METHOD OF PRODUCINI,, MICRONISED AMORPHOUS BIOMASS SILICA ASH THIS INVENTION RELATES TO THE PROCILICTION OF MICRONISED AMORPHOUS BIONLASS SILICA 5 ASH VIA LI CONTROLLED INCINERATION OFBIOMASS. THE BIOMASS IS IN A-RICULTUNIL /@ASTE SELECTED FROM LI GROUP COMPRISING OFRICE HUSKS. KERNEL,.-,. BARKS. SHELLS. EMPTY FRUIT HUNCHES OF OIL PAHN, AND IN/, COMBINATION THERCOR % ITH HIL,11 SILICA CONTENT. THE BIONIASS IS PRE-TREATED HY ADDING LI CLAVC RIBL-C)LIS SLUDOC TO PRODUCC LI 11011102C11OLIS MIXTURE AND PRE-HEATED TO A LEIIIPCRA(LIRE OF 100 TO 1 80 OC 10 PI-OCILICC 10 A PRE-TREATED BIOMASS. THE PRE-TREIIIED BIOMASS IS T'CD INTO LI INCANS OFCOMBUSTION. PREFERABLY A FURNACE. WITH INULTIPLE DISTRIBUTED INLETS AND CONTROLLED TEMPERALURE RES,INIC TO PRODUCE THE AMORPHOUS BIORNASS SILICA ASH. THE CONTROLLED TCNIPERATURC REGINIC IS IN THE RANUE 1ROM 450 T TO 580 'C. THE AMORPHOUS BIOINASS SILICA LISH PRODUCED IS THEN SUBJECTED TO PARTICLE SIZE REDUCTION TO LI RAILGE OF 25 [LILL DOV1L TO 15 1 PILL BY NICANS OR MILLING. THE INICRONISED AMORPHOUS BIONLASS SILICA ASH PRODUCED IN THE PRESENT INVENTION IS SUITABLE TO LIC USED IN CENIENT TO IMPROVE WATERPROOLIM.- PROPERTY. THE MICRONISED AMORL)I)OLIS BIONIASS SILICA ASH INHIBITS THE REACTION OF CALCIU111 HYDROXIDE AND SUIPHATE BY REACTING %IFLI CALCIUILL HYDROXIDE TO J'ORM CALCIUM SILICATE HYDRATE WHICH CONTRIBUTES TO COMPRESSIVE STRENGTH AND WILL 20 LROW WITH TIME RESULTING IN PORE REFINEMENT IN THE MICROSTI-LICILIN.
