Portland Slag Cement, commonly known as PSC, is blended cement. If the cavity is a bit more deeper than you may need to use a stronger material like resin- modified GIC or a composite.

Both are ecofriendly materials but Pozzolana Cement uses natural and industrial waste thus reducing the environmental pollution. The Man Behind CivilJungle. Difference Between OPC Cement and PPC Cement. Its initial setting time is 30 minutes and the final setting time is 600 minutes. Portland Pozzolana Cement (PPC) is a variation of OPC which includes a mixture of a pozzuolanic material which can increase the strength of the concrete and reduce the amount of OPC used. So, the main components are OPC clinker, gypsum, and pozzolanic materials (15~35%), which include calcined clay, volcanic ash, fly ash, or silica fumes. PPC Pozzolana materials are added to the cement in the ratio of 15% to 35% by weight. This name ‘Portland’ was given by the British cement manufacturer Joseph Aspdin at 1824 because of its strong resemblance to Portland Stone, a type of white-grey limestone found at this isle of Portland, Dorset at England. For example RCC casting of buildings, mass concreting for bridges and even plastering and other non-structural works. I am a Degree Holder in Civil Engineering. Its initial setting time is 30 minutes and final setting time is 280 minutes. Setting Time: Setting time of PPC us higher than OPC. So, it can be used for mass concreting. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing. It is also used for most concrete masonry units and for all uses where the concrete isn’t subject to special sulfate hazard or where the heat generated by this hydration of cement isn’t objectionable. Definition: A mixture of limestone and other raw materials like argillaceous, calcareous, gypsum is prepared and then grinded to prepare OPC. It can thus be regarded as a binder, glue, or adhesive, which in its hardened state binds. Durability: More durable in aggressive weather. Thereby PPC is prone to educe shrinkage & less cracks ), better workability, and finishing. The concrete with OPC contains less workability whereas the concrete with PPC … Get Traffic & Exposure. Setting Time: Lower than PPC. As per the … PPC is available in one grade and its strength is similar to that of OPC 33 Grade after curing. {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What Is Cement? House Construction Cost Calculator Excel Sheet For Ground Floor(G.F.), G.F.+1, G.F.+2, G.F.+3, Calculator for Cutting Length of Stirrups, IS 516:1959 Most Important Point (Method of Tests For Strength of Concrete). Difference Between Plinth Level, Sill Level, and Lintel Level. Heat of hydration: Generates more heat than PPC in hydration reaction which makes it less suitable for mass casting. Strength: PPC has a higher strength than OPC over a longer period of time. CEM II is the Portland Composite Cement (PCC) where SCM or pozzolana is added by replacing the clinker. 2.3 Production of multi-component cements enables not only fuel energy savings (by 30-40%) but also increased volumes of concrete production. Fineness: OPC has finiteness of 225 sq.m/kg. The stability of concrete with OPC is less as compared to PPC whereas stability of concrete with PPC is greater than OPC. PPC and OPC Cement difference: PPC is a pozzolona portland cement whereas OPC is an ordinary portland cement. ","acceptedAnswer":{"@type":"Answer","text":"Evidence of the use of cement is believed to have been found in the hidden civilization of Mohenjodaro dating back 5000 years.\n\nThe ancient Greeks used some form of mortar, but it remained for the Romans to develop and use cement. Workability of concrete means how smoothly it can flow on the surface. Portland Cement - Portland cement is a basic ingredient of concrete, mortar and most non-specialty grout. Application: It is suitable for all types of construction work. Specification This cement complies with the 32,5 R strength class of SANS 50197-1 for common cements and is identified as: • Portland Composite Cement CEM II/A 32,5 R • Portland Composite Cement CEM II/B 32,5 R Where “CEM II” denotes Portland Composite Cement, “A” denotes an extender content between … Whereas the raw materials used to manufacture PPC are OPC cement clinkers 75 to 76 % and gypsum 3 to 5% and pozzolanic material 10 to 25% which can be fly ash, rice husk Ash, volcanic tuff, Pumicites, clay and shale all these materials are mixed and grinded to obtain the Portland pozzolana cement.. Grades. PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) PPC is a variation of OPC which includes a mixture of pozzolanic material which is known to increase the strength of concrete. Composite masonry is the one that is constructed out of two or more types of building units or of different types of building materials..
