Impact of Wetting–Drying Cycles on the Mechanical Properties and Microstructure of Wood Waste–Gypsum Composites [PDF]

open access: yes, 2019
Large amounts of wood waste are generated each year in the world. In an attempt to identify a good recovery option for those residues, wood waste from construction and demolition works were used as raw materials in gypsum plasters.

Using the plate-creep test to determine the impact strength properties of concrete

open access: yesJournal of Engineering Research, 2022
The paper aims to design a concrete against repetitive impact and abrasion resistance. Macro/micro steel fibers and two types of crushed stone based on limestone and corundum as aggregate were used in concrete mixtures. Impact test device has been modified, designed and used for impact strength testing of concrete. The usability of the plate creep test

DEFORMATION-STRENGTH MODEL APPLICATION AT THE DETERMINING OF STRESS-STRAIN STATE OF REINFORCED CONCRETE STRUCTURES

open access: yesOdes’kyi Politechnichnyi Universytet. Pratsi, 2017
The work considers the possibility and expediency of deformation-strength model applica-tion in the study of stress-strain state of reinforced concrete structures. Relying on the basic provisions of the mechanics of solid deformable body and the real stages of work of reinforced concrete elements, it is generalized and established by the authors that ...
