Concrete manufacturing with a low CO2 footprint

The Nanostructure of Low-CO2 Concrete for a Sustainable Infrastructure

Executive Summary The objective of this program is to measure the changes in the properties of the C-S-H gel phase in cement paste as a function of the Ca/Si ratio. The motivation is to better understand the hydration products that form in blended cements with lower Ca/Si ratios than portland cement. The main contribution from Northwestern was to characterize specimens using small-angle neutron...

The carbon footprint of reinforced concrete

Tracking Users Mobility Patterns Towards CO2 Footprint

This research work is based on the development of a mobile application and associated central services for tracking users’ movements in a city, identifying the transportation mode and routes performed. This passive tracking generates useful data about users’ habits, which are then associated with the CO2 emission in the form of a mobility invoice, with the goal of enabling the users to understa...

Planning Approach for Robust Manufacturing Footprint Decisions

The manufacturing footprint strategy of European automotive companies has been determined in the preceding decades by a reduction of labour and operational costs and the development of new markets. Today, the automotive sector is characterised by growing number of logistic-related requirements like customisation, just-in-sequence supply and assembly of vendor parts (FAST 2025, 2013). This leads...

Low Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates

A comparison of concrete containing recycled concrete coarse aggregates and natural coarse aggregates subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct conc...
