Properties of Concrete at Elevated Temperatures

5, 6].Concrete generally provides the best fire resistance properties of any building material [].This excellent fire resistance is due to concrete’s constituent materials (i.e., cement and aggregates) which, when chemically combined, form a material that is essentially inert and has low thermal conductivity, high heat capacity, and slower strength degradation with temperature.

Normal Concrete vs High-Strength Concrete Properties and

High strength concrete has a lower value of permeability compared to normal strength concrete. which is because the high-strength concrete is designed with a lower water-cement ratio. The silica fume is commonly used in the mix. The high strength concrete has permeability ranges from 1 x 10 -11 to 1 x 10 -13 cm/sec.

High strength concrete properties, admixture, and mix

The time taken to achieve a specific strength is an important economic and design parameter in high strength concrete construction. In fact, a high early strength may bring far more practical and economic benefits than a high strength at a later age, in terms of early removal of formwork, increased productivity of precast units, early transfer of pre-stress, and early application of service loads.
