A true composite, concrete typically consists of gravel and sand — aggregate — bound together in a matrix of fine Portland cement, with metal rebar usually incorporated for strength. It performs admirably under compression, but tends to be brittle and somewhat weak in tension.
Concrete is the most widely used man-made construction material. Concrete is a composite material consisting of four basic ingredients namely Cement, Fine aggregates (Sand), Coarse aggregates, and Water. In some cases, a fifth ingredient known as a chemical admixture is also added if necessary.
The good news is ® composite decking can be installed over concrete. While you can remove the concrete before putting in your composite deck, it’s often far more cost-effective to build the composite deck over the concrete if your concrete is in good condition. Some benefits to installing composite decking over concrete include:
Part 11 - Concrete as a Composite Material A composite material may be defined as a combination of at least two chemically and mechanically distinct materials with a definite interface separating the components; clearly concrete qualifies. This definition of a composite works on many levels.

Concrete is regarded as a composite material because it is composed of a number of materials that combine to form this versatile building material. Most concrete is made up of Portland Cement, aggregates (gravel, crushed stones) and sand. Water is added to the mix. Concrete can be purchased as precast products, such as paving stones.

They have a backer that will raise them slightly off the concrete. Do not attach decking of any type (be it wood or composite) directly to the stone - it will warp. Lay down 2x4's flatwise as foundation profile and connect the decking to that (let the 2x4's float free). This is essentially the same as the tile approach.
A slab is considered to be composite after the concrete has been adequately cured. Composite slabs are evaluated under the load combinations required by the applicable building code or by ASCE 7, Minimum Design Loads for Buildings and Other Structures, in the absence of a building code.
A composite material is any material made by combining two or more materials in a structure whereby materials remain separate. This is done to produce materials with desirable properties such as high compressive strength, tensile strength, flexibility and hardness.The following are illustrative examples.

Engineered cementitious composite (ECC) is a concrete material that attempts to embody the above aspirations. This material has been undergoing extensive research and development by an increasingly global community of researchers and industrial early adopters. Some highlights of the characteristics and functionalities of ECC are described below.

Concrete is by far the most versatile and most widely used construction material worldwide.
Concrete is the most common artificial composite material of all and typically consists of loose stones (aggregate) held with a matrix of cement. Concrete is an inexpensive material, and will not compress or shatter even under quite a large compressive force.

Cement based composite systems, consisting of fiber reinforced composites in form of fabric meshes and a cementitious bonding agent, recently, emerged as a very effective strengthening solution for existing reinforced concrete structures.
This journal is designed to reflect current developments and advances being made in the general field of cement-concrete composites technology and in the production, use, and performance of cement-based construction materials.The word cement is interpreted in a wide sense, including not only Portland cement but also blended cements and other binding materials.
