The experimental test results revealed that maximum improvement was observed at 12% replacement of hill sand with waste glass on all investigated properties of concrete. Moreover, better improvement was observed with replacement of hill sand with waste glass fine aggregate WGFA1 than that of WGFA2.
Utilization of waste glass as sand replacement in cement mortar Nurhayat Degirmenci a, ... The ratio of cement, sand and water was 1:2.25:0.47, respectively. WG were used as replacement of LS sand with different colors and contents. In all mixtures, three different colors of WG were substituted in weight ratios of 10%, 30% and of each LS ...
Study of Concrete Involving Use of Waste Glass as Partial Replacement of Fine Aggregates M. Iqbal Malik, Muzafar Bashir, Sajad Ahmad, Tabish Tariq, Umar Chowdhary Students, B-Tech Civil Engineering, IUST, Awantipora, J&k, INDIA. Abstract: - Concrete industry is one of the largest consumers of natural resources due to which sustainability of
For checking strength effect of replacement of cement by glass powder, the cement is replaced at 10%, 20% and 30%. For study of size effect of glass powder the powder is divided in to two grades one is glass ... aggregates natural sand is provided with maximum size of 4.75 mm. Coarse aggregates are used with size between 20mm-4.75mm.
A number of different uses of such glass sand have been and are being tried. Local uses as a substitute for natural sand and gravel products may provide a local solution, but the income from the sale of glass sand is limited by the availability and prices of local aggregates. If
The gradation of glass sand was carefully selected to reduce effects of ASR. This led to non-uniform gradation between the two fine aggregates, with the glass sand displaying a lower fineness modulus (Ta-ble 2). These variations were accounted for during mix design process to ensure resulting concrete specimens were comparable.
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.
for accelerating the reactions between glass and cement hydrates, can accelerate the chemical reactions so that they occur at about the same time as hydration of cement. This enables partial replacement of cement with milled waste glass in concrete, and offers major energy, environmental and cost benefits.
replacement of cement in concrete for studying the strength property of concrete. The aim of the experiment is to find the maximum content of quarry dust partial replacement of cement in concrete. The percentages of quarry dust partial replacement of cement in concrete are 0, 10%, 15%, 20%, 25%, 30%, 35%, and 40%.
The potential use of waste recycled glass in concrete as recycled glass sand (RGS) and pozzolanic glass powder (PGP) was examined in this study. No major difference was found in compressive strength of concrete with the presence of RGS as sand replacement.
The referral conventional concrete as well as concrete made using silica sand as partial replacement of cement were tested for workability in green state and for compressive & split tensile ...
E) GROUND WASTE GLASS: This paper examines the possibility of using finely ground waste glass as partial natural sand replacement in concrete. It is produced in many forms such as packaging or container glass. was determined for different ground waste glass sand percentage replacement in concrete.
The use of ground waste glass as cement replacement has also been investigated due to its pozzolanic properties, with proportions up to 30%, . The results demonstrated a higher compressive strength of concrete made with ground glass than that made with fly ash.
PARTIAL REPLACEMENT OF FINE AGGREGATE BY GLASS POWDER IN CONCRETE 2. OBJECTIVE: To evaluate the utility of glass powder as a partial replacement of fine aggregate in concrete. To study and compare the performance conventional concrete and glass powder concrete. To understand the effectiveness of glass powder in strength enhancement.
shayam, 2004). Efforts have been made in the concrete industry to use waste glass powder as partial replacement of cement. Waste glass when ground to a very fine powder shows pozzolanicproperties as it contains SiO 2 and therefore to some extent can replace cement in concrete …
2. Early or 7 days strength increases rapidly with increase in the percentage of replacement by glass Powder up to a certain percentage. 3. When we replace sand with glass powder at 25% the strength of concrete is less than the strength of concrete at 20% replacement. Table 4: Results of the compressive test Type of cement % of sand replaced by ...
Glass is principally composed of silica. Use of milled (ground) waste glass in concrete as partial replacement of cement could be an important step toward development of sustainable (environmentally friendly, energy-efficient and economical) infrastructure systems.
cement paste and the interfacial transition zones in recycled aggregate concrete. Use of milled waste glass, as partial replacement of cement, is estimated to produce significant gains in strength and durability of recycled aggregate concrete. Milled waste glass was …
Utilization of waste glass as sand replacement in cement mortar ... [131,132], etc. are sand substitutes in concrete, while waste glass is used as sand replacement in cement ... replacement …
As the percentage of replacement of silica sand was increases 0% to 70% slump is increases from 4.84 % to 25.81% for mix – 1. By the replacement of silica sand in concrete, the compressive strength was decreases up to 30% replacement and then
(cement: sand) for 7, 28 and 96 days of curing as dipected in Tables 2, 3, 6 and 7. Likewise, a comparative study of compressive strength of the same mix by the same method of design is shown graphically in Fig. 1 and 2.
Use of glass wastes as fine aggregate in Concrete S.P. Gautam, Vikas Srivastava and V.C. Agarwal ... In order to study the effect of waste glass as partial cement replacement on the strength of concrete, fine aggregate and coarse aggregate, 66 cubes of size ... The properties of cement, coarse sand…
Glass aggregate can replace part or all of the sand and gravel in concrete, for effects that range from colorful terrazzo, to granite- or marble-like finishes, to concrete that reflects light like a mirror. Glass aggregate can even be used to produce concrete that literally glows.
paper, an attempt has been made to find out the strength of concrete containing waste glass powder as a partial replacement of cement for concrete. Cement replacement by glass powder in the range 5% to 40% increment of 5% has been studied. It was tested for compressive strength and flexural strength at the age of 7, 28 and 90 days and compared ...
Expanded polystyrene concrete; Crushed rubber: When vehicles tires reach the end of their usable life, they can still find some use as a replacement for course aggregate in concrete mixes."Crumb rubber" is crushed form of car or truck tires that are ground up between the sizes of 3 - 10 mm.
You can also use crushed glass as a substitute for sand. Just take care about the alkali-silica reaction using a mitigator addition, such as a metakaolin, etc. or even glass powder itself.
concrete as a replacement for sand. It is reported that the strength of fly ash concrete was more than 3 times higher than the sand concrete. More significantly, while the strength of sand mixes remained fairly constant be-yond 28 days, those of fly ash ed concrete at 56 and 180 days were up to 1.7 to 2.5 times higher than 28
