“…The results of water absorption (Figures 11 and 12) showed an increase in water absorption capacity with the increased sludge content in comparison to control samples for all curing ages, especially for mortars with high sludge content (>10%), which may affect the mortar durability. The roughness and irregularity can explain this increase, low fineness of sludge particles, and high-water absorption capacity of sludge particles [20,22], which contributes to the increase in the number of open pores of dried specimens, where water easily penetrates into mortar [15,24]. Also, according to Andrade et al [25] and Ramirez et al [26], the increase in sludge particles porosity due to the calcination process leads to the increase in water absorption of sludge samples.…”

This paper examines the possibility of using water purification wastes in the production of mortar. Within the study context, XRD and XRF analyses were performed to obtain the chemical composition of sludge. Moreover, heat-treated sludge at a temperature of 900ºC was used in the preparation of mortar mixes as a partial sand replacement (5, 10, 15, and 20% by sand weight) with a w/c of 0.48. Fresh mortars were tested for workability, and mortar samples with 7, 28, and 90 days curing ages were tested for dry density, absorption, ultrasonic pulse velocity (UPV), and compressive and flexural strengths. Besides, some regression modeling was conducted for each of the measured parameters. In general, the results showed that the use of up to 10% incinerated sludge by sand weight leads to a slight decrease in the workability and density of the mixture and a 10% increase in its strength. Nevertheless, mortars with sludge content of over 10% showed a significant increase in water absorption and a decrease in strength and other properties.

“…It was found that the ceramic waste should be deglazed, and a lower cement ratio be adopted to achieve the desired strength [24]. The study for manufacturing of roof tiles using industrial waste along with natural bers demonstrated that by mixing brous composites better mechanical properties and reduction in weight can be achieved [25,26]. The academicians had worked on the bers from the PET bottle wastes to improve the exural capacity of the concrete [27].…”

Strict environmental concern, depleting natural recourses and increasing demand of building construction materials has driven the scientific study towards alternative building materials. This research supports the idea of sustainability and circular economy via utilization of waste to produce value-added products. This research explores the potential of waste plastics and silica sand for the development of thermoplastic composite materials as floor tiles. The developed floor tiles were characterized for water absorption compressive strength, flexural strength and sliding wear. The morphological analysis of the sand-plastic interfaces was coved under the umbrella of this study. The maximum compressive and flexural strength obtained to be 46.20 N/mm2 and 6.24 N/mm2 respectively. Moreover, the minimum water absorption (%) and wear rate were found to be 0.039 and 0.143×10− 8 kg/meter respectively. The study suggests the workability of the developed floor tiles in non-traffic areas of public places. Thus, the study provides a green building material through recycling of waste plastics for sustainable development.

“…11 Mining processes generates considerable waste in which the net Kota stone obtained is 30%. 12 During the processing in gang saws, the chunks of stone create slurry with the Kota stone solid to produce Kota stone slurry. 13 Kota stone is a fine-grained waste having non-slipping surface and amorphous texture so it is also known as flaggy limestone.…”

Concrete is highly used construction material with cement being its major ingredient. Also, the demand for good quality of concrete is increasing because of the fast-growing urbanization. But there are certain problems associated with the manufacturing of cement. One of the major problems being production of carbon dioxide causing pollution in environment, the manufacturing of cement is quite expensive and it also leads to the depletion of resources. In order to curtail the consumption of cement, it has become inevitable to replace cement by certain amount with substituent materials that are cheaper to produce in order to lower down the financial cost of concrete production by some extent. The review paper, elaborates many properties of concrete by the inclusion of Kota stone slurry after evaluating several research papers. The following paper discusses numerous properties of concrete including workability, compressive strength, split tensile strength, water absorption and modulus of elasticity. The paper demonstrates that when used appropriately, inclusion of Kota stone slurry in concrete had a positive impact on concrete by increasing the strength and durability.
