MABUHAY!
Another quality issue that requires a careful study on what rectification method to apply is the concrete hairline cracks. This is the most common punch list for rectification during the handover phase of a building construction. Concrete has relatively high compressive strength, but is significantly lower in tensile strength, and as such is usually reinforced with materials that are strong in tension (often steel). The elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. Due to shrinkage and tension, all concrete structures will crack to some extent. Concrete hairline cracks manifest in many ways:
