Abstract Increasing amounts of glass waste present serious challenges in waste management to avoid environmental problems that might be created if it was to be deposited in landfills. Theoretically, glass waste is fully recyclable, but, if contaminated, containing impurities, broken or mixed colour, it makes the re-melting process impractical. A great practice of using secondary recycling material was reached by the construction industry involving glass waste in concrete mixtures as fine aggregates – reuse of waste glass in concrete production not only preserves natural resources, reduces greenhouse gas emissions, saves energy, furthermore, it may improve concrete sustainability and enhance the properties of concrete when used at the optimum quantity. In this study the container glass waste evaluation was performed, as well as experimental research of mechanical properties of four types of concrete mixtures containing glass waste as fine aggregate. The best alternative of replacement of sand by glass waste scenario in concrete production was determined, employing the multicriteria decision-making method TOPSIS.

Glass Dust

Glass dust waste creates chronic environmental problems, mainly due to the inconsistency of waste glass streams. Glass is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps in energy saving. The increasing awareness of glass recycling speeds up inspections on the use of waste glass with different forms in various fields. One of its significant contributions is to the construction field where the waste glass was reused for concrete production. The properties of concretes containing glass dust waste as fine aggregate were investigated in this study. Glass dust waste was used as a partial replacement for sand at 10%, 20% and 50% of concrete mixes. Compression strength for 7, 14 and 28 days concrete of age were compared with those of concrete made with natural fine aggregates. The results proved that highest strength activity given by glass dust waste after 28 days. The compressive strength of specimens with 10% glass dust waste content were 32.9373 MPa, higher than the concrete control specimen at 28 days. Using glass dust waste in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources.

Over Exploitation

Over-exploitation of natural river sand and waste oyster shells (WOS) dumped randomly will cause serious environmental issues. Thus, a drive to using crushed WOS as fine aggregates to substitute river sand in concrete production has been initiated. This paper conducted experimental research to study the possibility of employing the crushed WOS as 100% fine aggregates in concrete. The workability, compressive strength and its size-effect, and sustainability performance of the concrete mixtures were investigated. The results indicated that, under the same water-cement ratio, the WOS concrete showed a great improvement in strength properties while a decline was found in slump tests, compared to the control concrete. Besides, the use of the crushed WOS in concrete production resulted in a modification in both eco-efficiency and cost-efficiency.

Strength And Durability

In recent years, the construction industry has been faced with a decline in the availability of natural sand due to the growth of the industry. On the other hand, the metal casting industries are being forced to find ways to safely dispose of waste foundry sand (FS). With the aim of resolving both of these issues, an investigation was carried out on the reuse of waste FS as an alternative material to natural sand in concrete production, satisfied with relevant international standards. The physical and chemical properties of the FS were addressed. The influence of FS on the behaviour of concrete was evaluated through strength and durability properties. The test results revealed that compared to the concrete mixtures with a substitution rate of 30%, the control mixture had a strength value that was only 6.3% higher, and this enhancement is not particularly high. In a similar manner, the durability properties of the concrete mixtures containing FS up to 30% were relatively close to those of control mixture. From the test results, it is suggested that FS with a substitution rate of up to 30% can be effectively used in concrete production without affecting the strength and durability properties of the concrete.

The advantages of coconut coir powder (cocopeat) are resistant to microorganisms, weathering and resistant to mechanical spelling, namely friction and blows. Based on these advantages, cocopeat can be used as a blend of fine aggregates in the manufacture of concrete. The sieve test was conducted on the cocopeat to determine the initial feasibility analysis of cocopeat as a blend of fine aggregates in the concrete manufacturing. The results of the cocopeat sieve test are that cocopeat is included in Region II which is classified as a fine module of slightly coarse grains with a fine module of fine aggregate grains of 2.37. This shows that cocopeat has a fairly good value in normal concrete mixtures but is not suitable for high resistance concrete mixtures that exceed 25 MPa. This was followed by a subsidence test that gave subsidence values for mixtures of concrete with a cocopeat composition of 25%, 50% and 75%, is 7.5 cm; 5.3 cm; and 2.2 cm. While a good subsidence ratio is used in the range of 6-18 cm. In addition, the concrete with a 25% blend of cocopeat has a stronger physical form and there are no fungus growing on the surface of the concrete. Meanwhile, concrete with a mixture of 50% and 75% cocopeat looks more fragile and forms molds on the surface of the concrete. Thus the concrete with a mixture of 25% cocopeat has better results.

