Why do they put polystyrene in concrete?
Why do they put polystyrene in concrete?
They reduce the effects of soil movement, decrease the amount of concrete required, and have thermal insular properties making them a cost effective component for any home, building or complex. In traditional slabs, the bottom of the slab uses footings based on concrete beams which require extensive digging.
What is polystyrene used for in construction?
Major applications of EPS include, insulated panel systems for use in floors, walls and roofs of domestic as well as commercial buildings. EPS is also well proven in civil engineering applications where its inherent strength means it can support structures such as roadways and railways with complete ease.
Can I put Styrofoam in concrete?
Lightweight concrete, also known as EPScrete (expanded polystyrene concrete), is a material widely used in the building of environmentally “green” homes. The substance is often made using small Styrofoam balls as a lightweight aggregate instead of the crushed stone that is used in regular concrete.
Can I add Styrofoam to concrete?
Mix a batch of concrete using 1 part water, 2 parts cement and 3 parts Styrofoam granules. Mix the cement with the Styrofoam first and then add in the water at the end. You should have a damp mixture that isn’t too wet to form into shapes. Let the cement sit for one to two days before using it in any construction.
What is the structure of polystyrene?
(C8H8)n
Polystyrene/Formula
How strong is polystyrene?
What are the properties of PS?

|---|---|
| Tensile Strength | 53 MPa (7700 PSI) *** |
| Flexural Strength | 83 MPa (12000 PSI) *** |
| Specific Gravity | 1.04 |

Is polystyrene water resistant?
Extruded polystyrene insulation (XPS) is manufactured using a process of extrusion. The closed cell structure of extruded polystyrene (XPS) prevents water penetration to the structure of the insulation board and provides long term strength and durability.
What are the uses of polystyrene?
Solid and film polystyrene,used in rigid foodservice containers,CD cases,appliance housings,envelope windows and many other products.
What is the purpose of polystyrene?
Polystyrene PS foam or expanded polystyrene as its more often referred to, is mainly used within the packaging industry, used as a high impact packaging solution to protect a large range of products from damage during transport or storage.
What can polystyrene be made into?
Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic aromatic hydrocarbon polymer made from the monomer styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight.
What is the definition of polystyrene?
Definition of polystyrene. : a polymer of styrene; especially : a rigid transparent thermoplastic that has good physical and electrical insulating properties and is used especially in molded products, foams, and sheet materials.
