2 Concrete structures are likely to bear tensile loads even if they do not have weight suspended directly from them. Consider a horizontal concrete beam spanning two vertical supports that hold it up from below. If a weight is placed on top of the beam, say halfway between the supports, the beam will bend (though perhaps imperceptibly) into a U

products. Ready-mixed concrete is the fluid form of concrete delivered to construc-tion sites in the familiar barrel-backed mixer trucks (not "cement" trucks!) and poured into a desired shape. Precast or prefabricated concrete products, like block, brick, pipe, and reinforced structural members, are instead made by

Additionally, even if you have a single shaft concrete mixer in the form of a horizontal unit, the speed is going to be relatively similar. It is the design of these concrete mixers that makes them faster, and that's why many people are changing over from the traditional vertical models to these horizontal concrete mixers with dual shafts.

When the planar specimen is tilted around an axis parallel to the image horizontal, the projection situation changes. The projection of the scan line on the projection plane intercepts the expected length of specimen parallel to the tilt axis, but perpendicular to the tilt axis and greater length of the specimen is projected into the same

3. Concrete is a porous material that contains air. When the temperature of the concrete rises, the air expands. This phenomenon, outgassing, may produce pinholes or blisters in primers and topcoat systems. To reduce the risk of pinholes from outgassing, apply PolyPrime Epoxy Primer and topcoat when the concrete temperature is stable or dropping.

prone to fail in a horizontal sliding shear mode, where the bottom flange tends to slide in against the bottom flange-web interface. Due to the increased flange width to web width ratio of the new Tx girders, there is reason to think that the horizontal sliding shear mode can govern the behavior of the Tx girders, compromising the
