    AB A method for processing paper mill sludge includes (a) admixing a

     suitable quantity of cement with a paper mill sludge, (b) admixing

     a lightwt. aggregate (e.g., expanded perlite or mica), (c) admixing

     a suitable quantity of fly-ash, and (d) admixing a suitable

     quantity of ***vermiculite*** . The expanded perlite,

     ***vermiculite*** and the ordinary fly-ash are dried and premixed

     with a cementitious binder along with any other extenders, such as

     fine silica sand or mica. The method includes the further step of

     admixing a wetting agent, a viscosity modifier, a chem.

     accelerator, acrylates and/or latex emulsions. The viscosity

     modifier is based on sodium or potassium-based polyacrylates or

     styrene-butadiene latex. The setting accelerator is selected from

     SnCl2, FeCl3, AlCl3 and CaCl2, as well as Al2(SO4)3,

     diethanolamine, and Zn(NO3)2. The resulting fiber-reinforced

     cement composite is suitable for the manuf. of partitioning or

     prefab wall elements, ceiling boards and doors, which can have

     excellent fire resistant, thermal insulating and sound dampening,

     strength and dimensional stability characteristics. This

     utilization approach also implies an addnl. benefit since pressure

     on the environment as a consequence of dumping is reduced.

    AB The compn. of primary minerals of sand fractions and secondary

     minerals of clay fractions were investigated of the polder soils

     developed from alluvio-marine deposits near Sapgyo-lake. The

     effects of topog. sequence on the physico-chem. properties and

     mineralogical characteristics were evaluated by using XRD, DTA, and

     TG. Soils located on the seashore side were more silt fraction

     with higher pH value more and exchangeable cations than soils in

     other locations. The dominant minerals in soil in order of

     abundance are quartz, feldspars, micas, chlorite, and amphibole.

     The dominant clay minerals in the polder soils are kaolinite,

     ***vermiculite*** , and illite. Hydroxy interlayer minerals are

     abundant in the clay fractions.

    AB Emanation thermal anal. (ETA), DTA, SEM, and XRD were applied for

     the characterization of the effect of Na+ and NH4+ ions used for

     satn. of natural Mg- ***vermiculite*** on the microstructure

     during heating. The microstructure changes were characterized by

     ETA under in situ conditions of samples heating in air in the temp.

     range 20-1300.degree.C. It was found that Na+ and NH4+ ions have a

     significant effect on the microstructure changes during heat

     treatment of the natural Mg- ***vermiculite*** sample satd. with

     these ions. For Mg- ***vermiculite*** and Na+ satd.

     ***vermiculite*** the temps. of the onset of the collapse of

     interlaminar space were detd. by ETA. Differences in thermal

     stability of the microstructure of dehydrated ***vermiculite***

     samples were obsd. by ETA: the microstructure of dehydrated Mg-

     ***vermiculite*** , and Na- ***vermiculite*** was found stable

     until 650 and 350.degree.C, resp. For dehydrated NH4-

     ***vermiculite*** the annealing of the microstructure started at

     730.degree.C. The onset temps. of the formation of new cryst.

     phases were indicated by ETA as the increase of the radon release

     rate. The onset temps. of the ordering of the ***vermiculite***

     structure or sintering under presence of the glassy stage (for Na-

     ***vermiculite*** ), resp., were detd. from the decrease of the

     radon release rate. The ETA results were confirmed by DTA, XRD and

     SEM.

    AB An expt. with two typical paddy soils from China and two clay

     minerals was conducted to study the effect of redn. of octahedral

     FeIII on fixation of NH4+ ions. Redn. of octahedral FeIII was

     achieved by treating soils and clay minerals with

     dithionite-citrate-bicarbonate (DCB) followed by dialyzing the

     samples under oxygen free conditions. Redn. of FeIII increased the

     neg. charge of interlayers and resulted in a significantly higher

     ammonium fixation. Close pos. correlations were found between the

     Fe2+ concn. or the ratio of Fe2+/Fe3+ and non-exchangeable NH4+-N.

     Thus, the redn. of octahedral Fe induced by flooding is one of the

     important prerequisites for the pronounced ammonium fixation in

     flooded soils. However, the relation between .DELTA.Fe2+ and

     .DELTA.fix-N was not stoichiometric.
