This research investigated the feasibility of using cellular glass insulation waste as fine aggregate in concrete paving block production. The effect of mixing proportions of cellular glass insulation waste at 0-40% by volume was studied. Results show that the amount of cellular glass waste can be used as a substitute for fine aggregate or sand up to 20%. Concrete specimens tested for compressive strength were found to be within an acceptable range of the interlocking concrete blockpavingstandard set byThailand Industrial Standards Institute. The compressive strength at 28 d was 41.50 MPa, with density ranging from 2.18 to 2.20 g cm-3. Thus, recycling of cellular glass wastes forconcrete paving block production can reduce expenditures in purchasing natural aggregates and can minimize environmental impact attributed to solid waste disposal.

Electrical and electronic waste (E-waste) has become a great matter of concern all around the world. Due to the fast growth in kinescope technology, Cathode Ray Tubes (CRTs) are being replaced by lighter and thinner panels with flat displays, namely – Light Emitting Diodes (LEDs), Plasma Display Panels (PDPs) and Liquid Crystal Displays (LCDs). The environmental hazards caused by CRTs waste generation have become an extensive dilemma around the globe. Lead is contained in sufficient amounts in the waste CRTs, which causes serious hazards to human health and the environment. The increasing demand for concrete and natural resources due to swift urbanization has made it crucial to replace the natural aggregates in concrete either as a partial replacement or total replacement, without affecting the concrete performance. CRT waste glasses are abundant in silica, have low water absorption property and adequate intrinsic strength. These characteristics of CRT waste glass make it apt for usage as pozzolan or sand in construction materials. They can be partially or totally replaced for natural sand as fine aggregate in concrete. This review work extends an in-depth summary of literature detailing the reuse of CRT glass waste as a fine aggregate replacement in concrete. The properties such as water performance, thermal property, strength and durability of CRT glass waste-based concrete and their method of manufacturing have also been studied in this paper. Furthermore, a comparative performance analysis of CRT glass waste concrete with other E-waste incorporated concrete has also been included in this paper. The current work shall contribute to enhancement towards sustainability and economic development of CRT glass waste incorporated concrete in the construction industry. Thus, the issues related to CRT glass waste such as contamination of soil, environment and water bodies, health issues caused to living beings and simultaneously, the degradation of natural restricted aggregate resources could be reduced considerably by several folds.

The shortage of natural aggregates has recently emerged as a serious problem owing to the tremendous growth of the concrete industry. Consequently, the social interest in identifying aggregate materials as alternatives to natural aggregates has increased. In South Korea’s growing steel industry, a large amount of steel slag is generated and discarded every year, thereby causing environmental pollution. In previous studies, steel slag, such as blast furnace slag (BFS), has been used as substitutes for concrete aggregates; however, few studies have been conducted on concrete containing both BFS and Ferronickel slag (FNS) as the fine aggregate. In this study, the compressive strength, chloride ion penetrability, and carbonation characteristic of concrete with both FNS and BFS were investigated. The mixed slag fine aggregate (MSFA) was used to replace 0, 25%, 50%, 75%, and 100% of the natural fine aggregate volume. From the test results, the highest compressive strength after 56 days was observed for the B/F100 sample. The 56 days chloride ion penetrability of the B/F75, and B/F100 samples with the MSFA contents of 75% and 100% were low level, approximately 34%, and 54% lower than that of the plain sample, respectively. In addition, the carbonation depth of the samples decreased with the increase in replacement ratio of MSFA.

Recycling is one way that is used to minimize the amount of waste that exists. Recycling is also a process to reduce the use of new raw materials, reduce energy use, reduce pollution, land degradation and greenhouse gas emissions. Materials that can be recycled consist of waste of glass, plastic, paper, metal, textiles and electronic goods. Glass has characteristics suitable as concrete aggregates, considering that glass is a material that does not absorb water. In addition, glass has high abrasion resistance. Meanwhile, the waste glass flux lowers the temperature to the temperature at which the formers will melt. Stabilizers in glass waste are made of calcium carbonate, which makes the glass waste solid and water-resistant. This glass waste is recycled by mixing it into the concrete mix. The recycling method is done by pounding the glass and putting it into the concrete mix stage. The purpose of mixing the glass waste is expected to increase the compressive strength of concrete. The use of glass waste as a mixed material affects the compressive strength of the concrete. The concrete with the most inferior to highest compressive strength is 4% variation concrete, 2% variation concrete, and traditional concrete. Optimal percentage addition of glass waste impacts on maximum concrete compressive strength is 2% mixture variation which obtained 11,88 Mpa & 11,32 Mpa.

