Young''s modulus, or the Young modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.. Young''s modulus is named after the 19thcentury British scientist Thomas Young; but the concept was ...
The volume fracti on of coarse aggregate and its modulus of elasticity are the biggest contributors (other than w/cm) to the modulus of elasticity of concrete (Mehta) . Thus the modulus of elasticity of concrete can be increased by using a higher volume of coarse aggregate or by using coarse aggregate with a higher modulus of elasti city, as ...
The type of coarse aggregate also influences the modulus of elasticity of concrete. Weaker aggregates tend to produce a more ductile concrete than stronger aggregates do. View

A set of high performance concrete mixes, of low water cement ratio and fixed mortar composition, containing six different types of aggregates of constant volume fraction, has been used to check moduli of elasticity at 7, 28 and 91 dayshe results have shown that, apart from the aggregates of very low and very high modulus, concrete modulus at ...
Nov 30, 2014· The dependence of the elastic modulus of the mixture and the composition ratio of the mixture (aggregates, bitumen, voids in mix) has been already proved in different researches . If the bituminous mixture has a low dynamic elastic modulus, below 10 MPa, or the mixture is subjected to high temperatures and/or long periods of application of load ...
Elastic Modulus Limits For Crushed Li Nein Sudan KNOCK. Elastic modulus limits for crushed limestone elastic modulus limits for crushed limestone relationship between compressive strength and modulus of modulus of elasticity of concrete is a key factor for estimating the around 05 to around 03 as selecting a crusher by compressive strength of the crushed.
The mineral makeup of the aggregate also influences the modulus of elasticity of concrete. In a study by Aitcin and Mehta, they tested four different types of aggregates: diabase, limestone, gravel, and granite. Their test results showed that the limestone and diabase aggregates gave the highest values for the elastic modulus. The gravel ...
Typical Soil Elastic Modulus (Young''s Modulus) Values. More Properties. Notation and Units. Metric and Imperial Units. The above values have been provided with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout.
Typical Values of Young''s Elastic Modulus and Poisson''s Ratio for Pavement Materials
Dec 27, 2016· The granite concrete had the highest elastic modulus at all temperatures followed by quartzite and limestone concrete. A linear fit to the data indicated that the modulus of elasticity of limestone, quartzite and granite concrete decreased,, and GPa, respectively, for every 100 °C increase in temperature.
Modulus of Subgrade Reaction Which One Should be Used? By Wayne W. Walker, , and Jerry A. Holland,, The modulus of subgrade reaction is an often misunderstood and misused concept for the thickness design of slabsonground. Terzaghi in 1955 (Ref. 1, P. 300) attributed this confusion to the initial work by Hayashi in
Elastic modulus of lightweight concrete with PVC aggregate was studied by Kou et al. (2009). Their results indicate that elastic modulus is reduced with an increase in PVC content. The 28day elastic modulus were reduced by %, %, %, and % for PVC aggregate content of 5%, 15%, 30%, and 45%, respectively. This elastic modulus ...
