Two cements were made by grinding the clinkers separately in a laboratory ball mill. In another test series, in order to evaluate the usefulness of the PG as a direct set retarder for clinker, the plant clinker was interground with PG or RG.

The facing of cement walls usually consisted of smooth, irregularly shaped stones (opus incertum), of squared stones set on edge to form a neat network pattern (opus reticulatum, shortly after 100 BC), or of baked bricks (opus testaceum, from c.30 BC). These facings frequently provided the base for stucco or marble incrustation.

Introduction. The use of calcium phosphate cements (CPCs) has increased in recent years, because they are useful in the direct filling of defects and as cell matrices in tissue engineering [1, 2].Compared to other candidate replacement materials, the main merit of CPCs is their self-setting nature, which is particularly helpful when employed in the injectable form [].

Abstract The cement industry contributes about 5% to global anthropogenic CO 2 emissions, making the cement industry an important sector for CO 2-emission mitigation strategies.CO 2 is emitted from the calcination process of limestone, from combustion of fuels in the kiln, as well as from power generation. In this paper, we review the total CO 2 emissions from cement making, including process ...
