“…The compressive strength increased slightly with the increase in PP fibre addition, which was unexpected owing to the principle that fibres improve tensile strength, but not compressive strength [96][97][98]. Oni et al [99] determined a slight increase for concrete with 0.3% PP fibre and a slight decrease with the addition of 0.4% of this fibre. For other tested types of polypropylene fibre, they obtained decrease in compressive The obtained cement-glass composite density was much lower than the density of plain concrete with granite aggregate (γ = 2205 ± 4 kg/m 3 ) and follows the demonstrated trend of the decrease in density with increasing glass fine aggregate [74].…”

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.

“…It was observed by Anike et al [20] that metal fiber-reinforced recycled aggregate concrete and metal fiber-reinforced blended aggregate concrete had 49% and 8.8% higher absorptions, respectively, compared to control concrete. Void content, which explains entrapped macroporosity, was reported to increase with the addition of fibers [21,22]. This was attributed to defects in the interfacial bond between fibers and the other components of Portland cement concrete resulting from the fiber addition [23].…”

Sustainable waste management is becoming more and more important in the construction industry due to increasing waste costs as well as environmental effects. As a result of increasing level of wastes and environmental damage, the use of these wastes has become the focus for beneficial construction activities and sustainable industrial applications. This study presents experimental results on the effect of industrial wastes on the performance of cementitious mixtures. The scope of this study, therefore, was to assess the effect of waste aluminium on physical and mechanical properties of cement based mixtures prepared in different compositions. Consistency, bulk density, porosity, absorption, flexural and compressive strength tests were carried out on mixtures produced by using waste aluminium aggregates in different percentages instead of fine aggregate. Results showed that mixtures prepared with 4% aluminium aggregates had the highest water absorption and porosity. With the addition of %1 lathe waste, it was observed that the flexural behavior of mortar was maximum and the optimum percentage for flexural strength was noted. In addition, when mixtures produced with the same percentage of aluminium were compared, the amount of binder played a significant role on both compressive and flexural strength. Results have shown that to incorporate aluminium into mixtures can be a suitable solution for recycling in industrial applications.

“…Enhanced porosity, which influences structural and functional properties of pervious concrete (23), leads to applications where the acoustic absorption or storm water runoff control is needed. To widen the application of this kind of concrete, researches are continuously working on the development of porous concrete with enhanced properties such as high performance pervious concrete (24)(25)(26) or fibre reinforced pervious concrete (27)(28)(29)(30)(31)(32). Zhong and Wille (33) analysed and discussed the influence of fibre reinforcement on the freeze-thaw durability of pervious concrete and concluded that the improvement can be achieved through the incorporation of fibres into high performance pervious concrete matrix.…”

“…As for the conventional concrete, the addition of fibres to pervious concrete can enhance its flexural strength. Oni et al (32) investigated pervious concrete pavement bricks reinforced with kevlar, polyvinyl alcohol and ultra-high molecular weight polyethylene fibres and achieved 9.5% increase of flexural strength in comparison to control mix that shows the effectiveness of fibres for pavement applications which are regularly subjected to two dimensional flexural stress. AlShareedah et al (34) investigated the potential of pervious concrete reinforced with fibres made of recycled cured carbon fibre composite material through a pervious concrete pavement demonstration project.…”

This paper deals with the possibility of the improvement of pervious concrete properties by incorporation of different types of fibres and studies the effect of short duration vibration of pervious concrete properties in comparison with compaction with wooden lath and hammer. Ten mixtures of pervious concrete were prepared, five of which were compacted with wooden lath and hammer and five by short duration vibration. Density, porosity, permeability and mechanical properties were tested for in hardened pervious concrete specimens. It was concluded that mixtures compacted by short duration vibration had better mechanical properties due to the formation of a viscous layer at the contact surface between the aggregate grain and the cement matrix during the compaction, as well as pore-related properties. The addition of fibres negatively affected porosity and permeability but generally improved mechanical properties of concrete. The positive effect of fibre addition was more emphasised in cases of vibrated mixtures.
