Aggregate being suitable for the use in concrete may reduce the impact glass has on the environment but the economic viability has to be taken into account in order to expand on the use of glass in concrete.The use of waste glass in concrete is a viable secondary market.
The use of these wastes as fine aggregate in concrete showed that when a 20 replacement of glass wastes were used an increment of 15 and 25 in the compressive strength at the ages of 7 and 28 days respectively.Also, the use of glass wastes in concrete may have an economic and environmental impact.
Using recycled glass in concrete.Conventional concrete aggregate consists of sand fine aggregate and various sizes and shapes of gravel or stones.However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials.
Articleosti7310891, title use of recycled concrete as aggregate.Final report, author buck, a d, abstractnote supplies of natural mineral aggregates are diminishing as their usage increases.Disposal problems exist because of steadily increasing accumulation of solid wastes.In light of these two situations an investigation was made to evaluate the use of crushed waste concrete.
2 the extensive research on recycled concrete aggregate and recycled aggregate concrete rac as started from year 1945 in various part of the world after second world war, but in a fragmented manner.First effort has been made by nixon in 1977 who complied all the work on recycled aggregate carried out between 1945-1977 and prepared a state-of.
Aggregate can be incorporated as coarse aggregate concrete without any long term detrimental effects and with acceptable strength development properties.Fine aggregate cant be replaced by plastic material so only coarse aggregates are used 2.The strength decreases drastically after replacing more than 20.
This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete.An experimental program based on two variables proportion of fine aggregates replacement and proportion of coarse aggregates replacement was implemented.The proportions of replacement were 0, 50, and 100 by mass of aggregates.
In the road construction process, different techniques have been proposed and used in order to reduce the financial implications involved while improving or maintaining the quality of the construction.This study was carried out to investigate the effect of using crushed glass as coarse aggregate on the compressive strength and workability of concrete used for rigid pavements.
Hongjian d k and kiang hwee tan, concrete with recycled glass as fine aggregates, aci materials journal title no.Mageswari and dr.S, the use of sheet glass powder as fine aggregate replacement in concrete, the open civil engineering journal, vol.
Glass can be used as a lightweight aggregate.However, the use of glass in concrete raises concerns about durability because of its poor stability in alkaline environments.This paper presents a study aimed at investigating the durability of lightweight concrete lwc made with expanded glass and silica fume used, respectively, for.
Use of glass wastes as fine aggregate in concrete.Maximum size of coarse aggregate was 125 mm a sieve analysis conforming to is 3831970 was carried out for both the fine and coarse aggregate concrete may be produced as a dense mass which is practically artificial rock and chemicals may be.
Use of glass wastes as fine aggregate in concrete.Aggregate in mortars and concrete.Estimated cost for housing is more and some construction materials like natural sand are also becoming rare.Waste glasses are used as aggregates for concrete.In this study, an extensive experimental work was carried out to find the suitability of use of.
The results showed that when all the fine aggregate is replaced by heavyweight waste glass in rc members, the heavyweight waste glass substitution ratio affected the crack occurrence patterns, and the possibility of a sudden failure of a member increased owing to concrete.
Fine aggregate in the mix proportion of concrete was replaced with plastic bag waste sand at 10, 20, 30 and 40 whereas other concrete materials remain same for all four mixes.In fresh properties of concrete it was observed from the results of slump test.
To check the effectiveness of fine aggregate replacement by recycled glass powder in concrete.Study the influence of waste glass on properties of hardened concrete mixes such as strength, modulus of elasticity and splitting resistance.To evaluate the recyclability of powdered waste glass as partial replacement of fine aggregate in the concrete.
Experimental plan in this work, 5, 10, 15 ,20 and30 of fine aggregate is replaced by glass powder for m20 grade concrete.Cube specimens of size 150 mm x 150 mm x 150 mm were casted for different proportions with glass powder and compared with the properties of concrete prepared without glass powder control mix.Compression test was.
