Consturction Material EGC 1131 Assignment 1 Question 1 (a) A significant tendency for large and fine particles in a concrete mix‚ separate among each others. Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over

structures are in structural concrete. The functional demands of such high rise structures include the use of durable materials. High Strength Concrete‚ Self–compacting Concrete are gaining widespread acceptance. Apart from the basic structural materials‚ modern projects require a variety of secondary materials for a variety of purposes such as construction chemicals‚ waterproofing materials‚ durability aids etc. The paper highlights some of the recent developments.
