Get PriceThe two different ways in Concrete Proportioning Mixture: 1. Volume Method. 2. by Using Mixturing Box. Volume Method is the most common and convenient method in Mixing Concrete to attained the desired strength of concrete.Concrete misture it involves cement sand and gravel.
Get PriceConcrete with a PSI rating of 6000 or more is considered high-strength concrete. It is typically found in nuclear power plants and other areas where radiation contamination is possible. High strength concrete has a lower water-cement ratio giving it additional durability and strength.

Get PriceMix all ingredients for 5 minutes to blend the water. Allow the concrete to sit for 3 minutes after this initial mixing so that the water has a chance to penetrate all of the ingredients. Mix the ingredients for another 5 minutes and then you are done. You have now made ultra high performance concrete with strength of approximately 30000 psi.
Get PriceThe ratio between the water weight to the cement weight is known as the water-cement ratio or W/C Ratio. Role of Water in Concrete or Cement Mortar As you all know concrete is a macro content which consists of Cement Sand and coarse aggregates.
Get PriceA concrete mix is to be designed for use in a 250 mm (10 inch) thick JPCP pavement. The desired properties are: Slump = 25 mm (1.0 inch) Average 28-day flexural strength of at least 4.5 MPa (650 psi); Coarse aggregate: nominal maximum size = 37.5 mm (1.5 inch) dry-rodded weight = 1600 kg/m 3 (100 lb/ft 3) specific gravity = 2.68 moisture content = 1.0 percent absorption = 0.5 percent
Get PriceThe amount of water added to concrete is called the water/cement ratio. Though adding more water to the concrete will make it easier to mix pour and work with it actually lowers the concrete strength of the concrete when cured.
