Nov 26, 2008· 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.
Mostly, waste glass is used partially with cement, coarse aggregate and fine aggregate and sometimes as replacement of fine aggregate. Commercially, waste glass is already being used in architectural concrete or decorative concrete.
The results indicate that the concrete mixes containing waste glass show slightly reduction in compressive and tensile strength as compared with reference mixes. In this experimental study, the effect of using locally available waste windows glass as fine aggregate on the mechanical properties of concrete was investigated.
1. While using waste glass as fine aggregate replacement, 28 d strength is found to marginally increase up to 20% replacement level.IV 2. Marginal decrease in strength is observed at 30 to 40% replacement level of waste glass with fine aggregate. 3. Waste glass can effectively be used as fine aggregate replacement. 4.
Therefore, using waste glass as fine aggregate replacement in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources.
When waste glass is used as a fine aggregate substitute material, glass performance in hot mix asphalt should be comparable to conventional mixes. (14) Where larger, gravel-sized glass particles are used, raveling and stripping in particular could be a problem.
sand. The results indicate that the concrete mixes containing waste glass show slightly reduction in compressive and tensile strength as compared with reference mixes. In this experimental study, the effect of using locally available waste windows glass as fine aggregate on the mechanical properties of concrete was investigated.
Some of the specific glass waste materials that have found use as fine aggregate are "nonrecyclable" clear window glass and fluorescent bulbs with very small amounts of contaminants. Possible applications for such waste-glass concrete are bike paths, footpaths, gutters, and similar nonstructural work.
Jul 08, 2005· As for strength, glass aggregate can match, exceed or fall short of traditional aggregates, depending on size. Studies have found that very finely ground glass aggregate used in place of sand actually increases the strength of the concrete, whereas gravel-sized glass aggregate decreases strength. Mixing fine and coarse glass aggregates can have ...
Partial cement replacement with fly ash and mixing of glass with gravel aggregate were included in an attempt to find a suitable method of overcoming the expected adverse effects of the reaction between glass and cement alkalis. ... Title Waste Glass as Coarse Aggregate for Concrete
Dr. Haider.K.Ammash the possibilities Waste Glass of size up to 5mm as a fine aggregate in concrete. The waste glass was used as a partial weight replacement of sand with percentages of 10, 20, 30 and 40 %. They found that, waste glass aggregate can be satisfactorily substituted for natural fine aggregate at replacement levels up to 20%.
The present investigation was carried out to study the possibility of using waste glass of size up to 5mm as a fine aggregate in concrete and mortar.
fits may be derived from incorporating waste glass as a replacement for fine aggregate, with particle size limited to ensure detrimental ASR effects are mitigated. Recent studies which have focused on the suitabil-ity of using waste glass as a partial replacement for fine aggregate .
The results indicate that the concrete mixes containing waste glass show slightly reduction in compressive and tensile strength as compared with reference mixes. In this experimental study, the effect of using locally available waste windows glass as fine aggregate on the mechanical properties of concrete was investigated.
detrimental to the environment. Using waste glass in concrete has gained far more importance in parallel to environmental consciousness. In this project an attempt has been made to use the waste glass as partial replacement for both fine aggregate and coarse aggregate separately. For this M .

Laboratory experiments were conducted to further explore the use of waste glass as coarse and fine aggregates for both ASR (Alkali-Silica-Reaction) alleviation as well as the decorative purpose in ...
the thermal conductivity of concrete using crushed recycled glass as a fine aggregate. Influencing factors on thermal conductivity of concrete are investigated using The UnithermTM Model 6000 Guarded Hot Plate Thermal Conductivity Instrument. A total of 36 concrete mixes were
The Use of Waste Glass as a Partial Substitution for Fine Aggregate in Concrete Design Page 4 of 44 1 Background Information Engineering and construction activities consume, on average, 40% of the total global resource expenditure or 3 billion tons of raw materials (Roodman and Lenssen 1995).
industry is facing. In this paper, the issues of environmental and economic concern are addressed by the use of waste glass as partial replacement of fine aggregates in concrete. Fine aggregates were replaced by waste glass powder as 10%, 20%, 30% and 40% by weight for M-25 mix. The concrete specimens were tested for
ii. To study the compressive strength of concrete mode using glass waste as partial replacement of coarse aggregate. 2. MATERIAL & METHODOLOGY In order to study the effect of waste glass as partial replacement of coarse aggregate on the strength of concrete, fine aggregate, coarse aggregate 60 cubes and 6 cubes 0% waste glass for a mix have ...
The pozzolanic effect of waste glass in concrete is more obvious at the later age of 28 days. The optimum percentage of waste glass that gives the maximum values of compressive and flexural strengths is 20%. • Using waste glass as a partial replacement for fine aggregate did not produce any notable change in the concrete color. •
