How to Convert u-value to r-value?
To convert U vals To R Vals 1/u = r val
How many meters are there in 120mm?
120 millimeters = 0.12 meters
What is the R-value of Normal Weight Concrete per inch of material?
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
What has the highest R Value Concrete or Stucco or fiberglass insulation?
fiberglass
Which material has the highest r value stucco pine board concrete or fiber glass insulation?
Fiberglass Insulation, R Value of 3.14. Pine board has an R Value of 1.74
How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
To provide the same insulation value as 3.5 inches of fiberglass, a concrete wall would need to be approximately 15-18 inches thick. Concrete is a poor insulator compared to fiberglass, so a much thicker wall is needed to achieve similar insulation properties. Alternatively, adding insulation material within the concrete wall can help improve its insulating capabilities.
What is the slenderness ratio for a intermediate concrete column?

What are required slump height for different concrete structure?
M25 = 80 to 110mm in slab & beam M30 = 80 to 120mm in column
What is 120mm into km?
120mm = 0.00012km
Does concrete have an R value. 8 inches is equal to about a single pane of glass. Not much at all...?
Yes. Don't know for sure but its pretty low. however note that R value depends on the thickness. You double the thickness you double the R value.
What is the R value of concrete?
The R value of a material is the thermal resistance of the material, so is dependent on the material's thickness. R is also the inverse of a material's thermal conductivity U. To work it out you need the k value ( the thermal conductivity) of the material and the thickness, then R=thickness/k. The k value for structural concrete (of density 2300kg/m3) is 1.6 W/mK (Units: Watts / (metre x degrees Kelvin) so for a thickness 100mm (0.1m) of this concrete, R=0.06 m2°C/W. Note that the R value in imperial units will not be the same. Check the units for any R value of any material that is given.
What is the best insulation for concrete basement walls?
The best insulation for concrete basement walls is rigid foam insulation. It provides high R-value, moisture resistance, and is easy to install.
What must be the slump value for different grade of concrete?
what is the slump value for M20 concrete
What has the author R J Currie written?
R. J. Currie has written: 'Carbonation depths in structural-quality concrete' -- subject(s): Concrete, Concrete construction