The challenge before the construction industry is to meet the demand of the efficient and economically viable construction materials posed by the huge infrastructural needs. Many nations are observing an expeditious growth in the field of construction necessitating the utilization of natural reserves for the expansion of infrastructure. This expansion is giving a warning to available reserves of nature. The natural ingredients, fine aggregates and coarse aggregate constitute more than 70% volume of the concrete. The availability of these resources is decreasing at a very high pace. In fact due to the severe problem with the availability of natural sand, the construction industry is faced with the pressing need to consider available options to lessen the reliance on natural aggregates. Copper slag being a waste material, can be used as an option for fine aggregates. The substitution of fine aggregate from nature with waste materials from industries such as copper slag offers economic and technical dominance, which are of pronounced significance in the present scenario. This study is, based on the critical review of the development of High Performance Concrete (HPC) by replacing fine aggregate with copper slag by observing various other researches and reviews. The key intent of this paper is to closely look at the copper slag utility as an unconventional material to be used as a substitute of fine aggregate and its effect on mechanical and durability parameters of HPC.

Highways are important transportation infrastructures that influence economy, culture, and security. Most of the highways in Indonesia are flexible pavement that use asphalt as a binder. The use of scrapped tire rubber as a partial replacement of fine aggregates is based on the limited available natural aggregate in nature. Utilization of scrapped tire rubber as a fine aggregate is one of the alternatives for reducing environmental pollution and supporting Clean Development Mechanism program. The aim of this study is to analyze the Marshall test characteristics of asphalt concrete (AC) mixture that use scrapped tire rubber as a partial substitute of fine aggregate and comparing with a standard mixture. Laboratory tests are performed on three different types of mixtures as follows the mix without scrapped tire rubber, mix containing 50%, and 100% substitution of aggregate at fraction of No.50 with scrapped tire rubber. The test, it show that optimum asphalt content for ACStandard mixture is 6.76%, while ACScrapped-tire 50% mixture is 7.04% and ACScrapped-tire 100% mixture is 6.25%. The use of scrapped tire rubber in asphalt concrete mixtures can improve the resistance to permanent deformation and resistance to water. The use of scrapped tire rubber is acceptable as a partial replacement of aggregate in asphalt concrete mixtures.

Concrete is the major composite material used in construction industry, it is strong in Compression and weak in tension and also has high self-weight. The light weight concrete was a alternative to conventional concrete due its low weight it decreases the self weight. Comparatively by using the light weight materials that occur either naturally or industrial waste, these material helps in reducing the cost and to improve the performance. Presently in India, more than 960 million tones of solid waste were being generated annually as by-products during industrial, agricultural mining and other processes. This paper deals with coconut shell concrete, which is one of the solid waste in the environment, and the use of this coconut shell as a replacement to coarse aggregate will reduce the weight of concrete by 25%. The other waste that was disposed mostly was sawdust. It was a byproduct of cutting or drilling of wood with saw or other tool. It is composed of fine particles of wood. It is having many advantages over traditional concrete like low bulk density, better heat preservation and heat insulation property. As said earlier to make concrete strong in tension coconut fiber is added, which is a waste material that left to disposal and as it is strong and stiff will hold the concrete material and also controls the crack. This study investigates on the use of sawdust as partial replacement for fine aggregates in concrete production. Sawdust was used to replace fine aggregates in Conventional and as well as in Coconut Shell concrete from 0%, 5%, 10% and 20%. M25 grade of concrete was selected and testing is evaluated at age of 3, 7 and 28 days. From the results, increase in percentage of saw-dust in concrete cubes led to corresponding reduction in compressive strength values, and the optimum saw-dust content was obtained at 5% in conventional as well as in coconut shell concrete , coconut fiber was added at the optimum value of sawdust on conventional and coconut shell concrete at 1%,2%,3%,4% and 5%. The better strength was obtained at 2% addition of fiber in coconut shell concrete and at 3% addition in conventional concrete.
