Hello, I want to know is it possible that the compressive strength of concrete increase by reducing tensile strength? if yes, how we can explanation and justification this issue?
Hi Ehsan,
I don't think so. Tensile strength of concrete directly related to Compressive strength and it's basically 8-10% of comprehensive Strength. With the increment of comprehensive Strength, it is obvious to increase tensile strength.
Hi Ehsan,
Concrete is basically weak is tension you must be know that. Its' for compression force. Further, if you want to increase the compressive bearing capacity, then you can use fly ash, slag with cementation matetials as an admixture. The tension strength is increased simultaneously with increase in compression Strength as i know.
Concrete tensile strength is mainly a function of its compressive strength. Increasing the compressive strength increases the tensile strength. Ft ≈ 0.1 Fc
The mechanical and elastic properties depend on several aspects. However, mineral additions that promote porosity mitigation, for example, simultaneously favor compression and traction (~0.1xFc).
Typical concrete materials are designed for withstanding compressive strength. Different mineral and admixtures can be used to modify its compressive strength and tensile strength simultaneously affected as well. It is possible to enhance the tensile strength using reinforcing such as fiber however the opposite is most of the case not required.
I think that not possible since there is a strong relationship between the compressive strength and the tensile strength of concrete.
The failure of concrete, whether in investigating compressive strength or tensile strength, occurs due to the inability of concrete to resist tensile stress.
Mostly strength changes (increase or decrease) due to admixture content. However, it's not possible to draw a solid line between compressive and tensile strength as these two parameters depend on the same properties. Hence, the inclusion of these properties would alter strength as a whole.
