A 100-foot long concrete bridge deck (w/c = 0.40) had a shrinkage of 0.28-inches at 15 days and 0.75-inches after one year.  The shrinkage at one year was estimated to be 85% of the total shrinkage the bridge deck will see.  Please calculate the percent shrinkage of the bridge deck at 15 days, 1 year and the total shrinkage percent.  Do these values seem reasonable? Briefly explain why or why not.

Properties of materials

A property of a material describes its characteristics and distinguishes it from the others. The material properties are described it in terms of its hardness, color, appearances, and so on. The material properties generally depend on the type of material, or whether it is a metal or an alloy. There are different kinds of material properties such as mechanical properties, thermal properties, physical properties, and chemical properties. Chemical properties describe the material in terms of a chemical change. The mechanical properties come into existence when the material is acted upon by an external load. Thermal properties are associated with the temperature of the material and specific heat.
