Tests Performed There are following tests which will be performed to find out the properties of fine aggregate and coarse aggregate. Fine Aggregate Tests Fine aggregate in concrete is sand which work as a filler material in concrete because it contains fine particles which fills the gaps and results in void reduction. There are following tests which will be performed to check out the properties of fine aggregate. Bulk Density Test for Fine Aggregate Scope By the help of this test bulk density of aggregate in a compacted or loose condition and voids between particles of Fine, Coarse and mixed aggregates is determined. Significance and Use This test will be used to determine the bulk density of fine aggregates which is necessary for many methods…show more content…
Scope The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design, production control requirements, and verification specifications. Accurate determination of material passing the No. 200 (75 µm) sieve cannot be made with this test alone. Significance and Use We will use this method to determine the particle size distribution of mineral fillers, coarse and fine aggregates for Portland cement concrete. A gradation curve or chart showing how evenly or unevenly the sizes are distributed between largest and smallest is created in this test. How an aggregate is graded has a major impact on the strength of the base or on the properties and performance of concrete. Coarse Aggregate Tests Coarse aggregate in concrete is crush which is used to develop strength of concrete. Coarse aggregates are those which retains on #4 sieve. There are following tests which will be performed to check out the properties of coarse aggregate. Bulk Density Test for Coarse…show more content…
Significance and Use Water absorption values are used to calculate change in mass due to water absorbed in the pores spaces of constituent particles compared to dry condition. This method is suitable for the determination of water absorption of the aggregates that have conditioning other than 15-hour soak such as boiling water. The pores in lightweight aggregate may or may not fill with water after immersion of 15-hour soaking period. Therefore, this method is not suitable for the use of lightweight aggregate. Fineness Modulus for Coarse aggregate Scope Fineness modulus of coarse aggregate represents the average size of the particles in the coarse aggregate by an index number, it is calculated by performing sieve analysis with standard sieves. Significance and Use The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of coarse aggregate. Higher the aggregate size higher the fineness modulus hence fineness modulus of coarse aggregate is higher than fine. Fineness modulus is the number at which
