Fire resistance is one of the key factor which aids toward durability a structure. Concrete most widely used construction material and also an effective for structural fire protection. Physical thermal properties are to measure concrete. Three main reasons concrete are: non-combustible, non-toxic, low conductivity (concrete retain slow rate heat transfer). The lower value behaves like perfect s...

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...

Using of CFRP carbon sheets because of their high strength, lightness and ease of use have been very expanded in retrofitting concrete members. Including shear walls systems FRP can be used in order to rebuild or maintain the strength of an aged structural member. Repairing, or retrofitting of the intact structural member is conducted to enhance the structural resistance that was deteriorated d...
