“…About 3% increase in compressive strength of samples with 1.0% by weight of glass fibers (mixed length 6–12–18 mm, diameter 14 μm, and tensile strength >1.7 GPa) was achieved by Ali et al [ 44 ]. For different type of glass fibers, Atewi [ 45 ], after 28 days, obtained compressive strength equal to around 74.2 MPa, using glass fibers with length 12 mm, diameter 13 μm, and tensile strength 3.4 GPa, which is around 3% increase as well (compared to non-modified samples with compressive strength equal 71.8 MPa).…”

The progressive increase in the amount of glass waste produced each year in the world made it necessary to start the search for new recycling methods. This work summarizes the experimental results of the study on mortar samples containing dispersed reinforcement in the form of glass fibers, fully made from melted glass waste (bottles). Mortar mixes were prepared according to a new, laboratory-calculated recipe containing glass fibers, granite as aggregate, polycarboxylate-based deflocculant and Portland cement (52.5 MPa). This experimental work involved three different contents (600, 1200, and 1800 g/m3) of recycled glass fibers. After 28 days, the mechanical properties such as compressive, flexural, and split tensile strength were characterized. Furthermore, the modulus of elasticity and Poisson coefficient were determined. The initial and final setting times, porosity, and pH of the blends were measured. Images of optical microscopy (OM) were taken. The addition of glass fibers improves the properties of mortar. The highest values of mechanical properties were obtained for concrete with the addition of 1800 g/m3 of glass fibers (31.5% increase in compressive strength, 29.9% increase in flexural strength, and 97.6% increase in split tensile strength compared to base sample).

“…By visual inspection, crack growth was under the notch of 30 mm at a depth of 75 mm and over a width of 150 mm, selected as a region of interest (ROI). Hence an ROI 75 × 30 × 150 mm 3 was considered for analysis, to quantify the total number of steel fiber and CA participating in the failure region during the WST. Under the ROI, SCC-A specimen had 49 CA particles before WST, while SCC-AF had 41 CA and 139 hooked end steel fibers, dispersed across the depth of the specimen.…”

“…to enhance mechanical properties and durability. SCC mixes have higher finer particle concentrations, resulting in a highly workable and rich interfacial transition zone (ITZ) interface in harder concrete, relative to conventional concrete [2][3][4]. Failure mechanisms taking place in concrete are often influenced by the material properties and their proportions adopted during the mix design [5][6][7][8], for which SCC is no exception.…”

Wedge splitting test gained popularity as a stable and simple method to predict the fracture mechanism properties of concrete specimens. The present research focuses on understanding the behavior of self-compacting concrete specimens made with and without steel fibers tested using wedge splitting test, later scanned under high resolution computed tomography. The contribution of hooked end steel fiber and coarse aggregates in fiber reinforced specimens was compared without steel fiber reinforced concrete specimens using high resolution computed tomography. As fracture takes place across the plane perpendicular to the splitting force, i.e. along the depth of specimens. High resolution computed tomography technique was adopted in visualizing the changes taking place across the matrix, coarse aggregate and steel fibers, along with the specimen's depth. Datasets of the images, obtained from computed tomography, after images analysis and volume reconstruction, revealed a higher coarse aggregate and steel fiber participation in the failure region of without and with fibers specimens. Computed tomography investigation indicated a total of 23 coarse aggregate and 64 steel fibers participated in resisting the failure, during wedge splitting test of without and with fibers specimens. Therefore, high resolution computed tomography can be used in understanding, quantifying the participation of coarse aggregate and steel fiber in the failure plane, under fracture loads.

Potential Effect of Surface Modified Nano‐SiO₂ with PDDA on the Cement Paste Early Hydration

et al. 2020

View full text Add to dashboard Cite

The potential application of surface modified nano‐SiO2 (NS) particles with poly (dimethyl diallyl ammonium chloride) (PDDA) has been reported in other fields, but not in civil construction. This paper aims to assess the influence of surface modified NS with PDDA on the early‐age hydration of cement paste, where cement is replaced by 0.3%, 1% and 3% of NS particle. PDDA can be introduced onto the surface of NS via long‐distance charge pairs. Calorimetric measurements of cement pastes with 0.35 w/b (water/binder) ratio show that NS particles accelerate the cement hydration, while PDDA retards it. Moreover, the cement hydration is controlled by PDDA at lower dosage of NS/PDDA particle, which delays the exothermic peaks of cement hydration, while the cement hydration is controlled by NS particle aggregates at higher dosage of NS/PDDA particle. Based on the results above, the mechanism of the adsorption of NS/PDDA particle on cement particle surfaces is proposed.
