Strain Hardening Ultra High Performance Fiber Reinforced Concrete (SH-UHPFRC) were used successfully over the last 8 years in numerous cast in place rehabilitation applications as long lasting waterproofing layers (20 to 30 mm thickness) and, combined with ...
High-performance concrete is sensitive to early-age cracking, mainly due to its rapidly-developing autogenous shrinkage. Autogenous shrinkage and internal relative humidity (RH) decrease are direct consequences of the emptying of capillary pores due to cem ...
The production of Portland cement accounts for 5 to 8% of the global anthropogenic CO2 emissions. In the past years, the cement industry has attempted to reduce this contribution by the use of mineral additions on the cement or in the concrete mix. The typ ...
Concrete is the building material with the greatest potential for meeting the increasing housing demand in developing countries. Locally available materials should be considered as cement replacement in order to lower the costs and the environmental impact ...
This paper discusses the results from an experimental investigation conducted to study the effect on using cellulose fibres as cement replacement on the properties of lightweight cement composite. The fibres were recycled from waste paper and packaging and ...
Through a collaborative research effort between the Ecole Polytechnique Federal de Lausanne and CIDEM a new kind of cementitious binder has been developed based on the synergy between calcined clays and limestone. Industrial trials carried out in Cuba duri ...
Supplementary materials that are utilized to replace ordinary Portland cement (OPC) decrease the workability of the cementitious mixtures and superplasticizers are usually added to cement to control their fluidity. In general, current superplasticizers are ...
The sulfate attack is known to influence the durability of concrete. In general, significant damage due to sulfate interaction results in the structural breakdown of the concrete structure. However, the precipitation of thaumasite due to sulfate concentrat ...
This presentation seeks to investigate the processes through which modern roads are conceived and realized. This approach can not only contribute to identify some of the main spatial characteristics of the non-dense urban territories, but also enables to u ...
Buckling-restrained braced frame performance at high drifts is improved by providing beam splices that reduce demands in the gusset regions. Existing experimental data only consider web splices without a slab present. An alternative top-flange splice, prop ...
