Concrete is a plethora of building material available in many colours and textures. It is also able to be combined with other materials like sand or gravel to create distinctive designs. Concrete is used most often for walls, floors and countertops.
The concrete slab will be laid on top of the frame of steel. In terms of thickness, the thickness will depend on the dimensions of the project as well as the kind of flooring to be installed. For instance, a 6 inch thick slab will be sufficient for a 12×24 foot space.
1.Concrete Screed Mix
Mixes of concrete screed are utilized to construct concrete driveways, patios, walkways and so on. The Concrete screed mix can be described as a mix consisting of cement, sand, water, and occasionally additives. The mixes are usually called “ready mixed” because they do not require mixing after being it is poured. There are a variety of concrete screed mixes each with its own distinct characteristic.
2.Sand
Sand is the primary material in any screed mixture made of concrete. Sand is made up of small particles, which are held together with air pockets. Sand is the least expensive ingredient in a concrete screed mix which makes it the most plentiful ingredient. It is the tiniest of the components in the concrete screed mix which means it occupies the most space within the container. Sand is considered to be inert, meaning that it doesn’t interact chemically with any other substances. Sand is also safe, non-toxic and biodegradable.
3.Cement
Cement is the second-highest ingredient in the concrete screeding mix. Cement is made up of clay, limestone, aluminum silicate, iron oxide and sulfur. When mixed, these components get harder over time and eventually turn into a solid. Cement is the most costly ingredient in the concrete screding mix. The cement is also among the largest component in the concrete written mix.

Water
Water is the third most plentiful ingredient in the screed mix. Water is required for cement to solidify and to bind the sand particles. It is also used to transfer the cement to its place of use.
-
Additives
Additives are chemicals that are added to a concrete screed mix to alter their physical property of the final product. Common additives are accelerators, thickeners, retarders, and stabilizers. Accelerators accelerate the process of setting, retarders can slow the process of setting. Thickeners improve the viscosity of the concrete, and stabilizers stop the formation of cracks within the concrete.
