What is Polymer concrete?
It is also known as resin concrete because synthetic resins are used instead of cement in its manufacturing.
Density of cement concrete- Density of normal concrete is in the order of about 2400 kg per cubic metre. The density of light-weight concrete will be less than 1900 kg per cubic metre.
- To call the concrete, as high density concrete, it must have unit weight ranging from about 3360 kg per cubic metre to 3840 kg per cubic metre, which is about 50% higher than the unit weight of conventional concrete. They can, however be produced with the densities upto 5280 kg per cubic metre using iron as both fine and coarse aggregate.
- The high density concrete is used in the construction of radiation shields.
Density of polymer concrete
- Normally, the density of polymer concrete is not more than 2260 kg per cubic metre, when you use normal aggregates like granite stone chips and river sand as you do in standard cement concrete.
- When you use aggregates obtained from iron ore or iron rod pieces, you can make high density polymer concrete upto 5140 kg per cubic metre.

The name of the plastic polymer from which plastics bags are made is?
Plastic bags are typically manufactured from high density polypropylene (HDPE - plastic number 2) or low density polypropylene.
What is monomer density of a polymer?
Monomer density of a polymer refers to the concentration of monomer units within the polymer structure, typically expressed in terms of moles per unit volume. It gives insight into how densely packed the repeating units are within the polymer, which can influence the material's mechanical and thermal properties. Higher monomer density often correlates with increased rigidity and strength, while lower density may result in more flexible and elastic characteristics. Understanding monomer density is crucial in polymer chemistry for tailoring materials for specific applications.
What are the properties for HDPE?
High-density polyethylene (HDPE) is a thermoplastic polymer known for its high strength-to-density ratio, chemical resistance, and ease of processing. It is commonly used in a wide range of applications including bottles, pipes, and packaging due to its durability and recyclability. HDPE has a melting point range of 120-180°C and a density of around 0.95 g/cm³.
What is crosslink density?
Crosslink density refers to the number of chemical bonds connecting polymer chains in a network structure. A higher crosslink density results in a more compact and rigid polymer structure, leading to increased mechanical strength and resistance to solvents. This property is important in determining the physical and mechanical properties of a polymer material.
How dense is concrete?
Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.
What is the meaning of the acronym HDPE?
High Density PolyEthylene. A polymer/plastic.
The name of the plastic polymer from which plastics bags are made is?
Plastic bags are typically manufactured from high density polypropylene (HDPE - plastic number 2) or low density polypropylene.
What is the Density of concrete?
Density of normal concrete is in the order of about 2400 kg. per cubic metre. The densityof light-weight concrete will be less than about density 1900 kg per cubic metre.The high density concrete have unit weight ranging from about 3360 kg percubic metre to 3840 kg per cubic metre.
What is concrete types?
High density concreteSulphur infiltrated concreteVacuum concreteHeavy weight concreteLight weight concreteNo fines concrete
How is density influenced by crystallinity?
higher crystallinity in a polymer = lower density
Is concrete a polymer?
Polymer concrete is a composite material which results from polymerization of a monomer/aggregate mixture. The resulting polymer binds the aggregate making the concrete stronger than ordinary concrete using just standard aggregate.
Which has greater density wet or dry concrete?
Dry concrete has a greater density than wet concrete because the water content in wet concrete decreases its overall density. When the water in wet concrete evaporates during the curing process, the concrete becomes denser.
What is the density of M-30 grade concrete?
Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m
What fraction of a piece of concrete will be submerged?
The fraction of a piece of concrete submerged in water depends on its density compared to the density of the water. If the density of the concrete is greater than the density of water, the fraction submerged will be less than 1. If the density of the concrete is less than the density of water, the entire piece of concrete will be submerged.
How to make ultra high performance concrete?
silica fume and quartz powder is added to make the concrete more denser. fine aggregates fill the voids between coarse aggegates, cement fill the voids between fine aggregate, silica fume fills the voids between cement and quartz powder fills the voids in between silica fumes
What is the density of the cement concrete grout?
The density of concrete can vary from 2,300 to 3,400 kg/m3.
