POLYMER CONCRETE


Polymer concrete

Polymer concrete is an ordinary concrete produced with OPC ( Ordinary portland cement) wet cured and inseminated with liquid or vaporous chemical compound (Methyl methacrylate monomer) and polymerized by gamma radiation or with chemical initiated implies, i.e by utilizing thermal catalytic method (Adding 3% Benzoyl peroxide) to the monomer as a catalyst. The impregnation is helped by drying the concrete at an extreme temperature by evacuations and absorbing the monomer under limited pressure.


TYPES OF POLYMER CONCRETE:

Polymer concrete can be classified in following three categories:

1. Polymer impregnated concrete (PIC).

2. Polymer cement concrete (PCC).

3. Polymer concrete (PC).


ADVANTAGES OF POLYMER CONCRETE:

1. It has high impact resistance and high compressive strength.

2. Polymer concrete is highly resistant to freezing and thawing.

3. Highly resistant to chemical attack and abrasion.

4. Permeability is lower than other conventional concrete.

What are Eco-Friendly Products?



According to a definition given by the website all-recycling-facts.com, eco-friendly products are “products that do not harm the environment whether in their production, use or disposal”. In other words, these products help preserve the environment by significantly reducing the pollution they could produce. Eco-friendly products can be made from scratch, or from recycled materials. This kind of product is easily recognizable as it is, in most cases, labelled as such.

Some people think that it requires lot of time, effort and money to make a home eco-friendly. The truth is that there are lot of eco-products that you can start using right now which can help you to reduce waste and make this planet a better place to live. Eco-products are also known as environment friendly products or green products as they cause minimal harm to people and the environment.

Bio Plastics


These are plastics made from plants. The starch contained within the plant is processed to produce a polymer. It is actually possible to produce most polymers from bio materials, but the bio plastics London Bio Packaging uses most commonly are Ingeo™ PLA (Poly-Lactic Acid) and Mater-Bi®.

Bio-plastics behave in a similar way to conventional plastics and are suitable for most packaging applications. However, unlike finite oil based plastics which take millions of years to form and hundreds of years to degrade, they are annually renewable and suitable for commercial compost (nature’s way of recycling) within 12 weeks where facilities exist. The carbon footprint of Bio-plastic is therefore much lower than traditional petroleum based plastics. For examples, manufacturing Ingeo produces 60 percent less greenhouse gases and uses 50 percent less non-renewable energy than traditional plastics like PET
