Polymer concrete is a type of concrete that uses a polymer to replace lime-type cements as a binder. One specific type is epoxy granite , where the polymer used is exclusively epoxy . In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [ 1 ]
Humus has a characteristic black or dark brown color and is an accumulation of organic carbon. Besides the three major soil horizons of (A) surface/topsoil, (B) subsoil, and (C) substratum, some soils have an organic horizon (O) on the very surface. Hard bedrock (R) is not in a strict sense soil.
Plastic may be used in flooring and roofing materials. Doors, window panels, and skylights may be made of plastic. Washers, nuts, bolts, and other hardware might be made of plastic. Insulating materials are often made of plastic. Plastic can be used to build temporary and portable structures, such as tents and sheds.
Typical engineered composite materials are made up of a binding agent forming the matrix and a filler material (particulates or fibres) giving substance, e.g.: Concrete , reinforced concrete and masonry with cement, lime or mortar (which is itself a composite material) as a binder
The w/c ratio of concrete is one of the main parameter controlling the mechanical strength of hardened concrete and its durability. The same wood pulping process can also be applied to obtain humus-like substances by hydrolysis and oxidation. A kind of artificial "lignohumate" can be directly produced from wood in this way. [37]
Plastic consumption uses by field. Filler materials are particles added to binders (resin, thermoplastics, cement) to make a composite material. Filler materials improve specific properties or make the product cheaper. [1] Coarse filler materials such as construction aggregate and rebar are used in the building industry to make plaster, mortar ...
However, high value applications have started to receive more attention, notably the use of humins in the preparation of catalytic materials [11] and in material applications (e.g. plastic reinforcement and construction materials).
Initially, it was used in the Netherlands for filling voids and for ground stabilisation. Further research carried out in the Netherlands helped bring about the more widespread use of foam concrete as a building material. [6] More recently, foam concrete is being made with a continuous foam generator. The foam is produced by agitating a foaming ...
