| eu laws have been the most effective driving force of Latvian and Hungarian environmental legislation in order to improve recycling of packaging waste. in Latvia and Hungary the waste diversion strategies have focused on establishing treatment capacity and setting up schemes for separate collection, which largely cover packaging waste. Despite all improvements done in this area, still large amount of glass wastes is dumped into landfills and alternative solution for this waste glass utilization could be the application in concrete as a supplementary cementitious material (scm). Laboratory tests were carried out on cement paste specimens, in which waste glass powder (WGP) addition was used as a scm. cement was substituted with WPG at levels of 20% or 30% per mass. it was demonstrated that the WGP addition is applicable in view of drying shrinkage with total deformation up to 2.5 in the period of 592 days. the WGP addition contributes to a slowdown in the rate of hydration of the cement paste, so the early age shrinkage cracking tendency becomes more favourable, which can be seen in the longer cracking time result during the ring tests. |
