Literature [8] raises a new method to improve the mechanical properties of recycled concrete aggregate (RCA). Tannic acid (TA), a plant polyphenol and the third largest plant component in the world, is used to soak recycled concrete aggregate (RCA) [9].A unique feature of this material is that it can be firmly bound to various surfaces through covalent or non …
The evidence for and against various possible calcium sulphate hydrates is reviewed. The hydrates that exist are calcium sulphate dihydrate CaSO 4 .2H 2 O, calcium sulphate hemihydrate CaSO 4 .1/2H 2 O, and three anhydrous phases : soluble calcium sulphate anhydrite, insoluble calcium sulphate anhydrite, and a high temperature calcium sulphate anhydrite phase. The α- …

It could further be es-tablished that the metastable form is the poly-hydrate. 1. THE POLYHYDRATE (WEDDELITE)-a) Plant crystals-Microcrystals of calcium ox-' Received 10 February 1980.
The attrition of CaO-based solids operating in calcium looping (CaL) post-combustion CO 2 capture systems is an important factor to consider when limestones are selected as sorbent precursors. In this work, four commercial natural limestones with similar chemical compositions but with very different mechanical properties were tested in a 30kWth …
