The Indian standard IS:456-2000 recommends the use of Portland pozzolana cement (blended cement) as well as mineral admixtures for concrete mixes provided that there are satisfactory data on their suitability, such as performance test on concrete containing them. In a bid to address incidences of building collapse in the country, the Federal Government on Friday inaugurated Pozzolana Cement Plant in Bokkos, Plateau. CONTACT: Brian Jeppsen | brian@hesspumice.com. The percentage of pozzolana available in this type of cement rages between %15 to %30 in accordance with the customers demand. The Minister of Science and Technology, Dr Ogbonnaya Onu, while inaugurating the plant, […] The Sectional Committee was of the view This type of cement is used for general applications as for massive structures due to having less hydration heat than the cement type 1 and 2; its most significant specification is the relatively higher chemical strength. We supply, trade and provide service for high quality Blended Pozzolana Cement. Generally two types of cement are available in market: Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). The new unit will create 400 jobs. The pozzolana cement industry is capital-intensive; therefore, it needs significant investment over the long term. Mixtures containing pozzolans of different fineness levels were tested for pozzolanic activity with lime. Application/Use: Oil-well cement is used for cementing work in the drilling of oil wells where they are subject to high temperatures and pressures. Special Portland Pozzolana Cement is used for dam constructing as well as other massive concrete- making projects requiring low hydration heat. The secret of Roman Cement was the mixing of lime with pozzolana, called harena fossicia or “pit sand” by Vitruvius. Due to the spherical shape concrete move more freely and more fineness of particles allows better filling of the pores. Pozzolanic oilwell cements are typically used to produce lightweight slurries. I. Addressing journalists, Ms Ayittey said Pozzolana had the potential to replace by 40 per cent the Portland cement used in the country and save the country $30 million per year on clinker imports. Portland Pozzolana Cement is highly popular in India and with many cement plants setting up jetties for transportation, initial costs would gradually decrease as well. Portland pozzolana cement(PPC) Sulphate resisting Portland cement; Oil well cement; White cement; Low heat Portland cement; Hydrophobic cement; Portland slag cement ; Ordinary Portland Cement(OPC) Three different grades of OPC were produced to overcome the different grades of concrete standards. The Indian standard IS:456-2000 recommends the use of Portland pozzolana cement (blended cement) as well as mineral admixtures for concrete mixes provided that there are satisfactory data on their suitability, such as performance test on concrete containing them. As per IS:1489 (Part 1), the Fly-ash constituent shall not be less than 15% and not more than 35% by mass of Portland Pozzolana Cement. Since the pozzolanic material reacts with calcium hydroxide liberated by the hydrating Portland cement and forms cementatious compounds, PPC makes the concrete more impermeable and denser. Ring in the new year with a Britannica Membership, https://www.britannica.com/technology/pozzolana. OPC is used for roads and infrastructure while PPC is used in real estate projects. PPC is an eco-friendly product as it is manufactured using fly-ash, a by-product from the thermal power plants. Inquire for Discount Inquire Before Buying.
