TL;DR: In this article, a fine glass powder (GLP) was used for incorporation into concrete as a pozzolanic material to suppress the alkali reactivity of coarser glass particles as well as that of natural reactive aggregates.

TL;DR: In this paper, a field trial was conducted using a 40 MPa concrete mixture, incorporating various proportions of glass powder (0, 20, and 30%) as cement replacement, and the results demonstrated that GLP can be incorporated into 40MPa concrete at dosage rates of 20-30% to replace cement without harmful effects.

TL;DR: In this article, the surface properties of RCA and the influence of the improved RCA on the strength development and durability properties of 50 MPa-strength concrete were examined, including drying shrinkage, alkali-aggregate reaction, sulfate resistance, and chloride permeability.

TL;DR: In this article, the authors compare the expansion results obtained by the two test methods using a number of aggregates with known field performance and assess the validity of their expansion limits in predicting the field performance of these aggregates.

TL;DR: A hydroelectric concrete gravity dam in the Snowy Hydroelectric network had shown signs of concrete distress in the form of cracking in some sections of the dam wall, and vertical movements in the wall, measured in routine surveys on the crest of dam wall as mentioned in this paper.
