For a 1 cu.m Class "A" concrete mix, what are the actual batch weights?

To determine the correct batch weights for a 1 cubic meter Class "A" concrete mix, it is important to recognize the typical proportions of materials used in such a mix. Class "A" concrete generally consists of a specific blend of cement, fine aggregates (such as sand), coarse aggregates (such as gravel or crushed stone), and water, which ensures the desired strength and durability.

For a Class "A" concrete mix, the batch weights often include approximately 360 kg of cement, 585 kg of fine aggregates, 1035 kg of coarse aggregates, and around 130 liters of water. These proportions are calculated based on achieving a balance that meets strength specifications while ensuring workability.

Each of the other options varies significantly from these accepted norms. For instance, providing too many bags of cement or not enough fine aggregates can lead to issues with the mix's strength or stability. Therefore, option A presents a combination of weights that reflects a practical and standard blend for producing Class "A" concrete in compliance with typical engineering requirements. This structured approach to batching is vital for ensuring consistency and quality in concrete production.
