Webb10 apr. 1990 · Ettringite and tobermite are concrete-like materials (pozzolans) that bind waste materials in a monolithic, calcium containing solid of high structural integrity. Calcium that is available for pozzolanic activity ("free calcium") can come from the ash alone or from added lime, Portland cement, and/or the residue from flue gas scrubbing … WebbConcrete is an extremely multifaceted material. Able to take any form, texture and colour to enhance the appearance of a building, concrete creates surfaces that can be made smooth, rough and in a range of colours. Often overlooked, concrete is one of the most dynamic and flexible building materials in architectural history.
