Sub-grade: the material at formation level after excavating or infilling; 2. Sub-base: selected imported granular material to form a stable level surface on which to construct the slab. Where lean-mix concrete is not used the surface is normally blinded with sharp sand; 3. Slip membrane: se...

Slump is the measure of concrete consistency and fluidity. It shows the flow and overall workability of freshly mixed concrete. Simply put, the higher the slump, the wetter the mix. Four-inch (4”) slump is very common with normal weight concrete and is good for pumping. Slumps that are ...
A high-grade concrete mix is poured into form structure 26 and vibrated in suitable manner to insure a dense and strong body. The upper surface is screed in the usual manner, taking care to leave the protected recesses free of concrete. After the concrete is set and cured for a suitable ...

out from an inaugural field placement, Georgia-based MEGASLAB has extended the value proposition of its namesake concrete structure from abrasion resistance, high load capacity and minimal drying shrinkage characteristics to markedly lower carbon metrics when measured against conventional slabs on grade. ...
You’ll also find advice on concrete mix design and calculating the water-cement ratio. BUILD A HIGH QUALITY SLAB ON GRADEWhy build a high quality slab on grade is best answered with, "what happens when you don't!"If the concrete is out of level (greater than ¼" in 10') it ...
The best floor slab results come from a 4,000 psi mix and pouring the concrete as stiff as possible, use a water reducer if available, keep the vapor barrier under the slab, but also be sure to wet cure the slab for at least seven days. Finish the slab to screeds set to grade sho...
