|What is the difference between tricalcium and dicalcium silicate?|
|Shweta said: (Aug 24, 2013)|
|It might be the proportion of calcium in the compound.|
|Nanaso said: (Sep 27, 2013)|
|Why ultimate strength to cement of di-calcium silicate?|
|Amol said: (Oct 14, 2013)|
|Tri calcium cement contributes in initial strength of concrete whereas di calcium silicate contributes in strength after 7 days.|
|Prajith said: (Dec 25, 2013)|
|The quality of cement is good, if it has more of Tricalcium silicate.|
|Mankatha Durai said: (Feb 4, 2014)|
|What is the purpose of tricalcium cement?|
|Shalu said: (Mar 28, 2014)|
|When water is added to cement, each of the compounds undergoes hydration and contributes to the final concrete product. Only the calcium silicates contribute to strength. Tricalcium silicate is responsible for most of the early strength (first 7 days). Dicalcium silicate, which reacts more slowly, contributes only to the strength at later times. Once set, concrete continues to harden (cure) and become stronger for a long period of time, often up to several years. So Ca2SiO4 gives ultimate strength.|

|Then what about tricalcium aluminate and tetracalcium aluminoferrite?|
|Vijay.M said: (May 13, 2014)|
|Basically Silica is an strength parameter and alumina is an setting parameter. If we need our structure to attain quick setting we need to increase the quantity of alumina (tricalcium aluminate and tetracalcium aluminoferrite). Vise versa for silica.|

|What is the purpose of di-calcium silicate?|
|Amardeep Kumar said: (Apr 21, 2015)|
|Tricalcium silicate and dicalcium silicate most to the eventual strength.|
|Amjad said: (Apr 21, 2015)|
|Now let and see:
Portland cement is made up of four main compounds: Tricalcium silicate (3CaO.SiO2), dicalcium silicate (2CaO.SiO2), tricalcium aluminate (3CaO.Al2O3), and a tetra-calcium aluminoferrite (4CaO.Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols.

