In this research, grinding energy of selected rock samples collected from South West Nigeria was determined using comminution theory in order to evaluate suitability of rock for aggregate production. Bond Work Index (BWi), Aggregate Impact Value (AIV) and Aggregate Crushing Value (ACV) of samples was characterized and correlated.Jul 18, 2021 Determine the aggregate crushing value of coarse aggregate 2. Check the suitability of coarse aggregates to use in different types of road. Apparatus Required for Crushing value test. 1. A balance should be accurate up to 1 gm 2. IS sieves of size 12.5 mm, 10 mm, and 2.36 mm 3. Mould, measuring cylinder with plunger and base plate.Further , the aggregate crushing value, flakiness index and water absorption factor of 23.8, 24.1 and 0.38 respectively, do not exceed the corresponding values of 30, 35 and 0.5 respectively, provided for in the FMWH, 1997, specification (Clause 6371, Table VI-13). The aggregates are therefore of the quality required 3.3 Aggregate Gradation.

Itaogbolu, Ondo State, Nigeria is porphyritic granite (tagged as PG2) Itaji-Ekiti, Ekiti State, Nigeria is granite gneiss, and Akure, Ondo State, Nigeria is charnockite rock 2.3 DETERMINATION OF AGGREGATE CRUSHING VALUE The Aggregate Crushing Value (ACV) was determined using the standard procedure suggested in BS 812-110.Oct 01, 2016 The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Also read Crushing Value Test of Aggregates. 13. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact.The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure. Cylinder, plunger and base plate are made from special alloy.Click on the cylinder to transfer the aggregate into 2.36mm sieve. Once the aggregate is added into sieves click on the set of sieves to place it in the mechanial shaker. Calculate the weight of aggregate retained on pan, click on NEXT button to proceed. Calculate the average aggregate crushing value, click on CHECK button to evaluate the answer.

Nigerian the aggregate impact value (AIV) and aggregate crushing value (ACV) are used in scrutinizing aggregates to determine their suitability for use in road constructional work. The ACV test which is prescribed for strong and hard aggregates according to the BS 812, part 110(1990) is a relative measure of the resistance of.Nigeria 180TPH Granite Crushing Plant . 100-120TPH Limestone Tailing Crushing Plant . 130--200TPH Building Waste Crushing Plant . Sri Lanka 50TPH Hard Aggregate Crushing Plant . Myanmar 120TPH Granite Crushing Plant . Thailand 1000TPD Iron Ore Crushing Plant .The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact. Due to traffic loads, the aggregate are subjected to the pounding action.Aggregate crushing value apparatus 75 mm. BS 812 110. Comprising 75 mm nominal diameter steel cylinder, plunger, base plate, tamping rod and measure 57 mm diameter x 90 mm deep. Used for aggregate smaller than 9.52 mm. The complete assembly is cadmium plated for corrosion protection. Weight 8 Kg.

May 17, 2019 Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are.The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines.Aggregate crushing value apparatus (ACV) ( Aggregates-Rocks ) Comparable to BS 812 110. Two models available A082 Comprising 150 mm nominal diameter steel cylinder, plunger, base plate, tamping rod and measure 115 mm diameter x 180 mm deep. Used for aggregate passing 12.7 mm and retained by 9.52 mm sieve.The apparatus of the aggregate crushing value test as per IS 2386 (Part IV) – 1963 consists of 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod of circular cross-section 16mm diameter and 45 to 60.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.According to Shetty [3], the aggregate crushing value and the aggregate impact value should not be than 45 for aggregates used for concrete other than for wearing surfaces, and 30 for concrete used for wearing surfaces such as runways, roads and air field pavements. Concrete production in Nigeria are largely carried out.Aggregate crushing value indicates strong aggregates, as the crushed fraction is low. ~hus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components. The aggregates used for the surface course of pavements should be strong enough.The results of the study revealed that its specific gravity, bulk density, porosity, water absorption, silt content, the impact value and the aggregate crushing value showed satisfactory performance. The percentage replacement of natural river sand with quarry sand for a designed strength of 25N mm 2 varied at intervals of 10 up to a maximum.
