“…Glass cullet may be used as a replacement for cement or aggregate [ 45 , 46 , 47 , 48 ], while he pozzolanic reactivity of glass powder with particle size below 100 μm is observed as an increase in compressive strength [ 49 , 50 , 51 ]. The impact of glass powder as a cement replacement on concrete or geopolymer properties was presented in [ 52 , 53 , 54 , 55 , 56 ]. For example, Federico and Chidiac [ 57 ] analysed the kinetic and performance properties of cementitious mixes with glass powder.…”

In accordance with the principles of sustainable development, environmentally friendly, low-emission, and energy-intensive materials and technologies, as well as waste management, should be used. Concrete production is responsible for significant energy consumption and CO2 production; therefore, it is necessary to look for new solutions in which components are replaced by other materials, preferably recycled. A positive way is to use glass waste. In order to determine the effect of a significant glass cullet content on the properties of concrete, glass powder was used as a filler and 100% glass aggregate. The cement–glass composite has low tensile strength and brittle failure. In order to improve tensile strength, the effects of adding polypropylene fibres on the mechanical properties of the composite were investigated. With the addition of 300, 600, 900, 1200, and 1500 g/m3 of fibres, which corresponds to 0.0625%, 0.1250%, 0.1875%, 0.2500%, and 0.3125% of cement mass, respectively, flexural strength increased compared with the base sample by 4.1%, 8.2%, 14.3%, 20.4%, and 26.5%, respectively, while the increase in splitting strength was 35%, 45%, 115%, 135%, and 185%, respectively. Moreover, with the addition of fibres, a decrease in slump by 25.9%, 39.7%, 48.3%, 56.9%, and 65.5%, respectively, compared with the reference specimen was determined.

“…Therefore, there is a need to look for materials as a replacement for cement or aggregate. Recycled materials are used to limited energy consumption by the concrete industry and the production of concrete as an environmentally friendly material [ 7 , 8 , 9 , 10 ]. The use of fly ash as a replacement for cement was studied by many researchers [ 11 , 12 , 13 , 14 , 15 ].…”

Effect of Waste Glass Addition as a Replacement for Fine Aggregate on Properties of Mortar

et al. 2020

A responsible approach towards sustainable development requires the use of environmentally friendly, low-carbon, and energy-intensive materials. One positive way is to use glass waste as a replacement for fine natural aggregate. For this purpose, the effects of adding glass cullet to the mechanical properties of mortar were carried out. The glass aggregate made from recycled post-consumer waste glass (food, medicine, and cosmetics packaging, including mostly bottles), were used. This experimental work included four different contents of fine glass cullet (5, 10, 15, and 20 wt.% of fine aggregate). The compressive, flexural, and split tensile strengths were evaluated. Moreover, the modulus of elasticity and Poisson coefficient were determined. The addition of glass sand aggregate increases the mechanical properties of mortar. When comparing the strength, the obtained improvement in split tensile strength was the least affected. The obtained effect for the increased analysed properties of the glass sand aggregate content has been rarely reported. Moreover, it was determined that by increasing the recycled glass sand aggregate content, the density of mortar decreased. In addition, the relationships between the properties for mortar containing glass sand aggregate were observed.

“…A constant packing density in the powder phase for flowing mortars could be estimated using the flow ability of the mortar. 37 Therefore, the mortar flow cone recommended by ASTM C230 38 was used to control a constant slump-flow which was compelled to be equal to 130 mm (control mix design).…”

In this paper, the relationship between mechanical strength and void characteristics including porosity, the mean area of voids (MAV), and circularity was determined for the first time by analyzing the petrographic images of some cement mortars containing multi-walled carbon nanotubes (MWCNTs). The results showed that the compressive, tensile, and flexural strength for specimens containing 0.1% MWCNTs (optimum dosage of MWCNT) were 21, 12.5, and 9.5% more than that of the control samples, respectively. Also, it was shown that the application of MWCNTs can change the shape and the amount of voids, thereby imposing a significant impact on the mortar behavior. For the optimum dosage of MWCNTs, the porosity and MAV decreased about 63 and 71%, respectively, while the circularity enhanced 23% in comparison with the ordinary mortar samples. The void shape is one of the reasons for the enhanced properties of the MWCNT mortars. The image processing of the petrographic specimens and probability theorization revealed that the circularity of the voids had a significant impact on the flexural strength of the mortars, while the compressive strength was mostly affected by only the amount of porosity.
