Durability Of Concrete Crusherin India

Exposure Conditions Affecting the Durability of Concrete 1. Exposure Conditions Based on IS 456. There are five levels of environmental exposure of concrete upon which the durability requirements of concrete are based. Mild, moderate, severe, very severe, and extreme exposure are different exposure categories established by the Indian standards based on the environment

Strength is an important property to be looked into before selecting stone as a building block. Indian standard code recommends, a minimum crushing strength of 3.5 N/mm 2 for any building block. Table 1 shows the crushing strength of various stones. Due to the non-uniformity of the material, usually, a factor of safety of 10 is used to find the

Feb 21, 2021 This article investigates the suitability of utilizing end of life rubber tyre particles in concrete as fine aggregate. Rubber ash and rubber fibers were used to develop two series of rubber ash concrete (series I) and hybrid concrete (series II) mixes. The natural fine aggregate was replaced by rubber ash (by volume of 5%, 10%, 15% and 20%) in series I; whereas in series II, the amount of
