The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. . strong, 10–20% Strong, 20–30% Satisfactory for road surfacing & > 35%Weak for road surfacing. 6.0 CONCLUSION Based on the experiments .
Impact value of an aggregate is the percentage loss pf weight of particles passing 2 sieve by the application on load by mean of 15 blows of standard hammer and drop under specified test condition. The aggregate impact value gives a relation measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs .
Aggregate Impact Value BSI BS 812-112 (1990c) . In conclusion, despite having used aggregates from . and eventually may supplant more tedious aggregate test methods. .
EXAMPLE FOR LAB REPORT laboratory aggregate impact value introduction aggregate impact value (aiv) is the percentage of fines produced from the aggregate sample . The test gives an idea of toughness of the aggregate to resist facture under the impact of moving loads. AIV below 10 are regarded as strong, and AIV’s above 35 would normally be . Round the result to the nearest whole number, and report the mean of two observations as the Aggregate Impact Value. What do the AIV values mean? Here are the recommended Aggregate Impact Test values and their corresponding classifications: Aggregate Impact Value Classification. Less than 20%: Exceptionally strong. Between 10% . Conclusion. In the construction industry, the Aggregate Impact Value test is a critical tool for assessing the quality and suitability of aggregates for road construction. It helps ensure that the materials used in building our roads possess the necessary toughness to withstand the impact of vehicular traffic, ultimately contributing to the .
The Los Angeles test is a measure of degradation of mineral aggregates of standard gradings resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness .In the Aggregate impact value test, a small portion of coarse aggregates having a size range between 10 to 12.5 mm, is confined in a 75 mm diameter cylindrical metal measure and subjected to 15 .
