Coal comprises around 85-90% of the fuel consumed by the global cement industry. Over the past 20-30 years, a trend away from coal (and other fossil fuels)has been witnessed, particularly in Europe, due to concerns over CO2 emissions and problems with waste management. However, more recently, other regions have increased their use of coal for cemen...

Properties and behavior of limestone cement concrete and

2000年10月1日  The limestone cement concretes indicate lower resistance to freezing and thawing compared with the pure cement concrete. This fact may be attributed to the high value of the W/C ratio (Table 4) . The use of an air-entrained agent is expected to

Portland-Limestone Cement

Cement is made by grinding clinker—the main energy intensive ingredient—to a fine powder. Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of
