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.
