The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.Concept and significance of the Aggregate crushing value test.

The treated RCA with T1, T2, and T3 enhanced the concrete slump by 15%-35% compared to the untreated RCA. While the reduction in compressive strength for the untreated specimens was noticeable compared to the control specimens.

Calculation for Aggregate Crushing Value Test. In each test, the ratio of the weight of fines formed to the total sample weight shall be recorded as the percentage. Record the result to the first decimal place. Aggregate crushing value = (W 2 / (W 1 W 0 )) x 100. Where, W 0 = Weight of empty cylinder with base plate.The crushing value of aggregate could not surpass 45% for aggregate utilized for concrete other than for surfaces wearing, and 30 percent for the body of concrete used for surfaces wearing i.e(PDF) RELATIONSHIP BETWEEN AGGREGATE CRUSHING VALUE

The aggregate crushing value of coarse aggregates to be utilized for cement concrete pavement surface should not exceed 30%, according to the IRC and BIS. However, neither the IRC nor the Ministry of Road Transport and Highways have prescribed aggregate crushing values for coarse aggregates to be utilized in flexible The demand for virgin aggregates for concrete production worldwide has been increasing. At the same time, there is an increase in the production of rubbles from construction-related activities. The residues are produced either due to leftovers or from the demolished structures.

Crushing is one of the most energy-consuming technological processes. The purpose of grinding is to achieve the desired grain size of mineral raw materials. The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate bituminous concrete, a maximum value of 35 is specified. 8.3.3 Impact test The aggregate impact test is carried out to evaluate the resistance to impact Chapter 8 Pavement materials: Aggregates IIT Bombay

crushing value is defined by the percentage loss in mass on 2.36 mm size of test. Bigger percentage of aggregate crushing value means the aggregate is inferior in quality. According to BS 882:1992, aggregate with crushing value less than 25% can be used in heavy duty floor, crushing value for more than 30%, aggregate to be used in For cement concrete pavement surfaces, the coarse aggregates should have a crushing value of up to 30% and 45% for other than wearing surfaces as per IRC and BIS [IRC, 2011; IS: 2386 (Part IV), 2016]. For flexible and bituminous pavement, no aggregate crushing value is given for coarse aggregates by IRC or MORTH.Frontiers Sustainable usage of demolished concrete waste