|What is the difference between the function of tri calcium aluminate and tetra calcium alumino ferrite?|
|Naman said: (Jun 18, 2015)|
|Tri calcium aluminate gives plasticity and tri calcium alumino ferrite protect the corrosion.|
|Jaydeep said: (Jul 3, 2015)|
|What is plasticity?|
|Sabariii said: (Aug 22, 2015)|
|Plasticity is the property of regaining it's original position after removal of load in the structures.|
|Sandeep said: (Sep 7, 2015)|
|What is the ultimate strength?|
|Rakesh Roy said: (Sep 14, 2015)|
|Dicalcium = ca2, tricalcium = ca3.|
|Amaran Radha said: (Sep 24, 2015)|
|What should be the minimum final setting time of OPC 53 grade cement Chettinad brand?|
|Deepak said: (Oct 9, 2015)|
|Final setting time is 10 hour for OPC.|
|Ejaz Ahmad said: (Nov 25, 2015)|
|What is blended concrete can anyone tell me?|
|Anushree C P said: (Dec 8, 2015)|
|Blended cement is a mixing of with mineral admixtures or additives like fly ash, slag or silica fume.|
|Sh@Sha@Nk Tyag! said: (Dec 23, 2015)|
|c3s and c2s are major strength giving component in cement. For same amount of ater added (23%). c2a give more amount of c-s-h gel which bind cement molecule together.
c3a provide early setting characteristics while c2a react slowly but provide strength while hardening process.
|Bhuvnesh Malav said: (Jun 3, 2016)|
|Please, give theMajor differences of tri calcium silicate and Di-calcium silicate.|
|Danish Ahmad Rather said: (Aug 5, 2016)|
|Dicalcium silicate provides Ultimate strength i.e. strength after 7days and tricalcium silicate provides early strength ie, before 7 days.|
|Shashank Tyagi said: (Aug 9, 2016)|
|The answer is c2s, because same moles c3s and c2s, c2s will. Form more c-s-h gel resulting in long-term strength.|
|Mehul Modi said: (Sep 12, 2016)|
|The dicalcium silicate is provided initially low strength but with the time it increases the strength of cement.|
|Rahul Singh said: (Sep 20, 2016)|
|What is workability of concrete?|
|Prajapatijaydeepo said: (Sep 26, 2016)|
|It is characteristic of concrete to flowability.|
|Sahiya said: (Sep 29, 2016)|
|Whether Answer A is also correct?|
|Mujahid said: (Oct 9, 2016)|
|The C3s and C2s both will give strength to the cement.|
|Baloch said: (Oct 27, 2016)|
|Plasticity is opposite of elasticity,
Plasticity never regains its original shape after applied load as elasticity do.
Plasticity is a stage between liquid limit and plastic limit of the material.
|Harshit Agarwal said: (Dec 15, 2016)|
|Final strength of OPC is contributed by?|
|Amrit said: (Feb 21, 2017)|
|Tri- calcium silicate (C3S) has the property of hydrating rapidly and is responsible for providing not only early strength but also the ultimate strength.|
|Amit Bhate said: (Feb 23, 2017)|
|I think the Option A is a correct answer.|
|Jamil Manjotha said: (Apr 5, 2017)|
|According to me, option A is correct.|
|Haunted said: (Jul 9, 2017)|
|Option B is correct answer. Ultimate strength is due to di-calcium. Tri calcium provides initial setting. Then ultimate strength starts.|
|Mani Missile said: (Aug 6, 2017)|
|Tri-calcium silicate is response for early developing strength. So, why gives ultimate strength a di-calcium silicate.|
|Abhinandan Dakare said: (Sep 19, 2017)|
|C3S gives intial strength and C2S give Ultimate strength.|
|Hardik said: (Nov 10, 2017)|
|C3S is the answer for that question for me.|
|Gaurav Dhakate said: (Nov 26, 2017)|
|Di-calcium silicate gives progressive strength so how it can give ultimate strength?|
|Satish Rathod said: (Jan 5, 2018)|
|C3S hydrates rapidly generating high heat and develops as an early strength however C2S hydrates slowly and takes longer time to gain strength but strength for C3S and C2S will be same. Answer is C3S.|
|Shrikant Ambhore said: (Jan 10, 2018)|
|Tricalcium silicate would contribute more in gaining the early and ultimate strength of the concrete then that of dicalcium silicate. So C3S is the answer.|
|Salman said: (Jan 25, 2018)|
|Ultimate strength gain by C3S.|
|Ram said: (Aug 26, 2018)|
|Di-calsium silicate has give a ultimate strength provide.|
|Kala said: (Sep 24, 2018)|
|Add 25% of Di-calcium silicate in cement then it provide ultimate strength.|
|Monika said: (Sep 28, 2019)|
|Tricalcium aluminate responsible for initial setting time.
Tricalcium silicate responsible for initial strength.
Di calcium silicate responsible for ultimate strength.
Tetra calcium alumino ferrite responsible for the flash set.
|Ram said: (Dec 16, 2019)|
|I think C2S.|
|Bishnu said: (Jan 9, 2020)|
|Di- Calcium silicate responsible for the lateral strength of cement. C2S.
Tricalcium calcium silicate responsible Early strength of cement. C3S.
|Sneha said: (Oct 30, 2020)|
|As water is added to cement, it hydrates and forms tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite.
Tricalcium silicate forms immediately after hydration and responsible for early strength.
Dicalcium silicate contributes strength by around after 7 days and it is responsible for ultimate strength.
Tricalcium aluminate took months to impart strength after hydration and tetracalcium aluminoferrite took even years. Both are less significant in contributing to strength.
|Shiva said: (Jan 14, 2021)|
|What Are the Di-calcium silicate? Please explain it.|
