Abstract Saline soil in Northwest China is susceptible to frequent and severe freeze–thaw
cycles (FTC), resulting in railway and pavement disasters, emphasizing the need for …

Foam lightweight soil is used frequently in engineering construction for soft soil areas due to
its superior lightness and economy, but its greater cement usage will result in cost increase …

A novel technique involves the preparation of foamed concrete utilizing MgO as a substitute
for Portland cement (PC) and CO 2 foam in place of air foam. This technique is referred to as …

Mixing foamed lightweight soil (FLS) with marine sand (MS) can be a sustainable approach
for maximizing waste resources, although the fundamental properties (the physical …

Red mud (RM) is a kind of alkaline waste produced by the extraction of alumina from
bauxite. According to statistics, approximately 1.5 billion tons of RM are produced worldwide …

A universal testing machine and a 50 mm split Hopkinson pressure bar (SHPB) were used to
conduct salt erosion and freeze-thaw (FT) cycle coupling tests on cement soil specimens …

Tailings can be used as embankment materials instead of sand. However, they contain large
amounts of heavy metal pollutants, which can lead to groundwater pollution. In this …

The use of soil tuff, an industrial solid waste, for the modification of lead–zinc tailings as
subgrade fillers presents a sustainable solution for concurrently addressing the negative …

This paper proposes an innovative preparation measure for magnesium oxide (MgO)-based
foamed concrete. Carbon dioxide (CO 2) foam has been introduced into the sample as a …
