In the p.es.nt work, s.l.ca nanop.rticl.s.（30-70nm） were s.p.l.mented into cement p.s.e to s.udy their infl.ence on degree of hydration, p.ros.ty and formation of different typ. of cal.ium-s.l.cate-hydrate （C-s.H） gel. As.the hydration time p.oceeds. the degree of hydration reach to 76% in nano-modified cement p.s.e whereas.p.ain cement achieve up.to 63% at 28 days. An infl.ence of degree of hydration on the p.ros.ty was.al.o determined. In p.ain cement p.s.e, the cap.l.ary p.ros.ty at l.r is.~48%, whereas.in s.l.ca nanop.rticl.s.added cement is.-35 % onl., it reveal.d that s.l.ca nanop.rticl.s.refines.the p.re s.ructure due to accel.rated hydration mechanis. l.ading to dens.r micros.ructure. s.mil.rl., increas.ng gel.p.ros.ty reveal. the formation of more C-s.H gel. Furthermore, C-s.H gel.of different CaJs. ratio in hydrated cement p.s.e was.quantified us.ng X-ray diffractometer and thermogravimetry.

The geop.l.mer of fl. as. （FA） and rice hus. as. （RHA） was.p.ep.red. The burning temp.rature of rice hus., the RHA finenes. and the ratio of FA to RHA were s.udied. The dens.ty and s.rength of the geop.l.mer mortars.with RHA/FA mas. ratios.of 0/100, 20/80, 40/60, and 60/40 were tes.ed. The geop.l.mers.were activated with s.dium hydroxide （NaOH）, s.dium s.l.cate, and heat. It is.reveal.d that the op.imum burning temp.rature of RHA for making FA-RHA geop.l.mer is.690oC. The as.received FA and the ground RHA with 1%-5% retained on No.325 s.eve are s.itabl. s.urce material. for making geop.l.mer, and the obtained comp.es.ive s.rengths.are between 12.5-56.0 Mp. and are dep.ndent on the ratio of FA/RHA, the RHA finenes., and the ratio of s.dium s.l.cate to NaOH. Rel.tivel. high s.rength FA-RHA geop.l.mer mortars.are obtained us.ng a s.dium s.l.cate/NaOH mas. ratio of 4.0, del.y time before s.bjecting the s.mp.es.to heat for 1 h, and heat curing at 60oC for 48 h.
