To sustain the decarbonization of the cement industry, identifying new sources of
supplementary cementitious materials (SCMs) is crucial. This review paper examines recent …

The production of portland cement is among the major contributors to greenhouse gas
emissions that adversely affect the environment. Identifying sustainable materials to partially …

The low reactivity of steel slag limits its large-scale application in building materials.
Mechanical activation is reported to increase the reactivity of steel slag, but most of the …

It is well understood that the partial replacement of portland cement with pozzolans in
sufficient proportions results in improved long-term performance of concrete. However …

Geopolymers have been a frequently studied topic during the last decades due to waste
materials utilization, low energy demands, and low carbon dioxide emissions related to their …

ASTM C618 and AASHTO M 295 specifications for fly ash represent the primary documents
used by US state and federal agencies to determine the suitability of a fly ash source for use …

In this study, several tests for supplementary cementitious materials (SCMs) were evaluated
to find the best methods to rapidly screen out inert materials, measure overall reactivity, and …

Declining supplies of quality fly ash in many parts of the world necessitates a search for new
sources of supplementary cementing materials (SCMs) to meet the growing demand for …

The availability of fly ash for concrete has decreased due to the shutdowns of coal-fired
power plants. Alternatives to conventional fly ash are needed to ensure sustainable and …

The ASTM C311 strength activity index test is a potentially flawed test because inert
materials are known to be able to pass the test. The early age of testing, low fly ash …
