“…At present, the common way of stone powder addition in pavement construction is replacing fine aggregate or cement with stone powder as a mineral admixture. At present, stone powder has been widely used to replace the traditional pure river sand in the pavement concrete construction in China 10,11 …”

At present, due to the unclear understanding of the mixed proportion of stone powder in the manufactured sand, the quality of finished concrete is affected. In this study, the concrete was mixed with manufactured sand containing 0%, 5%, 10%, and 15% stone powder and poured into standard models. The compressive strength of the concrete was obtained by measuring the pressure; the dry shrinkage rate of the concrete was obtained by measuring the volume; the impermeability was evaluated by the seepage height method. The results demonstrated that the increase of stone powder content resulted in the enhancement of concrete compressive strength and impermeability, but blindly adding stone powder led to the deterioration of concrete anti‐shrinkage performance. Finally, the comparison of the overall experimental data showed that 10% of stone powder could make all aspects of the performance of the concrete optimal.

“…The outcomes defined that the 25% replacement exhibited maximum strength among other percentages. RIS was used in [16] as fine aggregate replacement in concrete of various grades. Fine aggregates were fully replaced in M15, M20 and M25 grade concretes and their tensile strength was compared with concrete containing no replacement.…”

As the demand for concrete rises, the concrete materials demand increases. Aggregates occupy 75% of concrete. A vast amount of aggregates is utilized in concrete while aggregate natural resources are reducing. To overcome this problem, River Indus sand (RIS) and recycled concrete aggregate (RCA) were utilized as fine and coarse aggregate respectively. The aim of this experimental investigation is to evaluate the workability, and compressive and tensile strength of concrete utilizing RIS and RCA. Concrete samples of 1:2:4 proportions were cast, water cured for 7, 14, 21 and 28 days, and tested for compressive and tensile strength. The outcomes demonstrate that concrete possessed less workability when RIS and RCA were utilized. It was predicted that compressive strength of concrete would reduce up to 1.5% when 50% RIS and 50% RCA were utilized in concrete and 11.5% when natural aggregate was fully replaced by RIS and RCA, whereas the tensile strength decreased up to 1.60% when 50% by 12% respectively.

“…It is viable, robust and cost-effective as compared to other conventional building materials [1]. Flexural and tensile strength of concrete is low; however, it is very strong in compressive strength as concrete is brittle in nature [2]. Thus, in order to improve the flexural strength and tensile strength, various types of fibers are mostly used as reinforcement [3].…”

The main objective of this research work is to investigate the influence of the addition of waste materials, like aluminium waste material, Soft Drink Tin Fibers (SDTF) or soft tins to improve mechanical properties of concrete and also study the strength behavior of concrete, such as flexural strength and indirect or split tensile strength. It has been acknowledged that the use of fibers in concrete has considerable effects to improve strength parameters and characteristics of concrete. In this research work, similar efforts are made to present the effects of soft tin fibers or aluminium waste material as a reinforcing material in concrete and to assess the mechanical behavior of concrete. Particularly, this research work aimed to investigate experimentally the effect of soft drink tins on tensile (cylinder splitting tensile strength) and flexural strength. Soft tin fibers of 25.4 5 0.5 mm in size were used and added from 1 to 5% by the weight of cement with the design mix of 1:1.624:2.760 at 0.50 w/c ratio. Therefore, 6 batches (every batch contained 3 prisms and 3 cylinders) were prepared and cast for evaluation of tensile and flexural strength. One batch was cast without inclusion of fibers (controlled batch) and remaining 5 batches were cast with the addition of fibers using 1, 2, 3, 4, and 5% respectively. It was revealed from obtained results that split tensile strength and flexural strength of specimen increases as compared to controlled batch up to 4% addition of fibers. Moreover, beyond 4% soft drink tin fiber level, strength begins to fall down. Thus, it can be suggested that mechanical properties of concrete can be enhanced by 4% of soft drink tin fibers. Moreover, in this study, soft drink tin fibers (SDTF) or aluminium waste are used as the application of utilization of waste materials as a partial construction material and also on another side it controls the solid waste and environmental pollution.
