This document discusses the comparison of materials for civil engineering structures. It explains that materials are compared based on their phase, such as solid, liquid, or gas, and their internal structure and chemical composition. Key factors for choosing the proper material include strength and durability requirements, economy considerations, and environmental and health/safety impacts. Strength requirements depend on the type of loading, such as permanent, repeated, or impact loads. Economy factors include initial cost, lifespan, and maintenance costs. Environmental impacts and health/safety issues must also be considered when selecting building materials.
