improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

As a building material, earth is known to be natural humidity regulator and improve comfort inside buildings, making it good choice for indoor plastering. The clayey phase ensures the sorption capacity of material its global cohesion by acting as binder sand grain skeleton. However, clay also induces drying shrinkage mortar, leading cracking plaster. Additives or stabilizers are typically used ...

This paper addresses issues related to cracking and blisters in deposited films encountered a lift-off process with electron beam evaporation bilayer PMMA resist system. The impact of charged particles, i.e. electrons ions, is investigated using an chamber equipped ring-magnets plate electrode placed front the sample. By replacing hollow cylinder, modified setup utilizing passive components all...

Database cracking has been an area of active research in recent years. The core idea of database cracking is to create indexes adaptively and incrementally as a side-product of query processing. Several works have proposed different cracking techniques for different aspects including updates, tuple-reconstruction, convergence, concurrency-control, and robustness. However, there is a lack of any...

This work investigates the equilibrium stage of crack propagation a fine-grained soil after several drying and wetting cycles (shrinkage swelling hysteresis). is found to be crucial in practical engineering since continues show its irreversible hydraulic settlement, which potential risk for some severe structural damages. The shrinkage area were determined by using image processing method. For ...

Humidity change in concrete is the leading cause of shrinkage. Moreover, moisture diffusion coefficient an essential parameter for assessing and predicting internal content concrete. However, there a lack theoretical construction experimental studies on effect different conditions, especially constraints, Therefore, humidity, pore structure parameters, basic mechanical properties under strength...

Autogenous shrinkage is related to the chemistry and changes in internal structure of cement concrete paste on drying. This problem drying early stages that occur without any moisture transfer surrounding environment has triggered incorporation fibres matrix fill micropores control cracking (autogenous shrinkage). study aimed at investigating potential use Urena lobata (UL) fibre as microreinfo...

Asphalt is a kind of temperature-sensitive material. With the decrease temperature, deformation capacity an asphalt mixture will be significantly reduced. When temperature greatly reduced, layer produce large shrinkage tensile stress and strain, resulting in cracking. Therefore, cracking resistance behavior essential for asphalt. In order to study geosynthetics-reinforced under lower temperatur...

This paper is devoted to numerical modelling of cracking in concrete-like materials by explicitly taking into account microscopic heterogeneities. A method based on peridynamics theory proposed. The formulation and implementation the are first presented. Its efficiency initiation propagation multiple cracks heterogeneous then demonstrated. proposed further applied description process induced dr...
