Performance of two‐to‐one non‐contact post‐installed lap splices

Structural Concrete, EarlyView.
Abstract Post‐installed lap splices ensure the continuity of steel reinforcement in concrete‐to‐concrete connections by overlapping cast‐in (CI) reinforcing bars (rebars) with post‐installed (PI) rebars. Typically, the design of such splices follows provisions originally intended for CI lap splices, despite the differences in execution and bond ...

Clays for Low‐Carbon Cements: Overview, Progress, and Challenges

Global Challenges, Volume 10, Issue 1, January 2026.
This review provides a critical overview of recent developments of activated clays to function as artificial pozzolans. After a thorough description of the clays that yield good pozzolanic performances, selected examples are given on thermal and mechanical activations. Chiefly, general correlations are extracted from reported data despite its scattered
