Abstract: Sulfate plays a critical role in portland cement. The internal gypsum (CaSO4·2H2O) incorporating with clinker controls the hydration of cement, while the external gypsum can attack the hydration products. Magnesium sulfate ...

Abstract: The dynamic compaction (DC) method is a versatile ground treatment technique with growing popularity. It is applicable to a wide variety of soil types and conditions, particularly sandy materials and granular fills. This ...

Abstract: Although soil–rock mixtures (S-RMs) exist extensively on Earth’s surface, their mechanical behaviors remain elusive. In this study, a series of large-scale direct-shear tests was conducted to investigate the mechanical ...

Abstract: This study investigated the effect of alkalis on C3S hydration with and without incorporating aluminate phases. Pastes of 100% C3S and 90% C3S+10% metakaolin (MK) were prepared at 1%, 2%, and 3% Na2O content. X-ray diffraction ...

Abstract: Cracking of concrete structures during hydration often occurs during construction. This study investigated the expansive property of concrete with an unstrained expansive agent to reduce cracking. Laboratory tests, field ...
