In this article we will discuss about:- 1. Introduction to Workability of Fresh Concrete 2. Factors Affecting the Workability of Fresh Concrete 3. Measuring the Workability 4. Effect 5. Segregation 6. Bleeding. Introduction to Workability of Fresh Concrete: The strength of concrete of a given proportion is affected very much by the degree of its compaction. Therefore it is desirable [...]
Usually the tests that can be adopted to determine the workability of concrete are: 1. Slump Test 2. K. Slump Test 3. Kelly Ball Test 4. Compacting Factor Test 5. Flow Test. 1. Slump Test: This test is used extensively at the site of Work all over the world. Actually this test does not measure the workability of concrete but [...]
Following factors that have been found affecting the workability of concrete: 1. Type of Super Plasticizer 2. Dosage 3. Mix Composition 4. Variation in Cement Composition and Properties 5. Mixing Procedure 6. Equipment 7. Others. Factor # 1. Type of Super Plasticizer: It has been well established that efficiency of a super plasticizer is the function of its molecular weight [...]
