The development of biodegradable polymers has seen considerable growth in recent decades, in particular biopolymer films based on cassava, potato and corn starch for packaging applications. Unfortunately, these biopolymers have weak thermomechanical

The reactivity of the recycled glass powder (GP) in a cementitious medium has been studied over time by means of X-ray diffraction and thermal gravimetric analysis. Two different mixtures based on cement/glass powder (0 or 20 wt% GP) and lime/glass p

Decreasing the pH value of a concentrated sodium silicate solution while maintaining its basic environment, largely affects solution stability. The charge modification induces by the presence of acidic species is expected to destabilize initial equil

As defined by the American Concrete Institute (ACI), alternative supplementary cementitious materials (ASCMs) and local materials are very important in concrete sustainability. As an ASCM, glass powder (GP) shows excellent pozzolanic properties. This

Glass powder (GP) obtained by grinding waste bottle glass has been recently introduced in construction materials as a supplementary cementing material (SCM). The behavior of SCMs strongly depends on surface chemistry, which governs their reactivity.

Metakaolin-based geopolymer materials reinforced with sand in tubular shape were developed, and their durability in acidic, neutral and humid environment was investigated. Results show that mechanical properties of materials are not affected by durab
