Abstract

This paper presents a systematic design approach for an efficient use of OPC in cement-based materials in combination with inert mineral fillers. Functional properties of pastes are linked to Life Cycle Assessment. A new method combination (“Mi-S-S”, mixing-shear-resistance, spread flow, strength test) was successfully applied to identify and characterize proper fillers and to find optimum mix-ratios for eco-efficient pastes consisting of OPC, very fine micro-fillers (MFs) and fine “eco-fillers” (EFs). In mixes, OPC/EF/MF optimized against reference-mixes (i) high packing density, (ii) desired spread-flow and (iii) sufficient compressive strength (CS) was reached, (iv) reducing the environmental impact. Relationships were found to link mix-design parameters (OPC-content, w/c-, w/p-ratio etc.) to pastes' functional requirements (spread flow and CS). An optimum filler content of 20–40 vol% was identified in eco-efficient OPC/EF/MF mixes. Optimized mortars exhibited reductions of up to 37% and 24% in CO2- and embodied energy-intensities, respectively, in comparison to standard OPC mortars.
