“…Ahmed [93] studied the use of EN-Al as a cement substitute in concrete and found that M-Water improved the strength (13%) and reduced the capillary porosity (27%) for specimens with 1% EN-Al. The properties of concrete with VA and M-Water were evaluated by Keshta et al [94]. M-Water improved the workability and increased the fc by 43% at 7 days and 36% at 28 days without VA and by 22% at 7 days and 33% at 28 days with 5% VA.…”

“…When 0, 1, 2, or 3% of EN-Al replacement levels were used, there was an increase of about 8, 12, or 16% in the 28-day fc of specimens made with M-Water compared to specimens made with tap water.

The wide use of multi-component cement of highly reduced Portland clinker factor is largely impeded by detrimental changes in the rheological properties of concrete mixes, a substantial reduction in the early rate of cement hardening, and sometimes the insufficient strength of mature concrete. Therefore, major changes are needed in traditional concrete-production technologies if low-clinker cement is to gain wider acceptance. This review’s goal is to summarize the impacts of using non-ionizing radiation methods to improve the dispersion of concrete mix constituents, cement setting, and early hardening. The potential impacts of such interactions on the permeability and strength of concrete are also highlighted and investigated. Their intriguing potential for delivering additional energy to cementitious mixtures is analyzed for batch water, solid non-clinker constituents of cement (mainly supplementary cementitious materials), and their mixtures with aggregates. The advantages of adopting these non-traditional methods are found to be highly alluring to the greener preparation techniques used in the construction materials sector.

“…Meanwhile, the definition of sustainable concrete is "concrete that consumes much less energy during production and emits significantly less carbon dioxide" [30,31]. To achieve this goal and expand the usage of self-curing green concrete, also known as sustainable self-curing concrete (SSC), numerous studies focused on incorporating waste and byproducts in concrete [32][33][34]. Crushed ceramic (CC) as a construction waste was used to produce SSC.…”

“…The VP, CC, and PEG were prepared to enhance the characteristics of the developed SSC based on previous studies and standard codes, using VP at replacement percentages of 0%, 5%, 10%, 15%, and 20% of cement weight; CC at percentages of 0 and 50%; and PEG at percentages of 0%, 1%, 1.5%, and 2%. The replacements of VP, CC, and PEG were selected according to previous studies [32,52,53]. This study presents the utilization of various waste materials in concrete, the resulting characteristic strength attained thereby, and limitations in the utilization of those materials, especially the use of VP, as this is the first time it has been used in self-curing concrete.…”

This study investigates the properties of sustainable self-curing concrete (SSC) by adding volcanic powder (VP), crushed ceramic (CC), and polyethylene glycol 6000 (PEG). VP and CC are prepared from volcanic ash, as a natural pozzolanic material, and construction waste, respectively. PEG is used as an inner-curing agent. Twenty-six concrete mixtures are prepared using VP at 5%, 10%, 15%, and 20%, CC at 50%, and PEG at 1%, 1.5%, and 2% and tested after 7, 28, and 56 days. Mechanical, workability, and durability characteristics are evaluated using different tests. The bond and cohesion between aggregates and mortar are tested using a scanning electron microscope (SEM). The results show that the optimum replacement mix for enhancing strengths, by producing C-S-H, of the studied SSC is 10% VP and 1.5% PEG. This improved the compressive, tensile, and flexural strengths of SSC by 54.5%, 60.7%, and 34.9%, respectively, compared to a reference mix. Adding CC enhances the compressive strength of SSC by 41.6% and 11.5% and decreases chloride penetration by 10% and 9.1% compared to control mixes. PEG improves the mechanical, workability, and durability characteristics of SSC even with the addition of 1%. The obtained results reveal the possibility of using VP and CC in producing SSC.

“…In recent decades, a wide variety of industrial wastes, including marble dust, coal, rice husk ash, phospho gypsum, dust from cement kilns, copper slag, slag from blast furnaces, bagasse ash, ceramic dust, waste steel chips, and brick dust, have been successfully to use as stabilizing agents, regardless of the addition of a tiny proportion of cementing agent like a binder, to improve end up wasting management and utilization. [2][3] When it comes to designing, building, and maintaining physical structures, civil engineering is one of the most important and rapidly developing subdisciplines of engineering. The construction business is expanding fast, necessitating green building materials that are both long-lasting and environmentally benign.…”

Hazardous Jarosite Waste's Potential for use as a Construction Material in Civil Engineering

The rate of industrialization is a good indicator of a country's progress. Large quantities of trash and by-products are produced as a result of several operations, including those that are industrial, mining, municipal, agricultural, and many others. In addition, these materials are being explored for potential use as filler in embankment design, as well as sub-base or base layers in road building. Use of potentially dangerous jarosite waste mixed with steel industry waste is advocated in the present research.
