Influence of Glass Powder on the Properties Of Concrete

Abstract

Abstract-Glass is commonly used in building / construction industries and large amount of glass is powdered daily. The disposal of waste glass is an environmental issue as waste glass causes disposal problem. Today the construction industry is in need of finding cost effective materials for increasing the strength of concrete structures. Glass powder finer than 600 µ is reported to have pozzolanic behaviour. An attempt is made to investigate the possibility of using the waste glass powder as the partial replacement of ordinary Portland cement in concrete. Concrete with replacement of cement by waste glass powder such as 5%, 10%, 15% and 20% were produced and properties of this concrete has been compared with concrete of control mix with no replacement. Cube specimens of 24 numbers were cast, cured and tested for 7 day and 28 days strength. Compression test was conducted and the results were compared. The findings revealed an increase in compressive strength with the increase in the replacement of cement by glass powder. To reduce the demand for cement, glass powder replacements can be adopted. The replacement of glass powder decreases the unit weight as well as the porosity as indicated by the decrease in water absorption. It reduces the quantity of cement to be used in concrete. Also glass powder is proved to be economical and is considered as environmental friendly construction material.

Utilization of waste glass in the improvement of concrete performance: A mini review

“…The strength obtained at constant rates and at 84 days of testing of M2 (10%), M3 (15%) and M4 (20%) mixture achieved 88% compressive strength of the control concrete. Bhat and Rao (2014) concluded that the compressive strength of concrete containing 20% of glass powder presents a maximum strength compared to control concrete; this result is consistent with Sakale et al (2016). Figure 3 shows the different compressive strength results as a function of glass powder content in the concrete.…”

“…This is due to the low-density value of glass used (2.58) compared to cement (3.15). The same result was confirmed by Bhat and Rao (2014). Keerio et al (2017) observed that the density of hardened concrete increases with the substitution of 5%, 10% and 15% of cement by glass waste; the maximum increase of 1.25% in the control concrete was observed when replacing 10% of cement by glass powder.…”

A Step towards Concrete with Partial Substitution of Waste Glass (WG) in Concrete: A Review

“…That is why density is one of the most critical factors that must be considered during concrete mix designs. Concrete density with glass is shown in Figure 5 as per past studies [ 49 , 60 , 61 , 67 ]. A study reported that concrete density is 1.25% more than the reference concrete at 10% substitution of waste glass by the weight of binders [ 68 ].…”

A Review on Using ANOVA and RSM Modelling in The Glass Powder Replacement of The Concrete Ingredients

“…ANOVA is very useful when examining the multi-item scales mutual in market research. The author functioned in the research of [15] illustrated that the glass is an unknown substantial containing a high percentage of silica content (SiO2) i.e.72% with waste glass once ashore to a highly fine powder (600 microns) responds to alkali in cement & cementations production in assisting the donate to a strong expansion.
