3 MasterRoc MS 660 PRODUCT AND MANUFACTURER ABOUT THE MANUFACTURER Master Builders Solutions is one of the leading suppliers of concrete admixtures and underground construction solutions worldwide. With over a century of experience in the construction industry, we leverage cutting-edge technologies, a global community of experts at the core of our business, as well as in-depth knowledge of local building needs to provide innovative and sustainable solutions. PRODUCT DESCRIPTION MasterRoc MS 660 is a silica fume slurry designed to improve the performance of concrete by densifying its porous structure. This enhancement provides greater resistance to external influences such as chemical and mechanical stress, making it suitable for a wide range of applications. The slurry is used in wet-mix and dry-mix sprayed concrete, pre-cast and cast in-situ concrete, and high-strength or underwater concrete. It is particularly effective for projects requiring concrete with reduced cement content or thick, stable layers, such as annulus grouting in tunnel boring machine operations. Key benefits include increased strength and durability, improved resistance to external attacks, and reduced bleeding and segregation in fresh concrete. Additionally, it lowers accelerator consumption and minimizes dust in dry-mix applications, contributing to better working conditions.

4 MasterRoc MS 660 PRODUCT LIFE-CYCLE SYSTEM BOUNDARY This EPD covers the life-cycle modules listed in the following table. Product stage Assembly stage Use stage End of life stage Beyond the system boundaries A1 A2 A3 A4 A5 B1 B2 B3 B4 B5 B6 B7 C1 C2 C3 C4 D x x x MND MND MND MND MND MND MND MND MND MND MND Raw materials Transport Manufacturing Transport Assembly Use Maintenance Repair Replacement Refurbishment Operational energy use Operational water use Deconstr./demol. Transport Waste processing Disposal Reuse Recovery Recycling Modules not declared = MND. Modules not relevant = MNR. MANUFACTURING AND PACKAGING (A1-A3) The environmental impacts considered for the product stage cover the manufacturing of raw materials used in the production as well as packaging materials and other ancillary materials. Also, fuels used by machines, and handling of waste formed in the production processes at the manufacturing facilities (if any) are included in this stage. The study also considers the material losses occurring during the manufacturing processes as well as losses during electricity transmission. Silica fume is a by-product of industrial silicon and ferroalloy production. Based on the current allocation methodology from the process itself, it does not carry any CO2 burden. The footprint is determined by treatment, handling, and packing post-production. The main contributors to carbon footprint are Scope 1 emissions related to the reduction of silicon oxides, followed by emissions associated with the extraction of carbon sources. Other relevant contributors are the extraction and transportation of different raw materials. TRANSPORT AND INSTALLATION (A4-A5) Transportation impacts occurred from final product delivery to the construction site (A4) is not modelled. PRODUCT USE AND MAINTENANCE (B1-B7) This EPD does not cover the use phase. Air, soil, and water impacts during the use phase have not been studied. PRODUCT END OF LIFE (C1-C4, D) The product end of life stages (C1 – C4) are not included in this EPD based on the EN 15804 standard special provision for construction products and materials which fulfil the conditions for exemption based on the product being integrated and not capable of separation from concrete at end of life, the product not being identifiable as original based on the physical change after deconstruction and the omission of any biogenic carbon in the product.

6 MasterRoc MS 660 LIFE-CYCLE ASSESSMENT CUT-OFF CRITERIA The study does not exclude any modules or processes which are stated mandatory in the reference standard and the applied PCR. The study does not exclude any hazardous materials or substances. The study includes all major raw material and energy consumption. All inputs and outputs of the not exclude any hazardous materials or substances. The study includes all major raw material and energy consumption. All inputs and outputs of the unit processes, for which data is available for, are included in the calculation. There is no neglected unit process more than 1% of total mass or energy flows. The module specific total neglected input and output flows also do not exceed 5% of energy usage or mass. ALLOCATION, ESTIMATES AND ASSUMPTIONS Allocation is required if some material, energy, and waste data cannot be measured separately for the product under investigation. All allocations are done as per the reference standards and the applied PCR. In this study, allocation has been done in the following ways: Data type Allocation Raw materials No allocation Packaging materials Allocated by mass or volume Ancillary materials No allocation Manufacturing energy and waste No allocation Allocation between products has been minimised through detailing sub-processes. Where allocation has been unavoidable, the environmental burden has been distributed according to parameters viewed as fair and as incentivizing carbon footprint reductions. These parameters include economic allocation and mass allocation. AVERAGES AND VARIABILITY VP- Type of average No averaging Averaging method Not applicable Variation in GWP-fossil for A1-A3 - This EPD is product and factory specific and does not contain average calculations. LCA SOFTWARE AND BIBLIOGRAPHY This EPD has been created using One Click LCA EPD Generator. The LCA and EPD have been prepared according to the reference standards and ISO 14040/14044. Ecoinvent 3.8 and One Click LCA databases were used as sources of environmental data.
