e) Compressive Strength (After 7 Days) Table 8 shows different compressive strength values at different aggregate cement ratios. Using this, graph between compressive strength and A/C ratio is shown in Fig.10. It is clear from the Fig.10 that as A/C ratio increases compressive strength of pervious concrete decreases.

Determination of water/cement-ratio of concrete

Water/cement-ratio (w/c-ratio) is an important factor affecting quality of the concrete, which has motivated engineers to do research on determining the w/c-ratio. The traditional way to estimate the w/c-ratio by weighing the cement and water from mix design. The estimated results are usually not

Compressive Strength of Concrete & Concrete Cubes | …

The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio, the higher is the compressive strength. The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI units.

Water–cement ratio - Wikipedia

The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm. Cementitious ...
