X-ray computed tomography (CT) is a non-destructive technique that offers a 3D insight into
the microstructure of thick (opaque) samples with virtually no preliminary sample …

Volcanic ashes are pyroclastic materials commonly found in many regions of the world.
Many deposits of volcanic ashes are unexploited, despite their potential interest for several …

Increasing closed pore volume in hard carbon is considered to be the most effective way to
enhance the electrochemical performance in sodium‐ion batteries. However, there is a lack …

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 …

The demand for segment concrete increases rapidly with the expansion of urban rail transit
and underground space, which may lead to carbon emissions (CE). In the production of …

The most practical sustainable development options to safeguard the local ecology involve
reducing the use of raw materials and guaranteeing proper recycling of the principal …

In this paper, the partial replacement of volcanic pumice powder (VPP) was investigated for
use as a supplementary cementitious material. High-strength concrete (HSC) was prepared …

The replacement of Portland cement (PC) with either supplementary cementitious material
(SCM) or fillers, such as natural pozzolans (NP) or limestone powder (LP) respectively, is …

This is a study of the microstructure and chemical, mineralogical and structural composition
of the reaction products of supersulfated cements based on pumice (SSC-PM), prepared …

Concrete strength is dependent upon not only the water to cement ratio but also different
constituents of the concrete. The inclusion of natural zeolite (NZ) as an effective …
