Carbonation for the curing of cement-based materials has been gaining increased attention
in recent years, especially in light of emerging initiatives regarding carbon emissions. This …

Partial least squares (PLS) regression models were developed to quantify CaCO 3 in
cement and to study the CO 2 effect on the material matrix. PLS results presented good …

Cement paste is known to react with atmospheric carbon dioxide. Carbonation of cement
paste has long been recognized as one of the causes of reinforcement corrosion. On the …

With the development of the construction industry, global CO 2 emissions are closely related
to the utilization of cement-based materials (CBM). The calcium-silicate-based cement, as …

This article summarizes the existing knowledge regarding the carbonation of cement-based
materials and identified the areas which require further investigations. Available studies …

The accelerated carbonation technology has been utilized in order to enhance the
properties of the recycled concrete aggregates (RCAs) and efficient sequestration of carbon …

The carbonation of portlandite, calcium silicate hydrate (CSH), and ettringite was
investigated at 57% RH and 91% RH using X-ray diffraction, thermogravimetric analysis …

Cement-based materials are widely utilized in infrastructure. The main product of hydrated
products of cement-based materials is calcium silicate hydrate (CSH) gels that are …

At the microscale, CSH gels from alite, or neat Portland cements, has a Ca/Si ratio close to
1.80. At the nanoscale, CSH is described by a defective tobermorite structure which allows a …
