Carbon content has a strong influence on room temperature strength and thus the specified minimum tensile properties of 304L are 34 MPa (5,000 psi) lower than for 304. However, nitrogen also has a strong influence on room temperature strength and a tiny addition of nitrogen produces 304L with the same tensile strength as 304.
Unlike traditional concrete structures, polymer concrete requires no coating or welding of PVC-protected seams. [4] It can also be used as a bonded wearing course for asphalt pavement, for higher durability and higher strength upon a concrete substrate, and in skate parks, as it is a very smooth surface.

Twenty eight days is a long wait to determine if desired strengths are going to be obtained, so three-day and seven-day strengths can be useful to predict the ultimate 28-day compressive strength of the concrete. A 25% strength gain between 7 and 28 days is often observed with 100% OPC (ordinary Portland cement) mixtures, and between 25% and 40 ...
Tensile strength is the most used method to evaluate filler materials. The tensile strength of the composite can be calculated using the equation σ c = σ p (1-aΦ b f +cΦ f d) [13] where σ c = tensile strength of composite σ p = tensile strength of polymer matrix Φ f = volume fraction of filler
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
A normal-size fiber for European shotcrete (1 mm diameter, 45 mm length—steel or plastic) will increase the concrete's tensile strength. Fiber reinforcement is most often used to supplement or partially replace primary rebar, and in some cases it can be designed to fully replace rebar. [41]
Also, with the higher carbon range in the hardened and lightly tempered condition, tensile strength of about 1,600 MPa (230 ksi) may be developed with lowered ductility. Martensitic stainless steel can be nondestructively tested using the magnetic particle inspection method, unlike austenitic stainless steel .
