aanilachyutha@gmail.com, b*thanujagutthi@gmail.com Keywords: Structural integrity, Material quality, Material testing, Safety, Durability Abstract: A construction building's structural integrity, material quality, workmanship, and conformity to design specifications were all assessed qualitatively.
A Almusaed[10] noticed that, it aims to objectively analyze materials' environmental impact and suitability for local construction needs.
To do this, water is sprayed over the concrete's surface. 2.2Test Methods based on materials used: Tests on cement: Soundness: One of the most important quality control tests for determining the stability and durability of cement is the soundness test.

This paper describes the materials and the methods used to make a tensile test of composite materail.
The tensile specimens were cut in three angles 0º, 90º and 45º because it’s orthotropic materials.
This standard is usually employed for the determination of tensile properties of reinforced materials.
