Polyester mortar : properties, energy absorption

الملخص EN

Due to its superiority and advantages, a type of polymer mortar based on polyester is proposed as a construction material.

A mix consists of polyester to sand of ratio 1 : 5 was found to be the optimum.

Samples were tested in compression at different ages to determine the compressive strength and the optimum hardening period.

Other essential mechanical and physical properties of the material were evaluated.

The stress-strain diagram of the material in compression was also established.

The diagram was used to evaluate the modulus of elasticity, toughness, resilience and ductility of the proposed material.

Along with the observed very high energy absorption capabilities of the material, ultimate strains, reaching 40%, were noticed.

The observed high resilience along with high tensile and flexural strengths of the material will reduce the cracking in the tension zone and hence, increase the material durability.

It was concluded that the proposed material is much superior to conventional concrete.

The presented paper contains the properties of the proposed material.
