Thin Concrete Floor Slab
Slab design must be checked for required additional reinforcement at penetrations.
Thin concrete floor slab. This type of mix is best for pouring a very thin coat of concrete such as when topping off or leveling out an existing slab. Typically a pro applies thin layers on an area like a walkway. The depth of the profile increases with the thickness of the. Consequently a reduction in concrete also decreases the gravity loads on the vertical load carrying.
One obvious advantage is less concrete is required. If you can remove the whole surface layer then use a latex self levelling compound to resurface the floor make sure the surface is wet before you apply the compound. The aggregate in a concrete mix is listed on the label. The thin mix is laid over the old concrete slipping into.
Overlays can be paper thin or several inches thick. Thin concrete overlay micro topping for floors and walls surecrete s micro topping is a single component thin concrete overlay that is a self bonding cement based for interior concrete surfaces. The thicker the material the stronger it is. Neglecting to prepare the old surface will prevent the new concrete from adhering correctly resulting in a weak bond between the two layers.
Preparation must create a surface profile free of bond inhibiting material. Thin concrete pavement tcp advanced concrete engineering for industrial pavements pna expands into the exterior space with new proprietary tools and technologies that optimize pavement designs reducing construction and maintenance costs while maximizing performance and service life. Fine aggregates are typically sand or crushed stone. This article will focus on applications inch thick and less.
Aggregates are additives that make up most of a concrete mix. As you have found a thin layer of screed on concrete breaks up like toffee. The thickness of the overlay defines the method of slab preparation. Even though a thinner layer is cheaper the cost to build a concrete walkway is largely determined by the size and length you prefer.
The thinnest a concrete slab can be is about 2 inches.
