INNOVATIVE METHODS TO MITIGATE ALKALI-SILICA REACTION IN

Application of recycled glass as a cement or fine aggregate replacement in concrete could result in major benefits towards a more sustainable design of concrete materials. This is however only possible if the main obstacle, the alkali silica reaction (ASR), is properly addressed and the ASR damage is mitigated.

Experimental Study on Thermal Conductivity of Self

The shrinkage and creep of recycled concrete are maintained when coarse aggregate replacement is less than 20%, whereas with a 100% replacement of coarse aggregate, shrinkage can increase up to 50% and creep between 30% and 60%. If fine recycled aggregate is also used, both values increase even more.

Moisture Susceptibility of Sustainable Warm Mix Asphalt

The concrete is the most significant component in the construction and demolition waste. The management of these huge waste quantities is considered as a serious challenge due to the landfill shortage and transport costs. This leads to the introduction of the RCA concrete aggregate as an alternative sustainable material for asphalt mixes.
