“…It was assessed that concrete made with WMP has a higher resistance to sulphate attack and freezing and thawing than conventional concrete without WMP. The previous result was confirmed by another study [ 19 ], where it was stated that concrete made with 10% WMP showed higher durability than reference concrete made without WMP. Finally, during an extensive review paper [ 23 ], it was emphasized that the mechanical and physical properties of concrete produced by using WMP as a partial replacement of cement by weight were enhanced and that the cost of construction was decreased.…”

“…Subsequently, when these stones are prepared for use by processing, sawing, and shaping them, a huge amount of powder waste is produced, which causes a global environmental problem. Therefore, the recycling of waste marble powder (WMP) in the building sector for the manufacture of sustainable concrete as a replacement for cement has been the subject of several studies in the past decade [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. This trend of studies has grown to minimize final construction costs, since WMP is very cheap and could be available for free, as well as to reduce global pollution.…”

Currently, the costs of building materials, especially cement, are increasing. Waste marble powder (WMP) could be used as a cement replacement material to produce environmentally friendly concrete to help preserve resources and reduce environmental pollution. The study’s goals are (1) to evaluate the effects of using marble powder in place of cement in high-strength concrete (HSC) on the material’s mechanical properties and durability characteristics. (2) The study is expanded to assess the effect of using partial WMP on the shear behavior of HSC beams under static loads. Eight half-scale simply supported reinforced beams with and without WMP have been tested. Each beam’s cross-section was 120 × 200 mm, and each beam had a total length of 1000 mm. The ratios of the used WMP were 0%, 2.5%, 5%, 7.5% by weight, and two different stirrup ratios, 0% and 0.47%, were used. When applied to HSC beams with and without WMP, the shear strength provisions of two of the most used codes, such as the locally used Egyptian Code (ECP 207) and the internationally used American Concrete Institute’s (ACI-2019), were examined. Using the ABAQUS software, the experimental results were compared to the findings of the nonlinear finite element analysis. The results established that partial replacement of cement by WMP led to increases in the concrete’s compressive and tensile strengths of about 15% and 16%, respectively. When tested specimens were exposed to acid attack, there were slight losses in weight and compressive strength (1.25% to 2.47%) for both with and without the addition of WMP. Both the concrete with and without WMP showed the same level of water absorption. Additionally, WMP led to an enhancement in the shear capacities for all beams. Increasing the WMP ratio from 0% to 2.5%, 5%, and 7.5% increased the shear capacity by about 13%, 20%, and 28%, respectively, for beams without stirrups, while for beams with stirrups, the shear capacity improved by 12%, 19%, and 25%, respectively. The enhancement in the beams’ shear capacities could be attributed to the advanced concrete matrix produced by WMP’s extremely small particle size.

“…Traditional rotary‐calcined metakaolins tend to be angular layered particles, whereas flash metakaolins contain spherical particles. It has various advantages, such as in constructions of bridges, water retaining structures, high rise buildings, offshore structures, mass concreting, and nuclear power stations 99–102 . On an industrial scale, most metakaolins are obtained from a three‐stage method that comprises a selection/grinding process, then calcination of raw Kaol for several hours in a rotary kiln, followed by grinding of the burned material.…”

The present study is focused on the compressive strength, water retention, and workability by varying the percentage of poly ethylene glycol 200 and liquid paraffin wax from 0% to 1% by weight of cement for self‐compacting concrete and compares it with conventional SCC. Percentages of 0.1%, 0.5%, and 1% (in proportion to the weight of cement) were adopted in the study. The comparison was done in a grade concrete and with cases such as indoor curing and water‐based curing. Slump‐flow test and V‐funnel tests were carried out on the fresh concrete to evaluate the workability of concrete. Concrete weight loss with time is evaluated to determine the water retention capacity. Compressive strength of cube specimens was conducted at the end of 7 and 28 days of curing. The durability of the concrete was assessed by immersing the concrete specimens in acids. The fresh properties were satisfied according to EFNARC specifications. Based on the weight loss percentage and satisfaction of compressive strength, the dosage of a self‐curing compound was determined. XRD analysis of the concrete was also performed on the concrete specimens.

“…On the other hand, ultrafine materials due to their small particle size may increase the chemical reactivity with the cement compounds to create carbonate salts into the pores (Chousidis et al, 2016b). In the literature (Choudhary et al, 2021), (Seleem et al, 2020), it has been also investigated the beneficial effect of ultrafine materials on the pitting corrosion of steel rebars exposed to chloride ions. The experimental results showed that the time to the initiation of reinforcement corrosion in specimens with 8% wt.…”

This work is an extensive experimental study on the corrosion behavior of reinforced cementitious mortars containing industrial byproducts and waste materials. In particular, calcareous (C-class) fly ashes, iron mill scale and Electrolytic Manganese Dioxide (E.M.D.) waste were used as additives in mortars production. The abovementioned materials were used without any prior treatment or management and replaced the cement in concrete mixing by 10% wt. of cement weight. For the experimental set-up, reinforced mortars were prepared and exposed to coastal area for 12 months, while some of them were remained in a salt spray cabin for 60 days. The corrosion monitoring was performed by electrochemical and mass loss measurements, while chloride content, porosity, carbonation and mineralogy of mortars were also estimated. The results indicate, that there is a development in durability and chloride penetration resistance of composites comparing with the conventional mortars at late ages. At the same time, it was also observed that their chemical composition and fineness, control the diffusion of CO2 into the pore system and lead to increased carbonation of composite mortars. The challenge of this work is the production of eco-friendly composites with high chloride and carbon dioxide penetration resistance.
