“…The behaviour of CH peaks is in agreement with the results of chemically determined free lime. Moreover, the XRD patterns act in a CaCO3 peak that increments with curing age, due to the increment of portlandite, which is accessible for carbonation with air CO2 (El-Didamony et al, 2020;Saraya, 2011;Diab et al, 2021).…”

The effect of pozzolanic material on the mechanical properties and microstructure of clinker Portland cement mortar was studied. The main objective of this research is to formulate a Pozzolanic blended cement mortar with high mechanical properties to reduce CO2 emissions and energy conservation uses in the clinker industry. The present investigation aims to study the effect of fresh basalt on the properties of clinker and Portland cement pastes. The rate of hydration was studied from the determination of free lime and combined water up to 90 days of hydration. The physicalmechanical properties such as compressive strength, phase composition, and microstructure of mortar were investigated. The results revealed that the water consistency increased with the basalt substance while the setting time was somewhat elongated. On the other hand, the combined water increases with the basalt content and curing time. This can be primarily due to the influence of nucleating of basalt as a filler in pozzolanic cement generation. The fresh mortar pastes were first cured at 100% relative humidity for 24 h and then cured in water for 90 days. The results showed that the compressive strength of the cement mortars with basalt pozzolanic mixed cement was higher than plain clinker Portland cement mortar; the improvement in compressive quality was 10% to 15% basalt.

“…Glass and basalt fibre reinforcing polymer meshes were compared by Diab et al [ 19 ] in their abilities to control alkali–silica reaction expansion and improve the mechanical characteristics of concrete affected by alkali–silica reaction. According to the findings, an increase in compressive strength was seen in the range of 4.6 to 39% for basalt fibre mesh and from 6.5 to 50% for glass fibre mesh.…”

Concrete is the most widely used and most affordable construction material. The structural damage that concrete cracks and fractures may cause can be severe. These concerns have lately been alleviated by new developments in fibre concretes. Recent advancements in fibrous concrete and its evolution have been rapidly drawing researchers’ attentions worldwide, which motivates the development of a new type of composite with superior impact resistance. Preplaced aggregate fibrous concrete (PAFC) is a revolutionary composite comprising a higher dosage of fibres. It has outstanding impact resistance that surpasses those of traditional fibrous concrete. The impact behaviour of PAFC in addition to glass fibre mesh (GFM) has not been investigated thoroughly. To fill this research gap, this study investigates the impact performance of three-layered PAFC comprising steel fibres and GFM insertion. Eight different mixtures were prepared and can be divided into two groups. In the first group, specimens were made with 4% fibres and two single, double and triple layers of GFM insertion between the three-layered concrete. The second group of specimens was reinforced with 5, 2 and 5% steel fibres at the top, middle and bottom layers, respectively. However, the GFM insertion scheme for the second group was the same as the first. Rectangular specimens of size 500 × 100 × 100 mm were cast and tested against drop weight impact. The parameters studied were cracking impact numbers, failure impact number, ductility index and failure patterns. In addition, an analytical model was used to evaluate the impact failure energies. Results indicate that the combined action of steel fibre and GFM exhibited an excellent impact resistance. Increasing the number of GFM insertions between the specimen layer led to increased impact strength. The dose of the fibres utilized in the outer layer of the PAFC was increased, resulting in the material having a higher impact resistance. The cracking impact numbers improved from 28 to 40%, and failure impact numbers ranged from 58.8 to 92.2% when the GFM insertion numbers increased from one to three.
