Heidelberger Cement Buy
The stock analysts at SGZ-Bank recommend this week that the share of the building material supplier Heidelberg Cement (WKN 604 700) for sale. Despite a still poor German construction industry - is the domestic sales increased only slightly accordingly - that society can increase its sales in the first half by 10% to 3.64 billion marks for the full year and expect growth of about 6 %.
Thus, I continue the trend of recent years had made in which Heidelberg Cement, despite unfavorable conditions a steady revenue and earnings growth. These relatively positive development was due primarily to the strong regional diversification of the business. While were built because of the critical situation in East Germany, especially in the building materials sector like cement, where significant over-capacity site consolidations and restructuring of the sales were necessary to the business in Western Europe and North America was a very good year. Accordingly, the management put on a further expansion in promising markets.
In addition to building a new plant in the U.S., which would cost as now the biggest single investment about 250 million dollars, would complement involvement in future growth markets of Southeast Asia as well as Romania and Poland's business portfolio. As part of the general market recovery, have the shares of Heidelberger cement AG removed from their annual lows and back to a level above the rates of the year. The support zone formed during the downturn by 140 DM is now a resistance that must first be overcome. The stock specialists SGZ-Bank indicate that the share ownership with a P / E of 13.5 based on the earnings estimates for 1999, a moderate rating, which make them interesting as a long-term investment. In addition, it was likely that the construction sector to recover in the medium term and also contribute to the positive momentum will change in government.

Report of 5 Holcim Concrete Forum on concrete innovations
"
(11/28/2010) For the 5th Holcim Germany once invited to a concrete forum that was hosted this time in Hamburg Curio-Haus. The invitation under the motto "concrete innovations" were more than 280 professionals from the construction industry followed. As a leading presenter, as in former years, the journalist Peter von Sassen from the NDR with the event. In his opening remarks, Leo Mittelholzer, CEO of Holcim (Germany) AG, concrete that had not yet reached its potential and innovation are of great importance to the long term in the market.
With Prof. Dr.-Ing. Harald Budelmann from the Technical University of Braunschweig, the first officer went to the "concrete technology innovation potential for building" one. The most important advances were achieved in the development and improvement of concrete raw materials and the manufacture and finishing of concrete. The "concrete modular" he demonstrated the innovative strength of concrete at various examples from practice.
Then presented Dipl.-Ing. Hans Joachim Christian, Dipl.-Ing. Lindemar Hänisch of the DESY Hamburg "Outstanding Concrete Structures for research in the DESY" before. Were brought closer to the audience the two projects PETRA III and the European project to build the X-ray laser XFEL, which allows molecular and atomic processes, as it filmed and snapshots of the atomic details can be manufactured in materials.
A fascinating insight into the topic "Nanotechnologically optimized ultra-high performance concrete with multiple characteristics" was the event participants, Prof. Dr.-Ing. habil. Michael Schmidt of the University of Kassel. "We are in the century of high-performance concrete," said Schmidt, and made the differences of building materials with their individual structures significantly. Thanks to the insights gained from the nanotechnology could significantly improve ordinary portland cement and concrete.
In the subsequent presentation, Prof. Dr.-Ing. Ludger Lohaus from the Leibniz University Hannover, concrete technical approaches and development strategies for robust concretes before. An optimal use of water ", where each drop of water which is supplied to the concrete is also used, is it the key to a high robustness and the avoidance of defects in the concrete.
About the Innovation Award Ceremony "energy storage concrete" informed Dr. Frank Huber of the cement + concrete trade and promotional gifts. m.b.H from Austria. The focus of the award-winning construction projects was on the reduction of energy consumption for air conditioning of buildings by the thermal activation. After his presentation of the four winners of the Auditorium, he invited her to visit the places to visit.
The event was rounded off with the post by Roland Bos (advertising agency Scholz & Friends) on sustainable ideas for the future. The advertising man looked at the concrete building material from the perspective of marketing and illustrated with several examples of how products can be targeted by advertising communication successfully set the scene. Building with concrete is innovative, communicating with concrete stand still in its infancy.
In a final plenary discussion, the participants exchanged especially over the image of concrete. The framework of the 5th Holcim Concrete Forum took Dr. Mathias Hoeppner, director of Technical Marketing, to present together with his team, the interested participants with the pre-cast cement Holcim Pur 5 premium and the related brochure, the latest product development from Holcim (Germany) AG.

