Strength grading and selected strength properties of European hardwoods [PDF]

open access: yes, 2022
Die Laubholzvorräte werden in Mitteleuropa in Zukunft ansteigen und es ist erklärter politischer Wille, diese Ressourcen im Bauwesen stofflich zu nutzen. Seit der Jahrtausendwende wurden deshalb mehr und mehr öffentliche Mittel für die Laubholzforschung zur Verfügung gestellt.

Modeling the corrosion initiation time of slag concrete using the artificial neural network

open access: yesHBRC Journal, 2014
This paper focuses on the Artificial Neural Network (ANN) as an alternative approach to simulate the corrosion initiation time of slag concrete obtained from the error function solution to Fick’s second law of diffusion.

Developing an artificial neural network model to evaluate chloride diffusivity in high performance concrete

open access: yesHBRC Journal, 2013
Chloride attack is one of the major causes of deterioration of reinforced concrete structures. In order to evaluate chloride behavior in concrete, a reasonable prediction for the diffusion coefficient of chloride ion (Dc), which governs the mechanism of ...

An Experimental and Numerical Study of Diorite-Porphyrites With Different Weathered Degree in the Direct Shear Test

open access: yesFrontiers in Earth Science, 2020
There are many well-developed weathered diorite-porphyrites, except main rocks, in the Jurong pumped storage power station of Jiangsu Province, China. Due to different geological environments, diorite-porphyrites emerged by invading faults and can alter ...

Study on some of the strength properties of soft clay stabilized with plastic waste strips [PDF]

open access: yesArchives of Civil Engineering, 2022
It is well known that if plastic wastes are not well managed, it has a negative impact on the environment as well as on human health. In this study, recycling plastic waste in form of strips for stabilizing weak subgrade soil is proposed.

Mechanical Properties of Frozen Glacial Tills due to Short Periods of Thawing

open access: yesFrontiers in Earth Science, 2021
Due to the warming climate, glacier retreat has left massive glacial tills in steep gullies; ice in the soil is prone to change phase resulting in the decrease of the ice strength and bonding of soil particles; collapse of thawing tills can lead to ...

Triaxial Compression Testing of Multicomponent Geomaterials from Quartz-Poor (Syenitic) Systems

open access: yesGeoScience Engineering, 2017
This paper focuses on mafic microgranular enclaves enclosed in quartz-poor igneous rocks and their effect on strength properties of the rock massif. The study examines host rock–enclave multicomponent geomaterials from enclave-bearing syenitic rocks from

The Use of Mg(OH)2 in the Final Peroxide Bleaching Stage of Wheat Straw Pulp

open access: yesBioResources, 2013
Magnesium-based alkali is an attractive alkaline source for the peroxide bleaching of high-yield pulp. However, little information is available on Mg(OH)2 application in the final peroxide bleaching stage of wheat straw pulp.
