WebLime concrete is composite mixture of lime as binding material, sand as fine aggregate and gravel as coarse aggregate in appropriate proportions. Lime concrete mix ratio depends on the type of construction, but in general, it can be taken up to 1:2 ratio for lime, sand respectively and up to 1:3 ratio for lime, coarse aggregate respectively. WebFor the design of earth retaining structural elements, the earth pressure will be determined as follows: Ka (active earth pressure) = 1sin / 1+sin = 0.33 (used for check of stability) Kp (passive earth pressure) = 1+sin / 1-sin = 3.0 Ko (at rest pressure) = 1-sin = 0.50 (used for design of section)

Webτ bd = Bond stress φ = Diameter of bar Ld is called the development length and As per code IS 456:2000, it is given by Ld = σ st φ/4τ bd This formula is used to calculate the required development length in mm for any given diameter of the bar. The same formula is used for the limit state method as well as the working stress method.
