AbstractThis Research paper is a live study on the above mentioned title Recycling of Concrete This paper consist the introduction of recycled concrete aggregate with its uses and properties. Various test results on Recycled concrete aggregate also described. It also consist the difference between RCA and natural aggregate.
Concrete Sampling. Concrete cubes are made on site to check that the strength of the concrete is above the minimum strength which has been specified. Standards. BS EN 123501:2000 Testing fresh concrete. Sampling. BS :1983 Testing concrete. Method for making test cubes from fresh concrete.
The results of this test method are used as a basis for quality control of concrete. A testing machine, capable of providing the load rates as prescribed in the standard should be equipped with two steel bearing blocks, one of which is a spherically seated block that will bear on the upper surface of the specimen, and the other a solid block on ...
Mechanical Properties of Aggregates 10% Fines Value Test (BS:812, part 3) Procedure • In this test, the apparatus of the standard crushing test is used to determine the load required to produce 10% fines from the to mm particles. • This is achieved by applying a progressively increasing load on the plunger so as to cause its penetration in 10 minutes of about: 15 mm for rounded ...
Methylene Blue Test Set. Durability and Abrasion equipment measures the hardness, strength and durability properties of aggregates. Sulfate Soundness, Los Angeles Abrasion Machine and MicroDeval tests are some of the popular methods used to analyze properties such as resistance to wear, susceptibility to freezethaw damage and overall aggregate strength.
The main purpose of adding sand in concrete is to minimise the segregation of concrete and to fill out the pores between the cement and coarse aggregate. This test (bulking of sand or bulking of fine aggregate) is to ensure that we are using the right amount of sand while concreting.
