Increased demand and decreased supply of aggregates for concrete production necessitate the search new aggregate sources. Environmental features are increasingly being used to evaluate construction materials. Concrete recycling is becoming more popular since it conserves natural resources reduces need disposal by using readily available as a source fresh concrete. Several studies on influence r...

This contribution deals with the possibility to use waste vitrified tiles (VT) in high-performance concrete. Silica powder normally used concrete is replaced by 25, 50, 75 and 100 %. The basic experiments are tested, such as water absorption, flexural strength compressive strength. durability examined, freeze-thaw resistance tested freeze cycles. results evaluated compared reference concrete, c...

Corrosion inhibiting admixtures are unique among other methods to protect reinforced concrete from corrosion damage. In this study, the effect of furfural on fresh and hardened properties mixes 35 45 MPa compressive strengths as well inhibition was evaluated. Furfural added at different dosages (1, 2 3% by weight cement) with without superplasticizer (HRWR). Different electrochemical measuremen...

Effort towards preserving natural coarse aggregate for future generation and reducing cockle shell waste originating from the fisheries industry has initiated studies on possibility of integrating this waste in concrete production. This paper presents the result on the workability and compressive strength of concrete containing various percentage of cockle shell content as partial coarse aggreg...
