| Abstract: | The purpose of this study is to evaluate the possibility of using
granulated pumice as an alternative to fine aggregate in production of
lightweight cement mortar. The cement/pumice fine aggregate ratio is 1:3 for
pumice aggregate mortar. The water content is determined by flow table test. Compressive and flexural
strength, freeze-thaw resistance, sulfate resistance, water absorption and dry
unit weight of the mortars are determined. Mortar using 100% pumice as fine
aggregate developed strength in excess 12 MPa and had an oven dry density of
1140-1146 kg/m3 would satisfy the requirements for lightweight
mortar and it can be used as in cast
in place walls, load bearing and non-load bearing structures. Pumice aggregate
mortar is about 50% lighter than Portland cement control mortar due to the
replacement of comparatively heavier standard sand by lighter pumice aggregate.
The pumice aggregate mortar exhibits a higher frost resistance due to the
existence of voids in pumice aggregate. Pumice aggregate mortar showed better
performance showing higher residual strength at high temperatures compared
Portland cement mortar. The residual compressive strength reduction of pumice
aggregate mortar is higher than that of Portland cement mortar exposed to
freeze-thaw cycles. The use of pumice aggregate as sand provides the resistance
to sulfate attack. |
