Concrete Mix Design Calculations
concrete mix decreases.concrete mix decreases. • As the surface area of the aggregate increases the more water will be needed to maintain a given slump. • Coarser Surface Texture • Particle Shape • Particle Size Distribution • As the air content increas es, the strength of the concrete decreases. 4 • It's a calculation:
Cast iron directly on concrete raises moisture and rust concerns
Jamie, there should be no chemical reactions between cast iron and concrete. If your vapor barrier and water management strategy are good, your slab should be dry, once the construction moisture is out. But if the house is new, the slab will continue to evaporate moisture for up to a year or so. If you're in a cold climate and don't have good ...

Leave 6-12 inches of space around the forms so that you can set the supporting concrete. Step 3: Pouring the Concrete This comes in two steps. One, you have to set the concrete around the tops of the support forms. This will create an even surface around the trench opening. Allow it time to dry properly before moving onto the trench itself.
