View MoreContrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. applications of aggregate crushing test itthe aggregate crushing value is an indirect measure of crushing strength of the aggregates. low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. hus the test can .
View More0the aggregate dry density was the highest in cna, followed by cra-1 and cra-2. thus, pc and sc allow obtaining aggregates with less adhered mortar, making the absorption and abrasion wear of cra-1 lower than that of cra-2. regardless of the quality of the bonded paste and type of crushing, about 85 of cra absorption occurred in the initial ...
View MoreThe recycled coarse aggregate has an aggregate crushing value acv and an aggregate impact value aiv of 24.5 and 5.28, respectively compared to 15.4 and 1.67 of the na. this implies that the crushing and impact values of rca are low, and it is because the adhered mortar on rca has a low tendency to resist impact and abrasion loadings.
View MoreThe aim of this paper was to examine the feasibility of using nanoparticles of sio 2 nanosilica to improve the performance of recycled aggregate concrete rac containing recycled aggregate ra derived from processing construction and demolition waste of concrete buildings. the examined properties include compressive strength, splitting tensile strength, and water absorption.
