To understand the difference between tender documents and contract documents, first we have to understand what these documents contain.
Tender Documents:
A tender is an offer in writing to contractors to execute the some specified works or to supply specified materials within a fixed time frame and as per conditions of contract and agreement between the contractor and the owner or the department or the party.
The tender documents contains the bill of quantities (BOQ), specifications of the works to be carried out, time frame for the completion of the work, conditions of the contract and plans and drawings. These documents are provided to the contractor on the payment of certain fees. The contractor who quotes the lowest rates for the overall works are offer the contract to execute the work.
Contract Documents:
Contract documents are the agreement between the owner or the party or the department and the contractor to execute the works as specified in the tender documents as per conditions of contract on the rates quoted by the contractor.
The difference between Tender and Contract Documents:
The difference here to be noted is that tender documents are offered to as many contractors as possible to get the lowest quotes for the work specified, while the contract documents are signed only with the contractor with lowest tender or rates.
While the tender documents contains the conditions of contract and all the details for the specified work, there is not much difference between the two in terms of contents. But tender documents can not be submitted as Letter of Acceptance (LOA) as these are two different types of documents. While a tender document can not bind the contractor to do the work, a contract document binds the contractor to complete the work as per the agreement.
Simple Example to understand the difference between tender and contract documents:
When you are selected for a job in a company you are offered offer letter to join the company. But getting selected in a company does not mean that you join the same company, you may have other offer letters as well. But when you sign the letter of acceptance (LOA) for the job, you are bound to join the company. So, here offer letter from the company is a tender document and LOA is the contract document.

Generally, Ordinary Portland cement (OPC) is used in the factories, power plants and in large construction slabs.
Portland pozzolana cement (PPC) is used for the construction of houses, schools, and residential building slabs. PPC is cheaper than ordinary Portland cement. Thus to reduce the building making cost, PPC should be adopted.
Both the PPC and OPC cement is used in the construction of slabs.
Portland pozzolana cement is Better resistant to sulfate attacks. Thus PPC is used in underwater construction where water has some amount of sulfur quantity. Its setting time is higher than OPC.
