On the Behaviour of Recycled Aggregate Concrete Incorporating Slag
The concept of ‘sustainable development’ has now become a lead standard for the construction industry globally. In recent years, the utilization of recycled building materials became an important tool to achieve sustainability.
The work presented in this paper includes the results of an experimental research on the durability performance of various mixes of recycled aggregate concrete (RAC), incorporating 25% ground granulated blast-furnace slag (GGBS) as a cement replacement. The compressive strength, drying shrinkage, water penetration, water absorption, alkali aggregate reactivity, and sulphate content of the concrete mixes were tested. The results indicated that the addition of mineral slag improved the mechanical properties and durability characteristics of the recycled aggregate concretes. The addition of 25% GGBS proved to be efficient in reducing water absorption, alkali silica reactivity, and sulphate attack in RAC. However, the test results showed that the introduction of 25% GGBS is not effective enough in resisting water penetration and drying shrinkage of RAC mixes.
