It will prolong the service life of structures and contribute to the reduction of embodied carbon. The speaker has been involved in some construction projects for joint-less floors & civil engineering structures in the Asia Pacific region. He will introduce the mechanism of expansive concrete, how to compensate the shrinkage, how to estimate the possibility of cracks with some case studies and solutions. He will also introduce the combination of expansive additive with supplementary cementitious material such as GGBS and FA for additional CO2 reduction.
