Sometimes when your calcium/magnesium ratio is off, you can get twitching. I get one in my diaphram that feels like a fish flopping in my chest. If you are low in calcium intake, or very low in magnesium, the muscles do a dance of sorts. So you could try to balance that out.
(February 2017) A concrete slab is a common structural element of modern buildings. Horizontal slabs of steel reinforced concrete, typically between 4 and 20 inches (100 and 500 millimeters) thick, are most often used to construct floors and ceilings, while thinner slabs are also used for exterior paving.
Monolithic slab is a term used in concrete slab construction to describe concrete structural elements such as footings, slabs, foundations, grade beams, piers, and columns being poured simultaneously. A monolithic cement slab or diy concrete slab not only applies to concrete cast on the ground, it also applies to suspended slab. Even though a suspended concrete slab is above ground level, the use of shoring materials enables the pouring concrete slab monolithically with concrete beams and columns.
