Mix Proportion designations The common method of expressing the proportions of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregates. For e.g., a concrete mix of proportions 124 means that cement, fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement, two parts ...
Concrete Mix Ratio What Is Concrete Mix Ratio Types Of
What Is Concrete Mix Ratio Making concrete, it is important to use the correct concrete mixing ratios to produce a tough, long life, durable concrete mix. To make concrete, four basic materials you need Cement, sand, aggregate, water, and add-mixture.. This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.
