Summary on Grant Application Form |
|
Blast furnace slag has latent hydraulic properties, giving considerable potential for commercial use in addition to its widespread use as a partial replacement for Portland cement, notably in alkali-activated slagg (ASS) and slag-calcium alumina cement (CAC) concretes. Use of AAS concretes is already well established in China and the former USSR, but their further application is hindered by lack of research into setting, hydration and durability. Slag/CAC blends are new materials whose chemistry and potential is not yet fully established.The programme brings together experts in cement and concrete from three institutions, using complementary approaches and techniques. Part 1 will examine the setting and hydration of the materials and the factors determining the reactivity of the slag, using SEN (with image analysis) TEM and NMR. Part 2 will study rates of chloride ingress into slag-based materials and chloride-induced corrosion of reinforcing steel. Electrochemical techniques will be used to study initiation and growth of pits and products characterised.
