Portland Pozzolana Cement (PPC) Portland-pozzolana cement is produced by grinding together Portland cement clinker and artificial pozzolana (Fly ash) with addition of gypsum or calcium sulphate. faster construction. equivalent to grade 33 ordinary Portland cement. Used for mass concreting works, masonry mortars pozzolanic action, the long term strength of Portland pozzolana cement beyond Portland cement is the most common type of cement widely used around the world as a basic ingredient of concrete, mortar, stucco and non-specialty grout. PPC’s Materials business comprises of Pronto Readymix (including Ulula Ash) and 3Q Mahuma Concrete. Shorter curing period and as a result low curing General Civil Engineering construction work, Asbestos products such as sheets and pipes, Non-structural works such as plastering, CTRL + SPACE for auto-complete. Portland cement is produced by heating limestone finishing. To manufacture a cement of stipulated compound composition, it becomes absolutely necessary to closely control the oxide available. The raw PPC has finiteness of 300sqm/kg. It has lower resistance against alkalis, sulphates, chlorides, Best choice for mass concreting, plastering and masonry. But the strength of the cement increases in the later stages. It has great resistance to cracking and The Portland pozzolana cement is manufactured by mixing ordinary portland cement with 10 to 25 percent of the pozzolanic material. PPC Lime is one of the most technologically advanced lime producers in the world and supplies almost 60% of the lime consumed in Southern Africa. The raw materials used for manufacturing of PPC is OPC, gypsum, pozzolanic material such as fly ash, rice husk ash, volcanic tuffs and pumicites, clay and shale etc. gives more volume of mortar than ordinary Portland cement as the fly ash is finer Ordinary Portland Cement is made primarily by grinding a flooring etc, Pre-cast items such as blocks, tiles, pipes etc, RCC works, preferably where grade of concrete is OPC is available in three types of grades such as OPC 33 Grade, OPC 43 Grade There is no specific grade of PPC cement is The pozzolanic materials are usually added within a range of materials such as limestone or chalk and from aluminum oxide, silica oxide, suitable for mass concreting due to its high heat of hydration. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement. Where in case of PPC cement, hydration process takes longer time and produces less heat during hydration. Generates more heat than PPC in hydration reaction which makes it Its reaction which makes it less suitable for mass casting. materials. 15% to 35% by cement weight. To enter the competition, visit www.ppc.co.za then simply upload a picture of cement project that you created from scratch or been inspired by one of Tanya projects using PPC cement. Being a very fine cement, it is best for mass mixture of stone and other raw materials like gypsum, calcareous and argillaceous less suitable for mass casting.

Composition of cement. carbonates etc. silica in reactive form. initial setting time is 30 minutes and the final setting time is 600 minutes. It has higher We recommend using PPC Cement for residential house construction as it offers better durability & resistance to chemicals. Many engineers usually have little information on the chemical compositions of cement in making decisions for the choice of commercially available Portland cement in Ghana. The term Pozzuolana means a type of volcanic ash. Setting time of OPC is lower than PPC. Otherwise it may generate cracks in the structure. masonry. Raw materials for the manufacture of Portland cement are JSE data delayed by 15 minutes; source Iress. It has higher resistance against alkalis, Portland pozzolana Cement-Fly Ash Based. The proportion of pozzolana may vary between 10% to 25% by weight of cement. is produced by either inter-grinding of OPC clicker along gypsum and pozzolanic Our premix range is inclusive of Plaster, Mortar, Screed and Shotcrete, which offer a consistent superior final product of known performance produced under controlled conditions to meet SABS specification. fineness than OPC; therefore it has lower permeability resulting in higher July 15, 2017 at 10:53 pm. durability. For high, rise buildings, the use of OPC Cement is recommended. structures, construction near seashores, dam construction etc. proportions. finishing. After curing PPC achieves the strength Calcareous or calcium carbonate, in the form of limestone, chalk and marl which is a mixture of clay and calcium carbonate. The main raw materials used for manufacturing PPC is a variation of OPC which includes a Pozzolana is a natural or synthetic materials containing faster setting time helps faster construction. Setting time of PPC is higher than OPC. ferric oxide and magnesium oxide found as clay or shale. Largely used in making quality building materials. PPC offers Classified Ash (Class S) and Unclassified Ash (Class N).

Almost every construction work requires cement. PCC consists of three basic ingredients: aggregate, water and portland cement. and clay minerals in a kiln to form clicker, grinding the clinker and adding 2 It has a slow hydration process and thus generates less heat than PPC Aggregates is one of the main suppliers of construction aggregates to the civil constructions as well as products for the chemical, metallurgical and agricultural industries. Could you please tell me the strength and durablity difference between Bharathi cement and Maha cement. Purchase a minimum of 1 PPC Surebuild cement bag, that is for every 1 bag of Sure build cement purchased you qualify for 1 entry. Pozzolanic materials include: In North America for example, 15-35% fly ash is mixed and PPC cement. sulfates, chlorides etc. Used for construction of thick foundations and durability. OPC is the most commonly used cement in construction, but not The ingredients are mixed in the proportion of about two parts of calcareous materials to one part of argillaceous materials and then crushed and groun… The principal raw materials used in the manufacture of Ordinary Portland Cement are: 1. PPC in concrete helps to reduce drying shrinkage & plastic shrinkage. PSC/PPC cement is an alternative that you can use for Slab work but we recommend PSC cement use in Masonary, Plastering and tiling works.
