    Mar 10, 2020 The results highlight the recyclability of geopolymer concrete aggregates in the widely used Portland cement concrete as a viable end-of-life waste management option for geopolymer concrete. The decrease in compressive strength, modulus of elasticity, and flexural strength of RGAC at 20 RGA replacement were found to be only about 14, 1, and 3, respectively.

  • Potential For Using Waste Glass In Portland Cement

    Local recycling pressures are providing an impetus to examine the use of unconventional materials in construction such as waste glass in Portland cement concrete. It is well known that the silica in glass can be highly reactive with the alkalis in cement paste and that this reaction can lead to expansion and cracking of the concrete alkali-silica reaction or ASR.
