“…A certain mass of cement was directly replaced by glass powder or fly ash in these mixtures without any adjustment in the contents of other ingredients in the mixture. However, a previous study has reported results where the w/cm of glass powder and fly ash modified mixtures was adjusted to produce similar workability as the control concrete [18]. Needless to say, such an approach will present the replacement materials in a better light, but the aim of this study is to show that the use of glass powder as a direct cement replacement without any other changes in the concrete mixture is feasible.…”

“…The sodium oxide content of the glass powder is very high, as is expected of soda glass. Detailed studies by the authors on hydration characteristics of cement and durability of concretes containing glass powder has shown that the high Na 2 O content in glass powder does not adversely influence concrete performance [18,19].…”

“…The amount of water taken in by the specimens was divided by the area exposed to water to obtain the normalized water intake. This test method, when continued for a long period of time, say 28 days, has been used along with a combined sorption-diffusion equation to extract the moisture transport parameters including long term sorptivity and moisture diffusion coefficient of a variety of plain and modified concrete mixtures [18,22,23].…”

This paper deals with studies on the use of waste glass powder as an effective ingredient in concrete. Studies on cement pastes including mechanical property tests and thermal analysis were used to understand the influence of the glass powder on the cement hydration process and to arrive at an optimal dosage range. Cast-in-place concrete and block mixtures were proportioned with varying dosages of glass powder, and tests for mechanical properties, alkali-silica reaction, and water absorption were carried out. The use of fly ash as a cement replacement material was also adopted in one of the concrete mixtures to compare the performance of glass powder and fly ash in concrete. Though the complete effect of cement dilution was not overcome by the chosen dosage of glass powder, the strength results were comparable to that of control concrete. Moisture intake results of glass powder modified concrete mixtures showed lower total water absorption as well as sorptivity than the control concrete when cured for a longer duration. The expansion due to alkali-silica reaction was also lower for the glass powder modified mixtures. For the concrete block mixtures, it was found that moist curing the blocks after initial steam curing was beneficial in strength improvement. Replacement of 10% cement with glass powder was found to result in equal or higher compressive strengths of the blocks. In regions where glass powder is locally available, its use as a cement replacement material presents an efficient waste management option, without compromising concrete performance.

“…Such operation allows increasing the alkali content to 2 %. When analyzing the chemical compositions of Portland cement investigated by different authors [2][3][4][5][6][7][8][9] we observe the quantity of R 2 O varied from 0.6 to 1.0 %. The majority of authors suggest substituting Portland cement for fine-grinded glass powder in the amount of 20-50 % and ignoring the effect of alkaline factor.…”

Abstract. 1 The effect of alkaline component in glass powder on the total alkaline content of cement-glass mixtures, which is limited by standards, has been investigated by means of pH-metry, titration and different extragents. Using experimental and calculated results concerning alkaline activity of glass powder it is possible to develop chemical structure of the cement composites which would meet the standards in regard to total alkaline content.
