INFLUENCE OF COARSE AGGREGATE SHAPE ON THE

Aggregates can be classified in many ways Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here Nov 29 This is the 3rd chapter from a famous book of concrete technology MS SHETTY As aggregate is the major part of concrete i thought it to share The objectives of this paper are to evaluate aggregate characteristics including elongation flatness and other shape indic The following particle shapes were

Analysis of Aggregate Shape Characteristics and its

Shape of three dimensional irregular bodies as coarse aggregate is difficult to describe but is the vital property affecting the workability of fresh concrete and Using larger coarse aggregate typically lowers the cost of a concrete mix by size of coarse aggregate that can be used in a mix depends on the size shape aggregates based on their shape angularity and texture characteristics This methodology utilizes the Aggregate Imaging System AIMS to measure aggregate
