplementary cementitious materials, non-cementitious fillers, or both, are used with specially formulated BASF admixtures from Master Builders Solutions, to meet or exceed performance targets.

Green Sense Concrete is a novel concrete that, relative to a baseline reference mix, attains desired setting characteristics, strength, durability and, if needed, a higher workability at a reduced cost to the producer. The innovative Green Sense Concrete allows producers to increase their profitability, provide the contractor with a user-friendly mix that pumps and places efficiently, and offers the opportunity to positively influence the environment.

Why Green Sense Concrete is a sustainable technology

  • Uses advanced mix optimization techniques to increase the amount of supplementary cementitious materials (e.g. Pulverised Fuel Ash, Ground Granulated Blastfurnace Slag)
  • Lowers energy demands, CO2 emissions and other environmental impacts per unit volume of concrete produced
  • Uses inert filler materials that may otherwise end up in landfills


Green Sense Concrete Service Concept

The Green Sense Concrete mix optimization service begins with selecting the performance targets for a specific application. BASF then analyses locally available raw materials, determines the reactivity levels of cement and supplementary cementitious materials, and matches their performance to regionally formulated chemical admixtures. The combination of BASF’s proprietary, advanced mix optimization software and proportioning expertise results in a customer and application-specific mix design that is economically and ecologically optimized.

Benefits of Green Sense Concrete

Green Sense Concrete is optimized for cost, aesthetics, performance and environmental impact, so many tangible benefits can be realized by the entire construction team.

Producer:

  • Optimized and economical concrete composition cost
  • Faster truck discharge time - better fleet utilization
  • Desired setting time, workability retention, and strength performance

Contractor:

  • Highly workable concrete
  • Good pumpability and finishing characteristics
  • Faster placement and production
  • Consistent concrete performance

Owner:

  • Desired aesthetics and durability performance
  • Lower shrinkage and cracking potential
  • Contributes towards sustainability accreditation schemes

Environmental Agencies/Community:

  • Less cement used per cubic metre of concrete produced and, therefore, less energy and CO2
  • Less by-product materials targeted for landfill
  • Lower overall environmental impact

Quantifying Sustainability

Third-party validated tools and services allow BASF to evaluate and compare the sustainable benefits of products to help construction professionals make informed decisions. Information about BASF's Life Cycle Analyzer and Environmental Product Declarations service is below.


Transparency and documentation through Life Cycle Analyzer

A clear documentation and the transparency of the entire construction process also play a significant role in the certification process. This is exactly what BASF’s Life Cycle Analyzer can be used for. The special software enables concrete producers and operators to significantly improve process efficiency, energy consumption, selection of materials and quality. The combination of market know how, research competence and consultancy expertise makes the Green Sense Concrete technology from BASF an elaborated, field proven concept for sustainable construction.

The concrete Life Cycle Analyzer tool calculates and compares the economic and ecological parameters of concrete mix-designs

  • Assesses the environmental footprint of ready-mixed and precast concrete based on EN 15804.
  • Allows quick calculation of environmental indicators and cost impact for real concrete mix-designs.
  • Allows direct comparison of different scenarios and varying production, installation and disposal situations.
  • Delivers a comprehensive report as basis for concrete EPDs, and input for green building rating schemes (BREEAM, LEED, DGNB, HQE).
  • Supports concrete manufacturers and users in improving process efficiency, energy and resource saving.

Master Builders Solutions helps to translate sustainability performance into relevant marketing arguments

  • Only documented and quantified improvements in sustainability are relevant for certification.
  • We create comparability of the sustainability indicators for different concrete mix-designs. Thus, improvements can be strategically assessed and implemented.
  • We offer relevant arguments enabling sustainable solutions to be placed in the concrete industry.
  • We help in implementing economic and environmental improvements to enhance your competitiveness.
  • Together we can make cost-effective rating improvements in the sustainability certification by achieving mix-design optimizations.

Environmental Product Declaration (EPD) Service for Concrete

An Environmental Product Declaration (EPD) is an ISO 14025 Type III environmental label that presents relevant and verified environmental information about goods and services, in this instance concrete, from a life cycle perspective. Each concrete EPD reports cradle-to-gate environmental impacts for a cubic meter of concrete. EPDs are often compared to nutrition labels for food products. However, the EPD presents environmental impacts rather than nutritional facts.

What does the BASF EPD service include?

Our team of experts will create an EPD report and provide a seamless process to completion. BASF manages the entire process, including life cycle assessment based on a concrete producer’s mix design, submission for third-party critical review and registration of the final document through the Program Operator. A final, professionally developed registered EPD will be placed on the Program Operator’s website and is available through a unique URL on the producer’s website.
