Fiber reinforced concrete (FRC) is an advanced form of the reinforced concrete cast by mixtures of cement, mortar, or concrete and discontinuous, discrete, uniformly distressed suitable fibers. Many researchers prove that the addition of small, closely spaced, and uniformly dispersed fibers to concrete plays the role of cracker arrester and substantially enhance its static and dynamic properties.
Curing of Heat Resisting Concrete or Refractory Concrete The main aim of concrete curing is to keep concrete moisture and continue hydration reaction for concrete to obtain sufficient strength. Inadequate curing will lead to not only dusty and friable concrete surface but also it causes the concrete to fail under service loads.

The refractoriness of refractory concrete is almost the same as that of refractory bricks of the same material, but because of refractory concrete (castable) without sintering, the initial heating shrinkage, so the load softening point is slightly lower than the bricks. However, on the whole, the performance is better than that of refractory bricks.