Artfully: Designing with colored concrete
The color concrete by pigments is not a new procedure. But thanks to technological progress, concrete color concrete delight of architects, planners and builders today particularly popular. With colored concrete made it a far more lasting color results than with a subsequent painting and much more intense colors than by colored aggregates alone. This corresponds to the color of concrete ideas, but experience and know-how are essential in the production of concrete, because it applies different factors to control properly.

Cement and color pigment choice
Even if the concrete is colored with pigments, the brightness of the cement used plays a large role because it determines the basic color of the concrete. With bright cements, as a rule with portland cement or blast furnace, so CEM II and CEM III, there are, in principle, be made deeper, purer colors. These cements are mainly in bright colors such as pastels and of course recommended for very white. Dark red, ocher, brown and black on the other hand can also be set well with darker cements. are pigments for coloring concrete is targeted in various forms such as powders, granules, beads or liquid paint. Each has its advantages in certain applications. The mostly inorganic pigments are added to the formulation of concrete production and color the cement paste which surrounds the mineral aggregates and connects.

With iron oxide pigments, for example, concrete can be colored red, yellow, black and brown.
With the mineral pigment ultramarine and cobalt blue are achieved various degrees of blue.
Chromium oxide and chromium hydroxide green result.
Titanium oxide pigment colors the white concrete.
Even with relatively low pigment added a great color effect is achieved. Depending on the nature of the pigment and the desired color result dose the employees of the concrete manufacturer is usually between 2 and 6% of the share of cement color pigments into the concrete. The color intensity initially increases linearly with the amount of pigment, stagnating at a certain percentage, the color saturation level - the addition of other pigments will show hardly any effect. Since the pigments represent a not underestimate the cost, knowledge about the optimal dosage avoids unnecessary expenditure. be expected, however, must be below the saturation level more with fluctuations in the shade. The timing of the addition of the pigment has to be right:
Powder and granules are about before,
Liquid color by the addition of water in the mixer.

For colored concrete is the same as for any concrete vision: the establishment of a stable, well-processed formulation is an important basis for making desired end result. But it is not enough. At each step, from planning to installation and after-treatment should the project partners to vote in detail in a concrete team.

Yes to the cement kiln
With a clear majority of the council has ensured that the native of the 1960 furnace is in the cement plant modernization Schelklingen after going on a continuous operation. 18 city councils of the CDU, SPD and the liberal voters voted in favor, six boards of Pro Schelklingen it. Stefan Auer, Chairman of Pro Schelklingen criticized the project as of Heidelberg Cement again. There were indications that the oven will already operating since January without authorization and compliance with the limits. Moreover, the issue of noise pollution has not been clarified sufficiently. Lothar Knieß (CDU) called for continuous operation. That technology was upgraded, be good for Schelklingen.
The furnace was never operated without a permit, said the head of the cement plant, Hans-Georg Kraut, after deciding against our newspaper. The currently applicable limit values were always observed - but only for a time, with temporary funding. Now the technology is permanently installed, so did the local council must give its approval.
The decision on the further development freeze for the area of the cement plant, the municipal council to 15 December was postponed because certain documents were missing. With the preservation order, the city prevent the construction of waste incineration plant, in the so-called alternative fuels (RDF) should be fired. Jürgen Glöckner (CDU) asked whether a vote would be to extend the barrier later this year. Mayor Michael Knapp said this. ben
