I want to increase tensile strength of concrete.as a civil engineer we all desired a safe and economic structures that's why we use reinforcement so that it can take tension but now a days steel is becoming costly material as huge amount of steel is needed in one structure so I thought if I increase tensile strength of concrete then less steel will be used.
I searched ITZ in internet and I found that CH are responsible for less bonding in ITZ zone so how can i replace CH with CSH gel in the ITZ zone? or any other solution regarding this problem
Mr. Paul,
Your question is very interesting that how to increase tensile strength of concrete..today, many research is going on all over world on this topic..From the literature it is observed the tensile properties of concrete can be improved using various materials such as nano particles, nano tubes, nano fibers and waste steel wires. The utilization of waste steel wires is also an eco-friendly phenomenon to improve the mechanical properties of concrete. ok all the best in your research..
Tensile strength of concrete can be improved by adding steel and fiber. this will increase the cost also, so as a civil engineer we have to find optimal point for tensile strength against the cost. Despite the increase in tensile strength, but it remains less than compressive strength of the concrete. Remember that we can increase the compressive strength, since the tensile strength has relation with compressive strength so this will increase the tensile strength. Also, the use of propylene fibers and microsilica fume (gel) increases the tensile strength and compressive strength of concrete.

Concrete resistance to tensile strength is very poor compare to the huge resistance of concrete to compression. Reinforcing steel, wire, fiber a generally used to enhance the tensile resistance of concrete. Other materials such china bamboos, and some waste steel wires are cost effective materials that can be utilized to improve the tensile resistance of concrete.
Higher adhesion of the aggregate to the cement matrix should be ensured by the use of dust-free rock aggregates. Increasing the density of the material, deaerating and compacting the concrete mix.
Tensile strength of concrete can be improved by adding steel and fiber, fiberglass. Nano-materials in cementitious matrix can increase the tensile strength too.
It is not all about strength, strength play an important rule, but additional properties are needed to create safely, durable, sustainable environment.
The word "economic" depend on several parameters, not just the amount of materials used in the concrete mix, or size of members.
By reducing the cement weight, we can increase tensile strength up to 66%. By using nano particles, we can further increases tensile strength up to 45%. Waste steel wires are also effective; their strength is also increased.
What measures can be taken to improve the tensile strength of concrete?

Tensile strength of concrete can be increased by increasing its compressive strength as tensile strength is proportional to square root of compressive strength. Further you can add steel or glass fibers to the concrete mix. This will have the most beneficial effect on tensile strength.
