“…For comparison, in other studies [71], the reduction in compressive strength of recycled concrete (based on concrete waste aggregates) cubes after 30 days of immersion in 3% H 2 SO 4 was about 43.86%. Gireesh [72], in turn, proved that loss in compressive strength of recycled concrete (based on aluminum dross aggregates) mixes due to acid attack (5% H 2 SO 4 ) was in the range of 1.78–5.11%.…”

This paper presents the results of research aimed at finding the possible ways of disposing of ceramic waste material, focusing mainly on the possibility of using it as aggregates in concretes exposed to an aggressive chemical environment (municipal sewage). The research part presents the preparation method and investigation of waste ceramic aggregates (red, glazed and sanitary ceramic aggregates). A suitable ratio of coarse to fine aggregates was selected, and their density, absorptivity and crushing strength were examined. All examined aggregates were also subjected to SEM analysis. Red ceramic aggregate is characterized by a greater degree of crushing compared to glazed and sanitary ceramic aggregate, by 205.7% and 439.4%, respectively. Another part of the research was to compare the properties of concrete with traditional aggregate (gravel, basalt) and with ceramic waste aggregate. The tested parameters included consistency, apparent density, absorptivity, flexural and compressive strengths of concretes. The study proved that the absorptivity of recycled composites is higher than that of traditional composites by 20.8–24.7%. The concrete based on sanitary ceramic waste has the highest strength parameters. Its compressive strength is higher by 10.5% and flexural strength by 5.9% compared with the basalt aggregate concrete. The compressive strength of sanitary ceramics concrete is higher by 42% and by 59% compared with concrete based on glazed ceramic and red ceramic aggregate, respectively. The last part of the research was to examine the resistance of concrete to aggressive environment. The scope of the work included the preparation of the research environment in the form of solutions with an increased concentration of aggressive agents (hydronium, sulfate, magnesium, ammonium ions). Among the concretes with ceramic aggregate, the highest decrease in the compressive strength was demonstrated by the concrete based on red ceramics (128.2%), while the smallest was demonstrated by the concrete based on sanitary ceramics (aggregate from sanitary ceramics (15.4%). The mass loss at different time intervals and compressive strength loss of samples stored in solutions were tested. The smallest weight loss caused by aggressive environment attack was recorded in the concrete based on ceramic sanitary and glazed aggregate (20.2% and 34.5%, respectively, after 120 days of aggressive environment).

“…Aluminium dross ( Plate 1 ) is in abundance, and proper utilization of this waste product will be economical [5] , [6] , [7] , [8] , [9] , [10] , [11] . The research of [5] , [6] , [7] revealed common filler materials other than aluminium dross that has been used in the past and are still being used up till date in concrete and asphalt. Based on the findings of [2] , it was discovered that aluminium industries create almost five million tons of this waste every year.…”

Pavement is the backbone of an effective and efficient transportation system. Data on the use of aluminium dross as filler material in the modification of asphalt for a sustainable pavement was espoused. Aluminium dross which is a solid waste from steel production industry was utilized. Data on the engineering and stability properties of the material in enhancing the strength of the asphalt mix design was espoused. This was achieved by adding the solid waste at 0%, 2.5%, 5%, 7.5%, 10% and 12.5% of aluminium dross to the asphalt concrete sample. Marshall Test was used to determine the stability of aluminium dross in flexible pavement and this was used for the selection of asphalt binder content with a suitable density which satisfies minimum stability and range of flow values using AASHTO specification. The data obtained will be of help to researchers, engineers, road construction workers and environmentalist on the use of this solid waste in the construction of sustainable long-lasting roads for national growth and solid waste reduction.

“…According to PT. Wijaya Karya Beton, it would have been very difficult to obtain the natural sand with its sludge content of less than 5% [7] at some sand-producing quarries such as in Majalengka, Kuningan and Sumedang [8]. The use of local natural sand accompanied with high sludge content to fabricate a good good quality of concrete structure has been identified as a grand challenge facing civil engineering industry today and must be addressed in the further scientific research and data analysis [9][10][11].…”

The use of precast concrete structural systems in civil engineering industry in Indonesia will still increase due to the needs of buildings and infrastructure for social and economic development continuously increase from the year to year. In spite of the use of sand accompanied with its suitable sludge content has been widely used as one of the important raw materials for fabricating a precast concrete, the availability of low cost method to obtain a good quality of sand with its sludge content of less than 5% is difficult to find in many regions in the country. The aim of this study was to assess the performance of four cylindrical concrete specimen (CCS) samples by conducting the experiments of testing the natural sand with its high sludge content of 12.7% with using the different ordinary Portland cement (OPC) compositions of 2.5, 5.0, 7.5 and 10.0% and the super-plasticizer of polycarboxylate ether. Two CCS samples of the same composition (1) using the washed sand with its sludge content of 3.7% and (2) without addition of OPC were used as control. The results of compressive strength and slump test verified that the addition of OPC at least by 2.5% into concrete slurry to ensure optimal performance of the CCS samples can be recommended using the natural sand accompanied with its sludge content of 12.7%. This study concluded that the use of local natural sand with its high sludge content as long as the other material compositions used properly could be safe in the fabrication of precast concrete structure for the future civil engineering applications.
