Pozzolanas as additives for grouts: an investigation of their working properties and performance characteristics

摘要: Abstract Grouting aims to address a lack of adhesion occurring within the render layers and support wall painting through addition an adhesive material with bulking properties. It is often desirable that grout should set in absence air, one way achieving this by using lime-based pozzolana, which will react calcium hydroxide form stable insoluble compounds possessing cementing This paper characterizes number pozzolanas currently used for grouting paintings on calcareous renders, assesses working properties performance characteristics grouts made pozzolanas. The significance method sample preparation discussed.
