FOREWORD This Indian Standard (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draft finalixed by the Cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in 1953 under the title 'Code of ...
Cast irons like steels are basically alloys of iron and carbon. Cast irons contain between 2 and 6.67 percent carbon. Since the high carbon content tends to make cast irons very brittle, most commercially manufactured types are in the range of 2.5 to 4.0 percent carbon.
Cement specifications clearly needed a way of prescribing the fineness of cement, and the sieve method was written into standards in the absence of any more useful measure, despite the fact that it provided little guidance as to the likely quality of the cement, particularly as the number of different grinding technologies multiplied.
Design for Maintainability: The Importance of Operations and Maintenance Considerations During the Design Phase of Construction Projects. Resource Page – 08-01-2018. This resource page presents a methodology that links operations and maintenance goals to the design process, and how it can be applied to any organization.
Highlights Almost 20% of CO 2 emissions by cement plant could be mitigated by shifting to dry process with calciner instead of wet process. Due to economic, technical and legal barriers, widespread cost-effective deployment of CCS is not foreseen before 2020. Utilizing industrial by-products resulted in the greatest contribution in emissions mitigation.

CO 2 emitted from calcination processes in kilns comprises 60% of all emissions from cement production. The chemical components of building materials, demolished inorganic building materials (DIBMs), and waste concrete powder (WCP) are similar to those of cement minerals.
The first attempt to get around this was to use separately-fired "drying floors" on which the final drying of the 25% moisture-content cake was sped up, at some considerable extra energy expenditure, and this became the normal "wet-process" for bottle kilns from around 1850.
The father of the dust collector was Wilhelm Beth from Lübeck. In 1921, he patented three filter designs that he had pioneered to remove dust from air. Uses. Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams, or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere.
