What are the mechanical properties of mortar?
Mechanical properties such as compressive strength, water absorption, and flexural strength were measured. The results showed that this type of aggregate is not only economical but also has good effects on mortar mechanical properties.
What is rubberized concrete?
Rubberized concrete is a type of concrete that is mixed with rubber. The rubber reduced the density and compressive strength of the concrete while increased the flexural strength, water absorption and damping ratio. The used of rubber in concrete beyond 20% is not recommended due to decreasing in compressive strength.
Is silicone rubber thermoplastic or thermoset?
The liquid silicone rubber (LSR) part (right) is a popular thermoset material choice.

What is polymer concrete composite?
Polymer concrete is a composite material in which the aggregate is bound together in a matrix with a polymer binder. The composites do not contain a hydrated cement phase, although portland cement can be used as an aggregate or filler.
What is the tensile strength of silicone rubber?
(Review the links to each selection guide for more details.) HCR – High Consistency Silicone Rubber – typical tensile strength range from 4.0 to 12.5 MPa. FSR – Fluorosilicone Rubber – typical tensile strength from 8.7 to 12.1 MPa. LSR – Liquid Silicone Rubber – typical tensile strength range from 3.6 to 11.0 MPa.
What are the mechanical properties of rubber?
Mechanical Properties of Rubber Nanocomposites Containing Carbon Nanofillers 12.3.1. Elastic Modulus. An elastic modulus (Young’s modulus) that characterizes the resistance of rubber composites to being deformed elastically (i.e., nonpermanently) is defined as the slope of its stress-strain curve 12.3.2. Tensile Strength. 12.3.3. Tear Strength. 12.3.4. Dynamic Mechanical Properties. 12.3.5. Other Mechanical Properties.
What is silicone rubber foam material?
Silicone foam products are manufactured from platinum cured, liquid silicone rubber . The raw compound is expanded and dispensed on a continuous casting line, then heat cured. The expansion process is controlled to create a range of products having different densities, softness/firmness and cell structures.