Concrete is one of the construction materials of combination between cement, fine aggregate, coarse aggregate, and water mixed into one solid mass. The work of concrete making can be added a mineral additive as well as chemical additive (admixture) for the interest in construction work. In some cases construction work is desirable for concrete to produce optimum strength during the early age of the concrete so that the timing of concreting work can be shortened. The strength of concrete at the early age can be increased with added mineral (additive) and chemical (admixture) materials. This research made a mixture of concrete with 7 variations of mixture with total specimen 54 sample of cylindrical size with diameter 15 cm and height 30 cm. Tests conducted in the form of testing workability and compressive strength of concrete at the age of 3 days, 7 days and 28 days. Through this study obtained the right composition to make concrete with a high early age of compressive strength.

Polyethylene Terephthalate (PET) and Polypropylene (PP) is mostly used materials for making items like water bottles, food containers and many other plastic products in all fields of life. Due to the scarcity of natural aggregates for making concrete, it is required to go for alternative material, this type of plastic is one of the materials for replacement of fine aggregate in concrete. An objective of this paper is to study the feasibility of this recycled PET and PP plastic waste to be used as a building material in manufacturing of concrete which is replaced in fine aggregate. Polyethylene Terephthalate and Polypropylene is used in various percentages like 5%, 10%, 15% and also various tests like workability and compressive strength, Sorptivity, water absorption, acid attack and sulphate attack tests are conducted. From the results the PP shows good workability but low compressive strength than PET. From the durability point of view, the concrete made with PET and PP have given better results compared to conventional concrete of M30 grade. In PET and PP concrete, PET resists the acid, sulphate and water over the long period much better than the PP. So, PET can be replaced up to 10% in fine aggregate, whereas PP is allowed up to 5% replacement of fine aggregate.

Reactive Powder Concrete (RPC) can be incorporate as a one of the most important and progressive concrete technology. It is a special type of ultra-high strength concrete (UHSC) that’s exclude the coarse aggregate from its constitutive materials. In this research an experimental study had been carried out to investigate the effect of using three types of materials (porcelain aggregate) and others sustainable materials (glass waste and granular activated carbon) as a partial replacement of fine aggregate. Four percentages had considered (0, 10, 15 and 20) % to achieve better understanding for the influence of these materials upon the compressive strength of RPC. Four curing ages had included in this study, these are; 7, 28, 60 and 90 days. The outcomes of the experimental works improved that using porcelain aggregate as a partial replacement had an advanced effect on the compressive strength for all the adopted percentages and for all the studied curing ages. The maximum modification that’s obtained in case of porcelain aggregate was (24.14) % at age (90) days for 20% replacement. Using glass waste caused an increase in the overall values of the compressive strength for all the adopted replacements with less efficient than porcelain to reached (20.69) % at age (90) days for 20% replacement. Regarding the granular activated carbon, only (10%) replacement had a positive influence on the compressive strength to reached (13.16) % while the others caused a reduction in the compressive strength reached to (29.13)% for 20% replacement.

Experimental work was carried out to study new fine aggregate shielding construction materials, namely black sand (BS). The BS effect on the mechanical, durability, and shielding characteristics of heavyweight high-performance concrete (HWHPC) was evaluated. This study aimed at improving various HWHPC properties, concertedly. Fifteen mixtures of HWHPC were made, with various variables, including replacing 10% and 15% of the cement with fly ash (FA) and replacing normal sand by BS at various contents (15%, 30%, 45%, 60%, 75%, and 100%). The test specimens were subjected to various exposure conditions, including elevated temperatures, which ranged from 250 °C to 750 °C, for a duration of 3 h; magnesium sulfate (MS) exposure; and gamma-ray exposure. The effects of elevated temperature and sulfate resistance on concrete mass loss were examined. The results revealed that BS is a promising shielding construction material. The BS content is the most important factor influencing concrete compressive strength. Mixes containing 15% BS demonstrated significantly better strength compared to the control mixes. Exposure to 250 °C led to a notable increase in compressive strength. BS showed a significant effect on HWHPC fire resistance properties, especially at 750 °C and a significant linear attenuation coefficient. Using 10% FA with 15% BS was the most effective mixing proportion for improving all HWHPC properties concertedly, especially at greater ages.
