Experimental Study on Mechanical Properties of Concrete Containing Waste Glass and Its Application on Concrete-Filled Steel Tubular Columns

Waste glass (WG), as a nonbiodegradable material, poses a threat to environmental protection. The reuse of WG as a raw material to replace cement or aggregate in concrete production is gaining attention for recycling purposes. However, the optimal proportion of WG in concrete mixtures and its particle size distribution are hard to determine....

Drying shrinkage of alkali-activated slag concrete with natural/recycled aggregates

Each year a large amount of construction and demolition waste (CDW) is generated in the European Union. For sustainability development the CDW is recycled and re-used. To promote the use of CDW, recycled aggregates from CDW were incorporated in alkali-activated concrete (AAC), which mainly consisted of secondary materials or industrial by...

Properties of concrete blocks made with recycled concrete aggregates: From block wastes to new blocks

Large amounts of construction and demolition wastes (C&DW) especially concrete wastes are generated annually and will increase in the future. Until now, only a small fraction of concrete wastes is re-used as recycled concrete aggregates (RCA) in the manufacture of concrete. In this paper, the feasibility of using RCA obtained from old concrete...

Influence of the saturation state of recycled sand on mortars compressive strength

This paper investigates the water content of pre-saturated recycled concrete aggregates (RCA) that has a diameter of 1-4 mm called recycled sand (RS), in order to determine the degree of saturation of the RS. It also puts forward the effects of the saturation state of the RS on the mechanical properties. For this matter, experiments were...
