Portland Pozzolana Cement
Useful for general construction works and especially suitable for works in aggressive environmental conditions, employed for water retaining structures, marine works, mass concreting, such as dams, dykes, retaining walls, foundations, and sewage pipes. Portland Pozzolana cement utilizes two types of pozzolanas: a) Fly ash - Covered under IS 1489 (part I) b) Calcined clay -Covered under IS 1489 (part II) PPC with fly ash, as Pozzolana, is more popular in the country owing to the easy availability of quality fly ash from modern coal based thermal power plants. Portland Pozzolana cement is manufactured either by inter-grinding Portland cement, Clinker, gypsum and fly ash obtained from thermal power plants, or by intimately blending OPC and fly ash. The percentage of fly ash in PPC permitted by IS: 1489 varies from 15 per cent (minimum) to 35 percent (maximum). PPC accounts for nearly 47 per cent of the cement produced in the country PPC provides improved workability, has less segregation and bleeding, increased water-tightness and reduced tendency of lime to leach out It produces less heat of hydration and offers greater resistance to the attack of aggressive waters containing sulphates and chlorides. It improves the durability of structure, and also the strength of concrete over a period of time. It protects concrete against alkali-aggregate reaction. The fly ash in PPC helps to improve the impermeability of concrete by converting Ca(OH)2 into calcium silicate hydrate (C-S-H) gels and make concrete denser. . PPC is becoming popular in construction industry and its market share is progressively increasing. PPC can be used with advantage for masonry mortars and plastering. Indeed it can be used wherever OPC is usable under normal conditions. Although in the case PPC the development of strength at initial stages, say up to 7 days, is lower, PPC progressively improves and not only catches up with OPC in strength but also overtakes it during the life of the concrete. Hence durability is higher. As per the revised code IS : 456:2000, a minimum curing period of 10 days is prescribed for PPC and for OPC it is 7 days in dry and hot climates. For improved performance, concrete with PPC calls for sustained curing of at least 14 day
Ordinary Portland Cement 53 Grade
‘A high – strength OPC, used for high-rise buildings, bridges, flyovers, chimneys and prestressed concrete structures where high grade concrete (>- M30) is normally required.Advent of this grade of cement in the country owes to the improved technology at modern cement plants,which enabled production of high quality clinker.This grade was introduced in the country in 1987 by BIS and commercial production started from 1991.‘53’ grade cement is a high-strength OPC, which provides numerous advantages. wherever concrete for special high strength applications is required.It is available on regular basis in the market under different brand names.It accounts for approximately 20 per cent of the total production of cement in the country.
Ordinary Portland Cement 43 Grade
Ordinary Portland is most commonly used cement across the industry and we follow the best practice to ensure that the cement is delivered in sufficient quantity for the markets. Also referred to as grey cement or OPC, it is of much use in ordinary concrete construction. In the production of this type of cement Limestone, Al. Laterite / Iron Ore, Coal and Gypsum components are required. We produce the OPC 43 Grade
Our Product Quality
Quality consistency is an on going activity at Bhavya cements. Our priority is always to implement new technologies with in a time frame even at a huge investment and to be one of the best quality cement producing industry in India.Quality was given the prime importance even during the construction stage of the project itself. The layout planning, equipment sizing, technology absorption etc. were considered purely based on quality aspect of view. BCL has a separate Laboratory with quality equipment at plant for quality testing of our cement periodically. Bhavya Cements has got IS12269 certificate for 53Grade and IS8112 certificate for 43Grade from Bureau of Indian Standards.
