Which one is better for surface course? The abrasion value found from Los Angeles test for two aggregates A and B are 50% and 38% respectively. Which aggregate is harder? Why? For what types of constructions are these suitable?
WhatsAppعرض المزيدWet Aggregates WEAKENING AND DISINTEGRA nON BY WETTING The wetting process can be highly disruptive. Ion hydration and os motic swelling forces pull water in between clay platelets, pushing them apart and causing swelling of the aggregates in which they are incorporated. If an aggregate is wetted quickly, the wetted portion can swell appreciably compared to the dry portion
WhatsAppعرض المزيد· Potentially equally damaging is a condition when the aggregates are only partially saturated, with the moisture content below their absorption value. While this will potentially increase strengths and even durability if not accounted for, placing these dry aggregates into the wet concrete mixture will allow the aggregates to take up water from the paste, filling their pore spaces but

WhatsAppعرض المزيد· The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact. The impact value of an aggregate is sometime used as an alternative to its crushing value. Abrasion Value of Aggregates. The abrasion value gives a relative measure of resistance of an aggregate to wear when it is rotated in a cylinder along with some abrasive charge.
