The use of glass powder in concrete production can make the construction industry more environmentally friendly. Glass can be re-used as a fine raw material and it presents a possibility to save natural, non-renewable materials. Within the scope of this experimental result, it was confirmed that the estimation equation proposed in this study accurately represented the creep behaviour of concrete at early age.Įvery year there are several hundred tons of waste glass produced in Latvia. In addition, based on the experimental results, an estimation equation for creep strain at early age was proposed. As the result of the experiments, it was shown that the creep strain is proportional to the load stress of concrete at an early age and the strain of specific creep decreases as the loaded age increases. Therefore, in this study, experiments were carried out for concrete at early age within one week. Therefore, it is necessary to evaluate the creep behaviour of concrete at early age and to establish a convenient test method to estimate the creep behaviour. Currently, it is difficult to accurately perceive the creep behaviour of concrete at an early age in the test method of creep which is generally carried out. However, most past researches on creep behaviour were investigated after 28 days. Clarifying the creep behaviour of concrete at early age not only improves the accuracy of temperature stress analysis but also contributes to prediction accuracy and control measures in cracks caused by thermal stress.
