Also the fine aggregate used in M20 concrete mix ratio is completely replaced by use of quarry dust which is a cheaper material when compared to sand. Ratio of fine and coarse aggregates replacement are prepared and accordingly the cubes are casted as per IS:456-2000 M20 mix ratio. Then ...
Suitability of Foamed Concrete for the Composite Floor System in Mid-to-High-Rise Modular Buildings: Design, Structural, and Sustainability Perspectives This study investigates the application of lightweight foamed concrete (FC) in modular building floor systems to address challenges in lifting and trans...

A device for use in the manufacture of lightweight concrete includes a first end having a reduced diameter portion for connection to a water supply line, an opposite second discharge end, and a cylindrical body between the first and seco... ...
Two mixes with w/c ratio were considered within the investigation workability test i.e. slump flow for M20 grade of concrete were conducted on the fresh concrete whereas compressive strength were evaluated to see the properties of hardened concrete.Hardik S. Mistri...
Using 40 mm size graded angular aggregate and zone II river sand, nominal mix concrete (1.0 : 1.5 : 3.0) was prepared. Density and cement content of fresh concrete were 23.45 kN/m3 and 390.83 kg/m3 respectively. Using same ingredients, nominal mix concrete was prepared using ratio given in...

Typically pervious concrete has water to cementisious material ratio of 0.28 to 0.4.The mixture is composed of cementisious materials, coarse aggregates and water with little to no fine aggregates. Addition of a small amount of fine aggregates will generally reduce the void content and increase...
in this present research work the steel fibers of diameter 0.6 mm and length 45mm was used with varying percentages of steel fibers of 0%,0.5 %, 1 % ,1.5 % ,2 % ,2.5 % & 3 % by the weight of concrete of M20 grade with water cement ratio 0.42 As per the present research ...
