Impact of COVID19 on the Global Construction Aggregates Market The construction aggregates market has witnessed a negative impact on the product demand in recent months owing to the lockdowns imposed in the majority of the countries due to the outbreak of COVID19 in December 2019Get Price
The need for impact value test is to find out the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading Find out the impact resistance of aggregate is important because during service life the aggregates will beGet Price

The impact value test is a type of quality control test for highway pavements and is used to check the suitability of aggregates to be used in the construction of highway pavements The property by which the aggregates are capable of resisting the impact is known as toughnessGet Price
Procedure of Aggregate Impact value test The test sample normally aggregates sized 100 mm to 125 mm the aggregates should be dried by heating at 100110 0C for a period of 4 hours and cooled Sieve the material through 125mm and 100 mm IS sieves The aggregates passing through 125 mm sieve comprises the test materialGet Price
Variation in the size of Aggregates changes the water demand cement content microcracking strength in concrete It also effects pumpability and durability of concrete Grading of aggregates depends on the proportions of coarse and fine aggregate If grading of aggregate is varied it also changes cement paste content cost economy workability of the mixGet Price
Increasing the maximum aggregate size and thereby the aggregate content by 20 per cent of the total volume of the concrete will ensure a substantial decrease in shrinkage The shrinkage of aggregates themselves may be of considerable importance in determining the shrinkage of concrete some finegrained sandstones slate basalt trap rock andGet Price
