Title: Comparison Of The Physical And Mechanical Properties Of Hand Rodded And Vibrated Concrete Made With Different Cements
Author(s): George W. Washa
Publication: Journal Proceedings
Appears on pages(s): 617-646
Abstract:Presents results of a comprehensive series of tests on vibrated and hand-rodded *concrete. The variables for each method of placement are five different mixes and five different cements. Particular attention has been paid to the lean mixes, the leanest vibrated mix being I :6:12 by weight, wrth only 2.2 sacks of ce- ment per cu d of concrete. The results obtained indi- cate the e ects of the variables on compressive ff strength, permeability, specific weight, absorption, linear changes due to alternate heating and water soaking, modulus of elasticity, Poisson’s ratio, shrink- age, and plastic flow.
