**Aggregates in Concrete Mixtures** **Objective:** Identify and discuss two examples of different types of aggregates, focusing on their shapes, textures, and sizes. Explore how these characteristics impact the concrete mixture. **Activity:** 1. **Select Two Aggregate Samples:** - Choose two distinct types of aggregates. Examples include: - Crushed Stone - Gravel - Sand 2. **Examine Aggregate Characteristics:** - **Shapes:** Describe whether the aggregates are rounded, angular, or flaky. - **Textures:** Note if the surface is smooth or rough. - **Sizes:** Measure and compare the size of different aggregates, ranging from fine to coarse. 3. **Discuss Impact on Concrete Mixture:** - **Workability:** How does the shape and texture affect the ease of mixing and pouring concrete? - **Strength:** Consider how size and texture contribute to the strength and durability of the finished product. - **Durability:** Examine how the aggregate type might influence the long-term performance of the concrete. Participate in discussions and experiments to gain a deeper understanding of how aggregate choices can optimize concrete in various construction applications.
