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

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

The M3 would take a lot of the positive aspects of the M2 and expand upon them‚ to the effect that our British allies would request support from America before we had officially entered the war. Over 4500 M3s would be produced with several different variants each having increased performance‚ armor or other mechanical advancements. Some of
