Attenuation Law of Stress Waves in Cracked Rock Mass under Different Confining Pressures
Through theoretical analysis and indoor model tests, this paper explores the attenuation law of stress waves in the intact confined rock mass and cracked rock mass under different confining pressures, especially the relationship between the stress ...

Eksperimen Dan Analisis Lebar Retak Pada Balok Beton Bertulang Pasca Paparan Suhu Tinggi
Cracking is one of the structural behaviors reviewed under the service boundary conditions. Cracks will be the gaps in the various substances in the reinforced concrete structures that will make the structure vulnerable.

Self-healing cementitious materials by the combination of microfibres and superabsorbent polymers [PDF]
Concrete cracks due to its low tensile strength. The presence of cracks endangers the durability as they generate a pathway for harmful particles dissolved in fluids and gases. Without a proper treatment, maintenance costs will increase. Self-healing can

High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

EFFECT OF PRESTRESSED FORCE AND SIZE OF REINFORCEMENT ON CORROSION CRACK WIDTH IN CONCRETE MEMBER [PDF]
One of the main factors which terminate service life of concrete structure in corrosive environment is corrosion attack. Rust expansion of corroded reinforcement in concrete causes corrosion crack.

Correlating and predicting the air infiltration through the cracks of suspended timber floors [PDF]
This paper shows that the visible gap length may be used as a physical parameter when correlating pressure difference to volume flow rate (or air velocity) through the cracks between floorboards and can be termed the Equivalent Crack Length.
