Proportioning Concrete Mixes

Proceedings from a combined "paper symposium" and "workshop session" on concrete proportioning technology held at an ACI annual convention. Nine papers presented at the paper symposium deal with proportioning techniques and technology for application in pumping concrete, gapgraded aggregate concrete, mass concrete, proportioning with admixtures, fIy ash, and other pozzolans, and high strength concrete. Four papers from the workshop session cover history of proportioning, normal weight concrete, and no slump concrete.
