The faster and the more thoroughly a dimension stone is dried, the lower the probability that the stone will experience frost or salt damage. The theory of the drying of porous building materials is described by Vos ( 1978 ), Snethlage ( 1984 ), Klopfer ( 1985 ), Kraus ( 1985 ), and Snethlage et al. ( 1986 ), and examples are given in Fig. 3.25 .
In a processing plant, natural stone can be cut by methods such as circular sawing (CS), frame sawing (FS), water jet cutting (WJC) and abrasive water jet cutting (AWJC). The efficiency of cutting systems can be compared using various parameters. In this study, the specific energy values were determined and compared to evaluate the …
Dimension stone is quarried by cutting, or separating by some other means, large blocks of stone from the natural rock mass. The size of individual block produced depends on a number of factors, including the homogeneity of the rock itself, the ability of the quarry operator to handle the rough stone, and the required end use for the stone once it has …
