..., significantly improve the concrete’s performance. Individually, SCF and PPF increased compressive strength by 7–17% at 1% fibre content, beyond which strength declined due to fibre clumping. The optimal hybrid mix ( SCF 0.75% + PPF 0.75%) achieved the highest strength. Tensile and flexural strengths...

... and lowering the adobes’ compressive strength. To overcome the limitations arising from variations in plant fibre density, this study evaluates the role of plant fibre addition on the compressive strengths of adobes in terms of per cent volume fraction (v_f). Analysis of data from...

... of 9.37 GHz, which are ≈54% and 206% higher than those of pure cement mortar specimens respectively. Meanwhile, it maintains a compressive strength similar to that of pure cement mortar, providing a new solution for sustainable and functional building materials. Corresponding author Xinghui Yao...

... delayed and intensified with higher SP content, leading to marginal setting delays. At 2 h, compressive strength increased to 8.95 MPa with 1 wt% SP . While early-age strength (1 and 3 days) was slightly delayed due to retarded silicate hydration, all mixes showed comparable strength at 28 days...

Wollastonite also contains an amorphous silica phase and polymorphic forms of calcium carbonate, which contribute to enhanced hydration when combined with Portland cement. This study examined the effect...
