Elastic Properties of Concrete Elasticity Creep and ShrinkageEstimating the Price Elasticity of Residential Water
Elasticity Creep and Shrinkage 327 In view of the peculiar and complex behaviour of stress strain relationship the modulus of elasticity of concrete is defined in somewhat arbitrary manner The modulus of elasticity of concrete is designated in various ways and they have been illustrated on the stress strain curve in Figure 82The estimate of price elasticity is close to that from the MDP model without the income effect Our mean estimate of the income elasticity of water demand is about showing that a 1 increase in median income between and increased water use by over that interval
