Cement Manufacturing
(a) Processed sewage pellets (PSP) as rotary kiln fuel:
Having received approval from The Scottish Environment Protection Agency (SEPA), Lafarge began its evaluation of processed sewage pellets (PSP) for use as a new waste-derived fuel at its cement plant. The results will be reported in April 2013. If the trials are successful, the addition of PSP shall take the coal replacement in the plant to 50%, which also includes tyres and recycled liquid fuels. Waste-derived fuels offer many benefits such as maintaining the environmental performance, reducing carbon footprint and managing high energy costs. Read more
(b) Use of alternative fuels in Indian cement industry:
With the rising fuel costs and the focus on reduction of carbon footprint, Indian cement plants are likely to use alternate fuels in greater variety and quantity in future. Read more.
(c) Cement mill heat balance:
Only about 5% of the power supplied to cement ball mill is used for size reduction. Rest is wasted in heat generation. Therefore heat balance on cement mill is important. Read more.
(d) Ball mill sizing:
This paper explains how to size a cement ball mill with the well-known Bond formula. Efficiency correction factors are applied with the Bond equation. The method is valid both for clinker grinding and for raw materials grinding. This method only gives a rough and initial idea for sizing a cement ball mill. Read more.
(e) Wind power for CEMEX plant:
The two turbines in
Victorville will produce an estimated 6,500 megawatt hours of electricity in an
average year -- enough to sustain 650 average homes, according to CEMEX. Read more.
(f) Giving back to the community:
As part of a larger global movement in honour of parent company Holcim
Ltd's centennial in 2012, the initiative encouraged all 3000 Holcim Canada employees
to give back to the communities where they live and work. Read more.
(g) Nano-enabled cement:
Though the application of nanotechnology in cement industry is an emerging area, the trends in patent data indicate that commercial adaptation of this technology has already been started and in the near future nano-enabled cement is poised to occupy the cement industry in a big way. Read more.
(a) Common man's method to check the health of concrete:
When a builder claims that his buildings are the strongest and most durable he invariably means that the building’s concrete, apart from all other material used, is of the best quality. How do we verify these claims? The only thing that a layman can do is visual inspection through which one can determine that a structure is devoid of any irregularities or visible fractures. The core tests are mainly suitable for determining the strength of major projects like dams and bridges or on big constructions. Being a semi-destructive testing method, this test may not be the best option for smaller buildings and constructions. The non-destructive testing is helpful in determining the strength of a building without harming the structure. Read more.
(b) High-rise construction:
The future of high-rise construction will be high-strength, more durable, and more sustainable concrete. Read More.
(c) Giant concrete beams:
The massive precast girders — each measuring about 27 metres (90 feet) in length. Have a look.
(d) Engineers' mindset is important:
(e) Pervious concrete:
Building walkways, access roads and parking lots with pervious concrete is among the best ways to recharge groundwater and manage storm water runoff. Read more.
(f) Top ten construction projects of 2012:
It has been a year for construction industry. Read more.

(a) Acti-Gel® 208
Produced by Active Minerals International, LLC, is a highly purified hydrous magnesium aluminum-silicate made from a patented process that creates pure, uniformly sized rod-shaped mineral particles. It is a high-performance, thixotropic anti-settling agent and rheology modifier, used in wide variety of water based industrial applications, regardless of pH. In concrete products, it is used as mineral viscosity modifying agent (VMA), in pumpable and sprayable concrete products, such as SCC mixes, mine seals, geo-polymer concrete, precast concrete, cellular concrete, hollow-core slab, pavers, ground consolidation, aggregate piers, caissons, shotcrete, mortar, plaster grout.
