Abstract

<p>The low burning-temperature type clinker with an adjusted mineral composition is expected to save energy in the burning process in cement production, but at the same time, reducing CO2 emissions from raw materials generated by decarboxylation of limestone is also an issue. In this study, concrete sludge, which is an industrial waste, was used as a calcium source for a part of clinker raw materials, and we investigated the influence of concrete sludge on the clinker mineral composition and the quality of cement for a low burning-temperature type composition. As a result, it was confirmed that, in the system under study, even when concrete sludge is used as part of the raw material for the low burning-temperature type clinker, it is possible to reduce CO2 emissions originating from the raw material by 22.9％ while maintaining the properties of cement.</p>
