Early-stage curing temperature has a significant effect on high performance concrete durability and strength. Concrete cures at high temperatures when poured in large volumes due to the autogeneous heat generated by the hydration reactions of cementitious materials. The addition of supplementary cementing materials to concrete reduces the heat of hydration and extends the service life in structures by improving both long term durability and strength. This thesis investigates the effects of early-age curing temperature on the durability and strength of silica fume and fly ash modified concretes. Accelerated test methods were used to measure chloride diffusion in concretes produced with silica fume cement (T10SF) and various levels and types of fly ash replacement. The concrete mix determined to be the most durable with respect to chloride diffusion had 56% of the Type 10SF cement replaced with a moderate-level calcium content fly ash. The use of the Rapid Chloride Permeability Test, (ASTM C 1202, AASHTO T 277) has been widely criticised. Despite a limited data set, good correlation was shown in the results of this research between a two-chamber accelerated chloride migration cell test, and the RCPT.

The book gathers the peer-reviewed contributions presented at the 3rd International Conference on Application of Superabsorbent Polymers (SAP) and Other New Admixtures towards Smart Concrete, held in Skukuza, South Africa, on November 25-27, 2019. It features papers focusing on the behavior of SAP in concrete (in particular the absorption behavior) as well as the effect of SAP on fresh and hardened concrete properties. It also covers topics such as other modern admixtures, in particular rheology-modifying admixtures, including the recently emerging field of bio- or waste-derived admixtures. The conference builds on the experience and summarizes the activities of the RILEM Technical Committee 260-RSC "Recommendations for Use of Superabsorbent Polymers in Concrete Construction" and addresses other prominent research activities in the field of concrete admixtures.

Global warming, caused by a significant increase in the concentration of greenhouse gases (GHGs) such as CO2, has become a concern all over the world. The whole process carbon emissions of the civil engineering industry account for nearly 40% of global energy and process-related CO2 emissions, more than half of which come from the process of producing, using, constructing and dismantling in civil engineering materials and structures, resulting in the embodied carbon emissions. With the acceleration of global warming, warmer and uncertain climates will make engineering materials and structures subject to more severe environmental conditions. A series of durability issues will occur more frequently, such as the significant variations of humidity in air, the chloride-induced corrosion caused by the severe chloride ingress, concrete cracking caused by the expansion of rusts, and more severe carbonation of concrete structures due to the increase in CO2 concentration. The adoption of positive measures to address climate change has become a global consensus, as global warming has led to serious threats and challenges to the survival and development of humankind.

This book brings together 106 papers presented at the Joint Conferences of 2015 International Conference on Computer Science and Engineering Technology (CSET2015) and 2015 International Conference on Medical Science and Biological Engineering (MSBE2015), which were held in Hong Kong on 30-31 May 2015.The joint conferences covered a wide range of research topics in new emerging technologies, ranging from computing to biomedical engineering. During the conferences, industry professionals, scholars and government agencies around the world gathered to share their latest research results and discuss the practical challenges they encountered. Their research articles were reviewed and selected by a panel of experts before being compiled into this proceedings. Combining research findings and industry applications, this proceedings should be a useful reference for researchers and engineers working in computing and biomedical science.
