... saline water, on the compressive strength of soil–cement mixtures with 10% and 30% by weight cement content and cured for 7, 28, and 90 days. The results show that soil cement with highly saline water significantly enhances early-age strength, achieving the highest unconfined compressive strength...

... strength, rebound rate and microstructures. Plastic aggregate reduces slump, yet optimal PAM dosage enhances cement paste cohesion and uniform plastic particle distribution. While higher plastic content lowers compressive strength, PAM mitigates this by densifying the interfacial transition zone...

..., the effects of biochar content on MICP reinforcement effect were discussed by using calcareous sand with different particle sizes (0.25 mm, 0.5 mm, and 1 mm). The role of biochar in improving cementation uniformity and calcium carbonate deposition distribution was revealed by unconfined compressive strength...

... the evolution of unconfined compressive strength (q_u) and microstructural alterations in cement-stabilised silt under varying pore-water salinities (S₀ = 0%–4%) and curing temperatures (5°C, 25°C, 45°C). Mercury intrusion porosimetry revealed that increasing salinity from...

... ), mineral slag ( MS ), two desulfurisation by-products (DP-1 and DP-2), and a reduced amount of OPC . The optimal composition, determined by way of response surface methodology, was MS:SS:DP-1:DP-2:OPC = 40:20:15:5:20. The SWB-stabilised silt achieved unconfined compressive strengths ( UCS ) of 1.99 MPa...

... soil. Under this condition, the soil samples’ unconfined compressive strength, shear strength, and calcium carbonate (CaCO₃) generation reached the highest values. Moreover, its fracture development was also significantly improved. Microanalysis showed that calcium carbonate crystals...

... samples were evaluated for unconfined compressive strength (UCS) and indirect tensile strength using a custom-designed measurement facility considering the number of freeze–thaw (F-T) cycles, loading rates, and curing duration. The double-punch test is shown to be effective in capturing samples’ brittle...

... in temperature, the uniaxial compressive strength (UCS) and porosity of both dry and saturated granite monotonically increase, while the elastic modulus undergoes an increase–decrease transition and finally stabilises. At the same temperature, the UCS and elastic modulus of dry granite are generally greater than...

...-activated mortar targeting pavement applications was explored. As BR and PG alone proved to be ineffectual in developing geopolymer/alkali-activated mortar because of undesirably low compressive strength, the challenge lies in synthesis of alkali-activated mortar with high strength using a combination...

... comparable, confirming their engineering viability without modifications. Mound soils exhibited a twofold increase in unconfined compressive strength and a 33.9% increment in California Bearing Ratio strength. One-way analysis of variance tests confirmed these differences with p-value ranges...

... compressive strength (UCS), hydraulic conductivity (k) and leachate characteristics tests. As the GGBS percentage in the mix blend increased, the LL, FSI, optimum moisture content, k determined with deionised water/diesel oil contaminants and leachate concentration decreased, whereas...
