Research on Recycled Fine Powder Applied in Mortar
The basic properties and its influences on mortar properties are studied for the purpose of using recycled fine powder. Results show that mortar water assumption increases and the compressive strength declines with the increase of recycled fine powder content. Efficient ratio of recycled fine powder is propounded for the first time to reflect the contribution of recycled fine powder with different content to mortar strength. It is greater than 1 and thus has certain contribution to mortar strength when recycled fine power content being less than 28%, which reaches the maximum as being 14%.
