Comparative analysis of the compressive strength of concrete under different curing methods

open access: yesIOP Conference Series: Materials Science and Engineering, 2021
Concrete is the most widely used material in construction, which possesses different characteristics and possible manufacturing methods. Concrete is, also, characterized by its high resistance to compression and durability, factors that could have been ...

Evaluation of in-situ shrinkage and expansion properties of polymer composite materials for adhesive anchor systems by a novel approach based on digital image correlation [PDF]

open access: yes, 2019
The curing reaction of thermosetting resins is associated with chemical shrinkage which is overlapped with thermal expansion as a result of the exothermal enthalpy. Final material properties of the polymer are determined by this critical process.

The effects of using magnetized water in reactive powder concrete with different curing methods

open access: yes, 2021
The effects of using magnetized water in reactive powder concrete (RPC) under various curing procedures was investigated. The RPC samples were separated into four groups, cured with three different curing methods compared to normal curing (lab conditions)

Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers [PDF]

open access: yes, 2018
Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical ...

Latent curing of epoxy-thiol thermosets [PDF]

open access: yes, 2017
Epoxy-thiol curing is a click reaction which allows quantitative yield of the end products. The base-catalyzed reaction is rapid at low temperatures so it is most often desirable to harness reactivity by using latent catalysts.

Tensile Response of Adhesively Bonded Composite-to-composite Single-lap Joints in the Presence of Bond Deficiency [PDF]

open access: yes, 2017
This paper studies the quasi-static tensile response of adhesively bonded composite-to-composite single-lap joints in the presence of weak and kissing bonds, as an attempt for characterisation of bond deficiencies likely to occur in polymer composite ...

On the path to a new generation of cement-based composites through the use of lignocellulosic micro/nanofibers [PDF]

open access: yes, 2019
Due to its high biocompatibility, bio-degradability, and low cost, cellulose finds application in disparate areas of research. Here we focus our attention on the potential applications of cellulose nanofiber in cement-basedmaterials for the building ...
