Stress, σ, is defined as the force divided by the initial surface area, σ=F/A o . This pulling stress is called tensile stress. Strain is what results from this stress. Strain, ε, is defined as the change in length divided by the original length, ε = Δ I / I o. Before we proceed further …

Concrete is relatively weak under tensile stresses. When a structural component is bent, it undergoes both lengthening and shortening at the same time. The following figure shows a concrete beam subjected to a bending force. Its upper part is elongated due to the tensile stress whereas the bottom part is shortened due to the compressive stress.

2. Reactions of binders in cement-based composites2.1. Hydration mechanism of cement. Cement clinker contains about 75% chemical compositions (% by total weight) of alite or tricalcium silicate (C 3 S) and belite or dicalcium silicate (C 2 S). When C 3 S and C 2 S of cement react with water, they produce crystalline calcium hydroxide (Ca(OH) 2) and calcium-silicate-hydrate …

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Compressive stress is the stress on materials that leads to a smaller volume. When the compressive stress is applied to the materials that are brittle, these materials fracture as there is a sudden release of the stored energy. Whereas when the compressive stress is applied to the materials that are ductile, they compress and there is no failure.
