This article series tells how to mix your own concrete or how & when to decide to order a concrete delivery when building a deck, porch, or exterior stairs, pouring a floor slab, building a concrete foundation or other structure as well as how to handle concrete for small do-it-yourself...
I use 3500 psi concrete mixes for garage slabs that are used for heavier vehicles than your standard car or pickup truck. I also use it to pour all my floors when the weather starts getting colder. It has more cement per yard than a 3000 mix which helps it set-up faster. ...
and the beam adapted to receive at least one anchoring element such that the at least one anchoring element protrudes into the channel, wherein the at least one anchoring element is for engaging the concrete mix, such that once the concrete mix hardens, the at least one element contributes to...
For most interior slabs, the vapor barrier should be placed on top of the subbase before placing the concrete. The best way to know if the subbase is properly compacted and ready for the slab is by proof-rolling, which is running a heavily loaded truck (such as a fully loaded concrete...
Method and apparatus for constructing multi-storied concrete buildings Disclosed is a method and apparatus for extracting large form panels used in forming floor slabs on poured-in-place, multi-story concrete structures from beneath the slab they last formed. The preferred embodiment apparatus, called...
asphalt, liquid asphalt, is also introduced. The behavior ofasphalt concrete, which is mainly used for pavement, in actual environment is discussed. Its responses to applied loads, moisture, temperature, and chemicals are described in detail. Finally, themix designofasphalt concreteis briefly ...
A BEAM AND METHOD FOR REINFORCING CONCRETE SLABSA BEAM AND METHOD FOR REINFORCING CONCRETE SLABSA beam for reinforcing a concrete slab, the beam including a channel for receiving concrete mix therein, and the beam adapted to receive at least one anchoring element such that the at least one anch...
The extruder in accordance with the invention has an assembly of at least one contoured core section which performs a combined movement of oscillatory rotation and longitudinal reciprocation to generate inside the molding space a compacting shear action in the concrete mix. The extruder in accordance ...
This height is then measured; three to four inches are considered ideal, but a shorter slump may indicate too much water in the mix, which can weaken the concrete. Samples of fresh concrete taken from the chute of the delivery truck will be used to fill at least three cardboard or ...
