This means that our water/cement ratio has been significantly altered: from 0.45 to 0.473-0.52. And that, my friends, directly affects the strength of the concrete, which has gone from having 30 N/mm2 to having 24.8 N/mm2 – or a 17% decrease in its compressive strength at 28 days (check out the graph at the bottom of this blog post for further reference).

Jag har tittat på några videoklipp som visar blandning av murbruk och cement och ett Not all of the water that is added to the concrete mix is necessary for the 

0.7 w/c ratio is also used for pumped concrete. 0.5 w/c ratio indicates, that for every 100 kg of cement, 50 lit. of water is added. 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 Roughly 1.1 unit volumes of water are required to completely hydrate 1 unit volume of cement, meaning that 1 cubic foot of cement will produce 2.1 cubic feet of hydration product formed from the available cement and water. This translates to a w/c ratio of 0.36. By Jay Shilstone. The specifier may require a water/cementitious materials ratio (w/cm) lower than that needed to produce the design strength.

Water Cement Ratio means the ratio between the weight of water to the weight of cement used in the concrete mix. Normally water-cement ratio falls under 0.4 to 

Water-Cement Ratio is defined as the ratio of the weight of water to the weight of cement. Water/cement ratio as per IS 10262 (2009) for the concrete mix varies from 0.4 to 0.6. 0.7 w/c ratio is also used for pumped concrete. 0.5 w/c ratio indicates, that for every 100 kg of cement, 50 lit. of water is added. The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. The most important factor determining the strength of concrete is the water to cement ratio.
