Directory of Highway for con structing concrete roads at two locations: One in Is tanbul and the other in Afyon. The protocol was signed by the Minister of Public Works Abdulkadir Akcan, General Director of Highways Dincer Yigit and the President of the TCMA Board Adnan Ignebekcili . TCMA will finance and help with the construction of the roads, which will be the firs t concrete roads ever built in Turkey. The Project is planned to be completed by the end ofNovember 2002.

A nationwide housing revival could provide a much-needed boost. Not too many in the Indian industry are really gung-ho about a speedy revival on the economic front. Cement prices are flat and demand is not showing any immediate signs of picking up and profits are skidding. Despite nursing a surplus capacity many of the industry majors are planning, not only to go ahead with their expansion plans but a lso firming up plans for setting up new greenfield ventmes. Investments are being made at a time when re turns on existing capi tal deployed in the indus try are far from adequate . Optimism taking more exposure is based on the hope of ongoing infrastructure projects picking up . Many firms are upbea t on the housing sector.

The most importan t elements of the project were the remova l of the old cooler and ins tallation of a 5000 tpd SF cross– bar cool er. The projec t a lso inc luded replacement of all heavy kiln sections, calciner and smoke chamber, downcomers from the top cyclone of ID fans and new control system. Performance measurements carried out recently show that the kiln system is operating a t a production level of more 5000 tpd at a hea t consumption of 821 kcal / kg clinker. This is prior to the upg rad ing project when hea t consumption averaged approx imately 1000 kcal / kg clinker at a production rate of 4200 tpd and a clinker temperature of 350 oc. Although the performance of the cooler installation is now impressive, (a clinker temperature of 77 "C and an ambient at 1526Nm3/kg clinker and cooler loss of 82 kcal / kg clinke r) , the mos t well– received feature of the cross-bar cooler is the simplicity of cooler operation. The precalciner sys tem is of the ILC type, which is suitable for rapid increase to full production. The cooling ai r fans are operated a t 70% of nominal airflow, and then increased to 100% when starting the calciner.
