Mm=Weight of the empty concrete measure (base of air meter) Vm=Volume of the measure (usually about 0.25 ft3for a pressure meter base) (Fig. 3) Testing tip:Having the unit weight data gives you "a third point to check a straight line." For example, when slump increases, the air con...

Precast concrete block used to build walls. It has hollow cores that can be filled with concrete onsite for additional reinforcement. The use of stronger, more lightweight types of concrete such as autoclaved aerated concrete is popular in the manufacture of these units. ...
In this study, a generalized equivalent Stress Block Model has been proposed that is applicable to all types of concrete, including lightweight and high-strength concrete (HSC). First, available stress-strain models for concrete were verified through an extensive database. Then, the coefficients us...
