Mixing Concrete for the Beginning DIYer

In either case, be it in a bucket, a wheelbarrow, or a cement mixer, the mixing ratios remain the same. If you should find that your project requires more concrete than the ratios outlined in this article, simply increase the number of buckets of material you mix in proportion to the mixing ratio. For example: if you use two buckets of Portland ...

Mechanical Behavior of Recycled Fine Aggregate Concrete with

Five replacement ratios (i.e., 0%, 15%, 30%, 50%, and 100% by weight) were selected, resulting in a total of ten mixing proportions (see Table 3). Notably, concrete with zero replacement ratio of RFA, referred to as virgin concrete, provides the reference mechanical behaviors. The specimen IDs indicate the design strength and RFA replacement ratio.

Effect of W/C Ratio on Durability and Porosity in Cement

Water is often added to concrete placing for easy workability and finishability in construction site. The additional mixing water can help easy mixing and workability but causes increased porosity, which yields degradation of durability and structural performances. In this paper, cement mortar samples with 0.45 of W/C (water to cement) ratio are prepared for control case and durability ...

How to Calculate the Water to Cement Ratio

(Table 19-A-2) Use a maximum .45 water to cement ratio for concrete with severe or very severe sulfate conditions per the 1997 Uniform Building Code (Table 19-A-4) Water permeability increases exponentially when concrete has a water cement ratio greater than .50. Durability increases the less permeable the concrete mix is.
