FEATURES
A Night in the Life of a Concrete Pour Features A Night in the Life of a Concrete Pour

It's 11:30 p.m. in Sebastopol, Calif. Steve Beasely, owner of Bay Cities Concrete Pumping, fires up his 42-meter concrete boom. The engine roars through the late night stillness of his equipment yard. Steve is preparing for a 660 cubic yard slab pour in Rohnert Park at a new Ashley Furniture store. Shaking off his desire to go to bed, Steve shovels some blend sand in the back of the hopper, checks his oil and fuel levels, and inspects his hydraulics and boom pipe. It's pitch black out, save for the headlights on his Schwing boom pump. He'd like to read the paper or maybe have a cup of coffee but he has to hurry; he's got two pumps scheduled and concrete coming at 1 a.m. Read more

Material Incompatibility Features Material Incompatibility

Today's concrete mixes are more complex than ever, combining a wider range of cements, supplementary cementitious materials (SCM), and chemical admixtures to produce economical concretes that can meet exacting performance requirements.

Among the more common problems that result are premature stiffening, excessive cracking, and poor air-void systems. Read more
