This work discusses applications of analytical photocentrifuge LUMiSizer for estimation of the low-pressure compression-permeability characteristics of aqueous calcium carbonate sediments. Two approaches for estimation of compressibility-permeability parameters were tested. These approaches are based on(1) analysis of equilibrium height of sediment H-infinity versus centrifugal rotation speed Omega and (2) analysis of kinetic curves of the consolidation ratio U(t) at different rotation speeds Omega. The approach (1) allowed fair fitting of experimental H-infinity (Omega) data with parameters p(a) = 70.9 +/-0.9 Pa and beta = 0.1777 +/- 0.0005 in Tiller's equation relating the volume fraction phi and solid pressure p(s). The two independent approaches(1) and(2) evidenced the presence of the scaling law relating consolidation coefficient C and solid pressure p(s), C proportional to p(s)(gamma) with the similar exponents gamma approximate to 0.85 +/-0.03 (for the studied solid pressure region 5 kPa <= p(s) <= 75 kPa).
