“…The various studies were carried out by the researchers to improve the strength parameters by using traditional herbs (Gallnut & Jaggery). In the contemporary world, Eco-friendly construction material is becoming famous due to the fact that they do not affect the earth and the environment [19]. Eco-friendly construction is very essential in the future because much of the other resources are getting used up.…”

The contemporary building material despite the significance of cement in construction industry is the lime mortars because of its usage as a structural repair material around the ancient heritage structures. Though the significance of lime mortars lies in the fact of compatibility towards the existing ancient lime-based structures, the method of construction and material preparations are still undisclosed. In such a case, it is necessary for the researchers to analyze scientifically, the influences of various additives towards the performance of lime mortars. This paper tries to attempt two natural additives viz., gallnut (Terminalia chebula) and palm jaggery (Saccharam officinarum) as modifiers of mixing water in the preparation of class B hydraulic lime-based mortars through the process of fermentation. Based upon the trials, 39 mixes were considered with varying water to lime ratios and dosages of additives. Experimental tests such as workability, compressive strength, water absorption, acid resistance and NaCl cyclic tests were conducted along with SEM and XRD microstructural assessments. The maximum compressive strength achieved was about 4.3 MPa which is 200% that of conventional lime mortars. Jaggery and gallnut-based additives were efficient in various durability studies however the performance of jaggery is superior to gallnut in various aspects.

“…Using bioconcrete in constructions and maintenance of old structures will contribute to preserve structure of the concrete, and reducing overall costs (Harshali et al 2016;Alves et al 2019;Castro-Alonso et al 2019). Additionally, microbe's contributions in this field are to be added to the list of biotechnological applications that emphasis the ability of microbes to continuously serve humanity (Daba et al 2018;Elkhateeb and Daba 2019;Waghmode et al 2019;Algaifi et al 2020). The term "microbe" refers to many different types of organisms, but research work on self-healing concrete has been so far restricted to bacteria (Achal et al 2011;Krishnapriya and Babu 2015;Jin et al 2018;Ruan et al 2019).…”

Abstract. Elkhateeb WA, Elnahas MO, Daba GM. 2021. Review: Microbial induced mineralization of calcium carbonate for self-Healing concrete. Asian J Nat Prod Biochem 19: 1-9. Low-cost solutions achieving concrete self-healing are attracting researchers attention. Generally, concrete self-healing mechanism has been so far accomplished by three approaches: autogenous healing, encapsulation of polymeric material, and microbial induced mineralization of calcium carbonate. Microbial approach seems like an attractive potent, relatively cheap way to achieve concrete self-healing. Hence, this review elucidates the microbial concrete self-healing mechanisms, and compare the roles of fungal and bacterial mediated self-healing concrete.

“…Today more and more people are interested in factors aiming at making construction materials more eco-friendly, as written by Waghmode et. al [1]. Cementitious composites are the most widely used materials in the industry and so there is no surprise many efforts have been undertaken in researches for minimizing their impacts to the environment, described by Wang & Li [2].…”

This paper focuses on mortar in which cement is partially replaced with siliceous fly ash and granite powder and subjected to abrasion. To optimise the process of testing abrasion resistance, artificial neural network (ANN) was proposed to predict results. Predicting abrasion resistance of mortar, especially with addition of wastes is not widely explored and requires greater academic attention. The possibility of applying machine learning is reducing amount of destructive tests methods in favour of prediction, therefore sustainable approach. This study confirms that it is possible to create eco-friendly mortar with siliceous fly ash and / or granite powder and that these materials do not deteriorate the surface of mortar samples. The most similar results of abrasion resistance to reference samples with only Portland cement were obtained for combination of fly ash and granite powder. The application of ANN to predict abrasion resistance of tested mortars showed very accurate results with the network's worst quality at 0.967 (with 1.0 as ideal result). The quality of the network relies on properly selected and detailed inputs. This study proved satisfactory results of predicting abrasion resistance based on mortar's components only.
