Holcim, a global building materials company, is working to reduce the carbon footprint of concrete production. They are developing new material formulations and recycling aggregates to lower carbon emissions in construction. Holcim is using renewable and alternative fuels to power cement manufacturing and substituting lower carbon alternatives for traditional cement ingredients. Their low-carbon cement range, ECOPlanet, offers a CO₂ reduction of at least 30% compared to traditional cement. Holcim also integrates low-carbon cements into concrete innovations, such as ECOPact, which combines low-carbon cement with locally sourced materials and incorporates recycled content. Holcim's efforts aim to enhance circularity and reduce the need for new virgin components. They have also developed ECOCycle to reuse construction and demolition materials, allowing their cement, aggregates, and concrete to contain up to 100% recycled materials. Holcim's sustainable building materials have been used in projects around the world, contributing to the reduction of carbon emissions and the conservation of natural resources.

Fort Lauderdale's skyline is being transformed by the construction of a 29-story mixed-use tower, which includes a four-star Omni Hotel. This project is notable for its innovative solutions in handling the complexities of urban development. Balfour Beatty contracted Baker Construction to handle the turnkey concrete package, which involved constructing the hotel, office and convention center space, and a parking garage. The project faced logistical challenges due to its location near the Broward County Convention Center and Port Everglades, resulting in heavy traffic. The project also had to overcome obstacles such as a hydrostatic structural slab, multiple core walls, and various elevated slab configurations. Despite these challenges, extensive planning and collaboration allowed the project team to complete their work on schedule in April 2024. The project required a significant amount of concrete, rebar, and post-tension cable. Once completed in 2025, the hotel and expanded convention center space are expected to have a positive economic impact on the region and contribute to the iconic skyline of Fort Lauderdale.

It has been found that, because of the low water content, the Portland cement fraction in ultra high performance concrete (UHPC) is only slightly hydrated and consequently only exists as an inert particle fraction. In the investigations described here the Portland cement content was therefore reduced and directly replaced by pozzolanic, latent-hydraulic or inert fine powders. In contrast to the usual UHPC production with silica fume, which is used as the fine material for filling the voids in the microstructure of the binder, components with tailored particle size ranges were used here to avoid an excessive surface area caused by the void filler. This optimization of the chemistry and particle size range was carried out to meet the respective requirements in three publicly funded projects: BMBF OLAF "High-performance concrete for all',' EU "Energy efficient Building H-House" and BMBF "C3 Carbon Concrete Composite, high performance concrete B2 base project" Reactive synthetic oxides, with which additional hydration reactions can be controlled during the dormant phase of Portland cement hydration, were also used. The results were essentially binder compounds that could be mixed homogeneously in a cement plant and then used with the aggregates available in a concrete plant to produce a UHPC that is easy to handle. The additional silos that would otherwise be needed in a concrete plant for storing silica fume and other fine materials for producing UHPC are no longer required as a result of the binder compounds produced in a cement plant. Compared with the usual UHPCs produced with silica fume, the optimized particle size grading with industrial homogenization has the effect that UHPC can be produced even in simple mixers. Optimization of the binder compounds leads to an extremely dense microstructure of the binder in the hardened UHPC, which, as a result, is characterized by special properties, such as durability and ASR resistance, even with particularly critical aggregates. There are descriptions of other concrete properties and the associated investigations that were carried out. Some examples describe possible applications of the UHPCs produced with these binder compounds, in which production of machine beds with these concretes has already become a commercial application. The use of less than 50 mass % Portland cement clinker in the binder compounds indicates also a way to CO2 reduction. [ABSTRACT FROM AUTHOR]

This paper and the lecture at the annual ACA Conference celebrate Percival Faraday Thompson, (1885- 1951), a metallurgist and chemical analyst, generally considered a corrosion research pioneer in Australia. P F Thompson knew of electrochemistry, in fact he practiced at a time when there was still controversy as to whether corrosion of metals was electrochemical in nature. Electrochemistry forms a key part of many aspects of our lives as it does with the durability of steel reinforced concrete structures and buildings as well as in their repair and protection. Electrochemistry is relevant for the passive film that develops on steel reinforcement when it is placed in concrete. There are several degradative processes which affect some reinforced concrete structures the most common of which is corrosion of reinforcing steel. Electrochemistry is again relevant here. Some concrete structures and buildings require repair and protection during their service lives and electrochemistry is relevant when it comes to aspects of some concrete repair and protection technologies including patch repair, coatings and penetrants, corrosion inhibitors and cathodic protection.
