Investigation of Different Types of Cement Material on Thermal Properties of Sustainable Concrete Mixes

摘要

One of the challenges in sustainable development is to optimize the energy efficiency of buildings during their lifespan. Nowadays the applying of different types of cements in modern concretes provide low embodied CO2 with the intrinsic property called "thermal mass" that reduces the risk of overheating in the summer and provides passive heating in the winter. Thermal mass is affected by thermal properties of concrete which it is the ability of the element to exchange heat with the environment and is based on thermal capacity, conductivity, and density. Laboratory experiments measured density, specific capacity and thermal conductivity of sustainable concrete mixes with various percentages of GGBS, PFA, SF. The results contribute to the investigation of the performance of thermal properties performance in sustainable concrete.
