Answer: 3/8 inch crushed stone
Explanation: For a 4-inch thick concrete slab, the recommended size of aggregate varies depending on several factors including the intended use, local specifications, and the desired finish of the concrete. Here are some general guidelines:
1. Aggregate Size Range: The aggregate used in concrete for a 4-inch slab typically falls within the range of 3/8 inch to 1 inch in diameter. This size range ensures good workability while still providing adequate strength and durability.
2. Purpose of Aggregate Sizes: 3/8 inch to 1/2 inch: This size range is often used for fine to medium aggregate mixes. It helps improve workability and surface finish of the concrete. 3/4 inch to 1 inch: Coarser aggregates in this range are sometimes used for heavier-duty applications where additional strength and durability are required, such as in driveways or industrial floors.
3. Mix Design: The specific mix design of the concrete (proportions of cement, water, aggregate, and possibly admixtures) will determine the exact size and type of aggregate used. The mix should be designed to achieve the required strength and durability for the intended application.
4. Local Specifications: Always refer to local building codes and specifications for guidance on aggregate size and mix design requirements. These regulations ensure that the concrete meets structural and durability standards in your area.
5. Quality of Aggregate: Use high-quality aggregate that is clean, free of debris, and meets local standards for grading and size distribution.
In summary, for a 4-inch thick concrete slab, aggregate sizes ranging from 3/8 inch to 1 inch in diameter are commonly used, with the specific size chosen based on the intended use and local requirements. Adjustments to the mix design may be necessary based on factors such as load-bearing requirements and environmental conditions. | | Midtex Services | Answer: 5/8 inch crushed stone
