Topic: Trends and Growth in Cement and Concrete Technology Cement production has experienced a wonderful development since its inception some 2000 years ago to this present day. While the use of cement in concrete has a very long history, the industrial manufacturing of cements began right in the middle of 19thcentury, at first with chute kilns. These at a later time was replaced by rotary kilns as a standard equipment globally. Development While cement production has conventionally been engrossed on Ordinary Portland Cement (OPC) composite and gustboiler slag cements have been industrialized and part of a central part of the cement type portfolio of producers. At the same time Portland pozzolanic cements and Portland limestone have gained prominence, especially in areas where fly-ash or slag are not available. In the global situation of CO2 constraints and cost reduction, cement companiesattempt to lower the clinker content in their cements. There are limits which are given by cement performance, so that the cement product quality of the overall concreted may not be weakened. The decreasing of this clinker levels in cement products are mainly taken into considerationin as much as the internationalaccessibility of pozzolanic materials of industrial origin and latent hydraulic is surely limited, a special focus is on cements products that has a high level of limestone content.This is essentially an extension of the present cement norms as they have been developed globally and provide certain opportunities for the future. The Requirements for new technologies All cement product that is manufactured have to satisfy the basic requirements onits strength development, durability, early strength development, cost, workability and environment. Depending on the composition of the cement product, these standards can be satisfiedin different degrees. Therefore it now lies in Cement Company or producers of these cements to optimize the differences in the types of cement products in regard to these categories. The buy will have the choice to choose the suitabletype of cement for the committed construction. For new cements products to be developed in the future, their durability capacity is one of the crucial requirements. The enquiry aboutthe conflict against the penetration of chloride, carbonation resistance, only to give a few examples, which should be adhered to.
Future cements There are different cement product in existence. Celitement, as an example, is founded on calcium silicate hybrid phases. This Production is predicted by hydro-thermal mixture and by the reactive milling of lime in a silicon constituent. The Ca/Si ratio is lower when compared toOPC clinker, subsequently CO2 emissions and energy requests might also be lower. However, it is presently too early to state any valuation about the future potential of cements with respect to the production cost, strength or the practical potential for pertinent substitution of recent cements.Latest development on cements will surely be taken into account of a proven and welltried elements and will comprise of a lower clinker then it is currently.
