Rice husk ash as supplementary cementing material to inhibit the alkali-silica reaction in mortars
Revista IBRACON de Estruturas e Materiais, 2021 : Alkali-silica reaction (ASR) is one of the most harmful distress mechanisms that affects the durability of concrete worldwide. Yet, it has been found that ASR-induced expansion and distress may be prevented by the appropriate use of supplementary ...

Evaluation of Pozzolanic Reactivity of Artificial Pozzolans [PDF]
Materials Science Forum, 2012 Pozzolanicity is a very interesting issue regarding building materials, as a way to enhance mortars and concrete durability. This property results from the reaction between calcium hydroxide and silica and alumina based materials. Different types of natural and artificial pozzolans show pozzolanic activities that differ depending on the materials ...
